Thank you sir, my check engine light was on for about a year. I tried everything and could not remove it. After watching your video, and 10 minutes later the light is gone. Thank you so much, god bless. I have a 95' 960 model, thanks again sir.
By far the most helpful person on youtube for car issues. Having gone from volkswagon to jeep to now volvo these videos are the most clear cut and easy to follow i have ever seen
Thank you Robert. I tried disconnecting my battery for 15 minutes to clear my check engine light, however it's still on. I will try this. Your detailed directions have me feeling confident. Thanks again for keeping a lot of good vehicles on the road with your help. Just A little note: I have a 95 Volvo 960. The OBD boxes are located near the drivers side hood hinge.
Got the codes cleared and too the car out for a spin. It died suddenly after about 1.5 miles. Tried the diagnostic tool again and All the test ports on the A side show 1-1-1. I am at a dead end with this car. At least I know that I have tried and with the help of your videos, I feel that I have done my best. Wife wants to donate the car to NPR now.
I spent hours, because the led shone very poor. Man I forgot to deactivate my engine immobilizer with the little pinstick. After doing that I was able to read and delete some codes. Thanks Robert
Got It! I found the 121 code for the MAF sensor at A2 on the on board diagnostic tool! Thanks! Now I know I can buy a new sensor without wasting my money. I tried to clean the sensor already and it did not fix the problem. Car stalled about 1/2 mile from home and would not start again so I had to have t towed back home.
@@RobertDIY I should have tried that. The next day, the car started fine at 3 different times in the driveway. I tried to start it with the MAF unplugged and no go. I am going to try to check the camshaft position sensor today just in case.
Thanks Robert. You are a generous person to share your insights with these well presented videos. My1999 v70 T5 and I will be much healthier because of you.
Robert thanks for never ending videos that helping lots of us, I have 97 volvo glt 850 but didn't see that two stuff where it says A and B where can I clear code just in case I have some, i knew have some ... have a wonderful new year to u and your family...thanks Robert
Hiya Robert. My old 850 is as base spec as it gets. And it's not got all the A numbers. Only A2 A3 and A7 no loose wires or anything. It's a 1994 850 estate. Looking to try and get to the bottom of a lambda light lol
Hey Robert, thanks for the great video. I have used it to pull codes off my 1995 850 OBD-1 in the past. Right now when I use this technique I can only get codes from A7. when I plug into the other ports and hold the button for the same amount of time, it doesn't flash any code. No flashes at all for anything but A7, and I'm not able to reset the codes. On some of the other spots it dimly shows the red light when I plug it in, but on others, no light at all. I wondering if I need to replace anything in the plug system? Any thoughts for when it flashes for one but won't flash anything for the others? I'm pretty sure it has codes stuck in some other places that I've gotten codes in the past (like A3), and that's stopping me from resetting.
Thanks Robert. Still relevant! Got 2 codes. The A7 Port gave 1-2-2 “temp sensor interval too long”. Can’t find specific answer online. Does this mean the coolant temp sensor? Keep it up. Greetings from Holland
What a helpfull video Sr.!!!! Thank you so much. I´m having some inyection trouble with my 850 T5R, and this video will help me out for sure. Thanks a lot!!
I noticed you started working with A2 port (fuel system airs) and then without any reason, you changed to A3 port (ABS) and then reset the port. Can you explain that? Why you changed the port? If we get the "check engine" message how we know what port we need to start working with? Do we need to buy a special tool? and if this is the case what's the name of it? Thank you in advance for your answer.
Good day Robert, I have a volvo 850 1994 Non turbo. I have rebuilt it from a crash and it is working fine except for a few minor details.... I wanted to read the error codes on my OBD2 port and on 2 of my port, I do not get an error code, not even a 111.... the light iluminates when I press the test botton but after it stays off no blink. What could I check? Thank you
Hey Robert, for some reason somebody snipped off the wire on the diagnostic tool on my Volvo. Could I just use a jump wire(like the one from your fuel pump relay video) to do the code reading?
Robert, if I'm correct that this applies to the 960 as well, what I just discovered trying to check transmission codes on my 1993 960 (OBD1) is that instructions I find online say to plug the test lead into hole #1 to run this test. Problem is: when I check the OBD unit, hole #1 has no wires going to it. The harness that feeds the OBD unit A (there are two) only has wires going to 4 of the 8 holes, by design. And hole #1 is not one of them. Your thoughts? Thank you!
It may have an internal link. Does anything blink when you jump that hole? If not, you'll need to check a manual to see which port will give you transmission codes.
@@RobertDIY Nothing blinks, which was my first clue something wasn't right. At the very least it should give me a 1-1-1 reading. That's why I started looking at the OBD unit itself and discovered there is no wire to the #1 port. I'm following instructions for the pre-'96 960s with the OBD1. The instructions are the same here: www.volvotips.com/index.php/940-960/volvo-960-service-repair-manual/volvo-960-automatic-transmission-diagnosis-service-manual/ AND here: www.volvoclub.org.uk/faq/TransmissionAutoAW30.html#OnBoardDiagnostiCodesforAW3040SeriesAutomaticTransmissions No matter, I just thought you might have run across this particular peculiarity and have a thought on it. I was hoping to make some progress this weekend, but I can just ask my Volvo mechanic on Monday. I appreciate the quick response.
Several of the A ports in the OBDI box on my 1994 850 don't light up when i press the button. If I remove the box to clean the contacts is it safe to use isopropyl/rubbing alcohol, 70 or 90%? (I don't have electrical contact cleaner.)
Hi Robert, another great video. You are a wealth of information! Thank you so much for sharing it! I'm a single mom of a United States Marine and have limited income. Recently having problems with my ABS brakes engaging on their own while driving at about 25 miles per hour. Any suggestions? The wheel speed sensors were recalled years ago & the dealer replaced them for me. The car has just over 170,000 miles, but I would like to keep it running. Can you please give me suggestions. Is it the ABS module or wheel speed sensors that are bad, need cleaning, all or only bad one need to be replaced? Thank you in advance for your help.
What a fantastic video, so much valuable information! If you only knew how few mechanics know this about our old Volvos... I have a Volvo '92 960 ;-) I do have one question - It looks like that between you reading your error codes, and you resetting your codes, you had moved the jumper cable from port 2 to port 3 - is that correct? And why?
Hi Robert. I am in dire need of a new obd1 diagnostic unit A box. I purchased my 1994 manual 850 NA amd the wire was missing from the unit A box and can't find one anywhere online. Please let me know if you have one or can get one I can pay asap I am in Canada. Thank you
Hi Rob. My son own a 1988 760 volvo turbo and for some reason when you give normal gas it's running perfect ,but when give gas like to pass somebody or an emergency the car loose power inmediately and can get more than 30 miles an hour. Any ideas. We change MAF , plugs, cat, rebuilt injectors, check muffler and nothing. Any sugestions? it is this model intercooler 760 with a 2.3 L OBD1 compatible or something more obsolete. thank you Rob
Hi Robert , thanks for your videos I've found out how to fix loads of stuff on my v70xc thanks to your channel. Have you ever encountered an intermittent abs code 0074 hydraulic valves faulty signal? My abs sometimes intermittently kicks in under light braking and I've had the abs and stability light come on randomly for a few seconds after 50mph. I know it's a long shot but could it have anything to do with worn tyres on the front and decent ones on the rear being an all wheel drive?
Not sure what year model your car is, however, for most of them, if the AWD system is still installed on the vehicle, it is critical to keep all 4 of the tires the same wear ratio/condition. If you fail to do that, you can destroy the AWD system pretty quick.
@@RobertDIY it's a 1999 v70 xc. At first I thought it was just a glitch with cold weather as the lights only stay on a few seconds then go off and only seems to be after 50mph. I put the tyre pressures slightly higher in the front to compensate a bit and last I tried the lights didn't come on but the abs did kick in randomly under light braking. It's booked in to change the tyres soon so will see if it makes any difference but I doubt it
Hey robert, I have a 850 with a fresh replaced battery and wires. I run thru the codes and its all codes for sensors.. after reseting the check light goes away, but when restarting the computer thru ignition key the light comes back. Im fairly certain my sensors are all good.. any fixes? Thx
So are there any other things needing to be done when replacing this ABS module? Our 1997 Volvo 850 has the same thing, though the ABS light will go off, it does come on occasionally. I bought the ABS with socket and will replace it, and wondered if you have to have any other information or software updated after this is reinstalled? Thanks for any help in this area.
Hi! Great video! I have a problem with my automatic 850 -93 140hps. It only drives in reverse, transmission oil looks good I get fault code 232 in the a1 port. Have tried switching the computer for the transmission without results. Is the best solve to just replace that transmission or is there an easier fix? Thx /Elliot
@@RobertDIY i read somewhere that you can test the pnp switch by putting it in reverse and if the reverse lights turn on, it should be OK. So I tried this and the lights turn on in R. Could the pnp switch still be the problem? Thx!
@@RobertDIY Hi again, I changed the pnp switch today. Same problem still, car drives perfectly in R, but doesn't drive at all in any other gear. Do you have any ideas for fix? Maby time to start looking for a new gearbox
hello Robert, i have a 1996 850 GLT. It does not have the jumper box and i have the CEL, ABS and SERVICE lights on. the Service lights comes on and off, any advice on how to get rid of the lights.
Hi Robert.When you reset the codes, by pressing 10 and 10 sec with the jumper on the A3 port for instance, do you reset only the codes stored on that port A3, or all the codes in the system??...many thanks
Would the process described here apply to a 1993 940s with turbo? I know it seems like a dumb question, but I'm not very car savvy, and need to be sure before trying this on my vehicle.
Hi Robert I have a Volvo 95 850 the on board DTC Red light come on but don't blink check engine light is on I guess it no functioning properly I plugged on 2 press light come on but don't blink ..? what's wrongs?
Hello Robert: I have replaced a number of parts on my 1994 Volvo 850 wagon (non-turbo) but am looking to replace the ECU/ECM. The car has a 5.1 and 6.2 number on the module as well as the part number. I can find replacements for both modules (with matching part numbers) but cannot find out which modules does what?? The problem is basically that the car starts right away and automatically rev's to 2500 rpm the dies. If I pump it it will (after a time) idle but it is rough. Can you please help to clarify which module I should replace? thanks Grant
@@RobertDIY Hello: The error codes have been cleared by the fellow I have helping me. I believe he said they were emission codes . The check engine light is on.
My main issue is the check engine light. I bought my 94 850 in early May, and the tabs expired. Little did I know the cel can not be on or you will not pass your emissions testing in the state of Washington. The car runs like a dream I love it so much, but will this keep the light off just so I can pass my testing, and am able to drive?
Sorry, My question is will resetting the codes turn off the light forever? Or will it turn back on once its driven for a while. My step dad and I have gone through the codes and fixed everything that came back. The main problem was the PCV system. Smoke was coming out of the dipstick.
Hey Robert, I replaced the mass air flow sensor on my volvo 850 1994. Check engine light went away on its on after I unplugged the battery and connected it back up. So I Did not have to reset that. However, I feel like the car still seem to run lean because the rpm seems to stay about 850 rpm. It does not run rich because the rpm isnt going above 1000 at idle. Could the idle air control valve be faulty? Does it ever need replacing or is this some other problem?
Robert DIY is there an email where i can send you a picture of the gauge cluster so that you can eyeball it and tell if it looks like 840 to you? I am having this weird feeling because every time i shift from park to drive/reverse, the rpm fluctuates for a quick second and then becomes constant. Is that normal? Is it possible to diagnose or findout if this weird feeling I am getting is false? Since there is no lights on except ABS/Tracs, which means obd in the car wont give me codes on this cause. So can I check this forsure in any other way?
Will this method also work for clearing SRS light on a 93 940 after driver airbags been deployed? I am trying to get my seatbelts functioning again after the accident and it would be nice if I could get the SRS light off too.. Would it come off if I swapped an airbag from junk yard?
Hi Robert. I did this with my 93 and all went well except for the A3, no light came on at all, ant that’s the main one I was hoping for since my abs light is on, any suggestions?
Hi Robert, plugged in socket A2 my led is on constantly (with about half power) and codes can not be flashed. Does not react to pressing it for one second (or any other length). Disconnecting the battery or turning injection off/on does not make any difference. All other sockets work fine. Do you have any idea how to check/fix this socket? Volvo 850 T5 94´ Thank you:)
@@RobertDIY Hey Robert I am having same issue. B1 Socket makes LED stay on, does not react to button presses or holds Should I replace the whole OBD1 reader ? Thank you!
Hi Robert, Thank you for your postings, they very informative. I have a sticky issue. My ABS light is on all the time and when I connect the jumper on terminal #3 the light stays on and does not flash any code. I have replaced the Controller unit and the ABS quickly came back on, after a while. It turned back off and stayed that way for a long while. Recently the light came back on once again, and as I tried to check and clear the code on terminal #3, the terminal light goes on right when I connect the jumper and stays on no matter what. It feels like there is some kind of short circuit somewhere, any ideas where I should look? Again, thank you for your good information. Paris
Paris Psaros You can replace that jumper box with a used one. It may have a loose wire. You need to find the code and chase the problem from there. - th-cam.com/video/s_34WT3AbWc/w-d-xo.html
Robert DIY yes sir I got a mass air flow sensor code so I got a new one crank sensor code which I replaced as well as o2 sensor which I just ordered I cleared all the codes but after I ran the car all three codes came back
Hey Rob I have a 1995 Volvo 850 I still can't get the engine light to come off. I tried serval times I did get theses codes 314, 212, 213, 214 out of port 3. I hold the button down like you said once I ran threw the codes still the check engine light is on.
Ok thanks. My coworker referred me to a machanic that fixes European cars he's good from what they told me. I'll let you know what happens. Thanks for all the advice. I was a VW guy now I'm down with Volvo.
Hi Robert, do you have a suggestion? I can't clear a 4-4-4 code for A3 port? After the initial press of the button 7-10 seconds I am not getting the red light to reappear so I can clear code. No other codes exist except for the B2 cruise port throwing 1-2-2, which I understand would go away if I tested after a drive with cruise on and test without shutting car down. ABS light goes out a few seconds after startup. The ABS hydraulic pump noise/test functions at 20-30 MPH indicating pump is OK. 1994 Volvo 850 N/A 5-speed.Thanks!
+Robert DIY No CEL. I had an ABS light temporarily because of bad connection with the big connector on driver side strut tower after I moved it to install a strut tower brace. I checked for coded in thePOBD1 after I reconnected to see if I needed to clear ant related codes. The 4-4-4 in A3 and the typical B2 1-2-2 for the cruise if tested without driving along 1st. I tried 4-1-5-1 to clear the 4-4-4 but it did not work like resetting a CEL or Service reminder. Resetting the ECU did not clear code
+David Silbert So the issue is that while the jumper is plugged into A3, holding the button for 7-10 seconds does not make the red light come on again after 3 seconds so I can hold the button for the next 7-10 push to clear the code. I did try entering 4-1-5-1 and the red light did stay on after the 4, but when I continued entering 1-5-1 the red light flashed the 4-4-4 code before I could continue the 1-5-1. Do you know if there is a code I can manually enter to clear the 4-4-4 in A3 port or do you think that in time it will clear itself?
+Robert DIY I sprayed the button and ports with electro-contact cleaner and searched online for Volvo 850 4-4-4. I read a lot including VolvoTips, the factory repair pages and MVS. I was able to clear the code. I drove the car about 10 miles. When I returned home I put the jumper back in A3. I turned the ignition key to on and viewed the code twice. I performed the 7 seconds button press but this time the red light did come on after 3 seconds. Did the second 7 seconds button press. The light went out. I did the 1 second press for codes and got 1-1-1 - trouble code cleared. I think the secret was to check for codes till they repeat and then to the clear procedure all during one session. I'll check it again after the 40 mile round trip to work tomorrow and report back if it returns.
@@RobertDIY how can i follow the instructions if you tell one thing and show another? If the instructions is the same and I can ignore why the plug was in A3 I’ll try it out 😅 Got a beautiful vine red 850 1996
Hi! I drive a 1994 960 Wagon. The diagnostic setup looks identical to the one on this 850, and I'm only getting flashes from port 2, when I insert the little jumper in any other port and hold the button, nothing flashes back.... what could be the problem?
+Robert DIY no light at all! and I'm concerned with the car because there's this peculiar tapping noise that happens when I push the gas pedal slightly, let go, and push it again, and it only happens when I'm going 35-50. the oddest thing is that it comes with the front end. My mechanic (who doesn't have much experience with older volvos) is baffled as well..... since you're experienced with volvos, have you ever heard of this? I AM getting some codes from the oxygen sensor but I wouldn't think that would be related..?
Hey Robert. My check engine light was on for about 5 days and it turned off yesterday. However, when I start my car the check engine light does not show at all. Should I worry about this?
hey robert im having trouble. my red light is automatically on and the button doesnt do anything when i turn my key. what does this mean? its in a1. im checking for a flashing orange arrow problem. it seems the car shifts fine it just has that arrow when i go to drive
turns out im also missing the whole connector to a5... there isnt even a wire hanging out anywhere. some of the other ones no light comes on, and/or same thing with A1
@@RobertDIY ok i did that and i get A1 232 and nothing from ignition. my main issue and question is if no speed sensor can cause the flashing arrow and flashing economy light. ive drove around counted shifts dozens of times and it seems to shift perfectly, no sign of this "limp home mode". so is this a good diagnosis of the light? just being from no VSS
I put my 01 Volvo XC70 up on jack jacks to check for a vibration. Ran it up to like 60 mpg. Now the ABS light wants to be serviced. Any idea to fix this ?
Hi. I have the 1995 volvo 850 t5. I have read the codes 213 and 214 from the A3 (abs) socket in error codes. I am getting error code 113 at entry a7(Combined Instrument). what is this? what is wrong with these codes? and the a6 socket seems empty, why? Thanks

Hey robert, here once again asking for your help. I got a volvo 850 1993 with about 198xxx kilometers on it. I have 2 problems with it. One is that it wont idle sometimes but i temporarely fixed that by putting a rubber piece over the sensor by the carburetor that activates the iac. The other problem i have if i drive over a speed bump the car just stalls, there is sometimes i can avoid staling by putting my foot on the throttle. The lamp for error with something with the electrical at the engine lights up for a little while. After that happens the engine takes alot more time to start. I have tried to read the error code and i have 2 error codes from A4 but that isnt in the error list you linked. Any tips? Any help is appreciated.
@@RobertDIY ive checked with a voltmeter and tried to pull at the battery terminal, and even checked the ground to the engine block but none of them was loose and i had 14,4 voltage at the block. Didnt find anything wrong with the wiring.

Hi, i cant seem to pull codes from the b6. nothing happends when i push the led button, it only lights when i press then nothing more happends. i think i have the same issue on other ports aswell if i remember. I wanna see the codes since the passenger power seat (back rest) wont fold up and down the motor makes a sound 1second then quits. guess it needs to be recalibrated.. dunno how to do that.
I was able to get the codes cleared from the "A" OBD tool. Ran the car for a while back and forth in the driveway and no problems. Now I am really confused and I know I have to take this car out on the road to really test it. This time I will get my wife to follow me in the other car. I guess if it stalls again, it wil throw a code and then I will be sure if it's the MAF sensor or the Cam sensor.

I'm pretty sure it has codes stuck in some other places that I've gotten codes in the past (like A3), and that's stopping me from resetting.
Probably needs to have the box cleaned out or replaced.
Thanks Robert. Still relevant! Got 2 codes. The A7 Port gave 1-2-2 “temp sensor interval too long”. Can’t find specific answer online. Does this mean the coolant temp sensor? Keep it up. Greetings from Holland
That's what it sounds like to me. If the wires are connected properly, I'd replace the sensor.

Good day Robert, I have a volvo 850 1994 Non turbo. I have rebuilt it from a crash and it is working fine except for a few minor details.... I wanted to read the error codes on my OBD2 port and on 2 of my port, I do not get an error code, not even a 111.... the light iluminates when I press the test botton but after it stays off no blink. What could I check? Thank you
Which ports are they?
Hey Robert, for some reason somebody snipped off the wire on the diagnostic tool on my Volvo. Could I just use a jump wire(like the one from your fuel pump relay video) to do the code reading?
you can re-connect the wire. It likely broken off.
Thank you once again Robert!
This guide worked for my 1995 Volvo 960. Had the lambda light on which is the same as check engine light I guess
Robert, if I'm correct that this applies to the 960 as well, what I just discovered trying to check transmission codes on my 1993 960 (OBD1) is that instructions I find online say to plug the test lead into hole #1 to run this test. Problem is: when I check the OBD unit, hole #1 has no wires going to it. The harness that feeds the OBD unit A (there are two) only has wires going to 4 of the 8 holes, by design. And hole #1 is not one of them. Your thoughts? Thank you!
It may have an internal link. Does anything blink when you jump that hole? If not, you'll need to check a manual to see which port will give you transmission codes.
@@RobertDIY Nothing blinks, which was my first clue something wasn't right. At the very least it should give me a 1-1-1 reading. That's why I started looking at the OBD unit itself and discovered there is no wire to the #1 port. I'm following instructions for the pre-'96 960s with the OBD1. The instructions are the same here: www.volvotips.com/index.php/940-960/volvo-960-service-repair-manual/volvo-960-automatic-transmission-diagnosis-service-manual/ AND here: www.volvoclub.org.uk/faq/TransmissionAutoAW30.html#OnBoardDiagnostiCodesforAW3040SeriesAutomaticTransmissions No matter, I just thought you might have run across this particular peculiarity and have a thought on it. I was hoping to make some progress this weekend, but I can just ask my Volvo mechanic on Monday. I appreciate the quick response.
Thanks a lot on this video ! Explained and helped me trouble shoot and further investigate some issues i was having
+Ronell “Ronl” J Good deal, thanks for watching.
Hi Robert. Thanks for the help. Quick question. On A2 section i got error code 122, but its not on your list. What that means?
I think it means that the car has not reached the speed required to test that system during that drive cycle.
Awesome. Thank you Robert!
+Patrick McKenna you are welcome.
Several of the A ports in the OBDI box on my 1994 850 don't light up when i press the button. If I remove the box to clean the contacts is it safe to use isopropyl/rubbing alcohol, 70 or 90%? (I don't have electrical contact cleaner.)
sure.
Well, I am confused! I own a 1995 850 but there is no OBD port under my hood. From the OBD2 port (inside) I can't get any information for some reason.
Have you checked the fuse?
@@RobertDIY yes! The computers connect but can't get any info from the engine. We did manage to get info from abs.
Hi Robert, another great video. You are a wealth of information! Thank you so much for sharing it! I'm a single mom of a United States Marine and have limited income. Recently having problems with my ABS brakes engaging on their own while driving at about 25 miles per hour. Any suggestions? The wheel speed sensors were recalled years ago & the dealer replaced them for me. The car has just over 170,000 miles, but I would like to keep it running. Can you please give me suggestions. Is it the ABS module or wheel speed sensors that are bad, need cleaning, all or only bad one need to be replaced? Thank you in advance for your help.
I don't even know what kind of car you have???
@@RobertDIY I apologize!! I have a 1999 Volvo s70 base model
No warning lights.
You are amazing. God bless you!
Thanks for watching.
What a fantastic video, so much valuable information! If you only knew how few mechanics know this about our old Volvos... I have a Volvo '92 960 ;-)
I do have one question - It looks like that between you reading your error codes, and you resetting your codes, you had moved the jumper cable from port 2 to port 3 - is that correct? And why?
Different ports are for different systems.
Helpfull video as usual!!!
Thanks for watching.
Hi Robert. I am in dire need of a new obd1 diagnostic unit A box. I purchased my 1994 manual 850 NA amd the wire was missing from the unit A box and can't find one anywhere online. Please let me know if you have one or can get one I can pay asap I am in Canada. Thank you
I have one. Send me an email.
Hi Rob. My son own a 1988 760 volvo turbo and for some reason when you give normal gas it's running perfect ,but when give gas like to pass somebody or an emergency the car loose power inmediately and can get more than 30 miles an hour. Any ideas. We change MAF , plugs, cat, rebuilt injectors, check muffler and nothing. Any sugestions? it is this model intercooler 760 with a 2.3 L OBD1 compatible or something more obsolete. thank you Rob
gabriel painter Is there a tear or something in one of the intercooler or turbo tubes?
gabriel painter could have been dirty or semi clogged fuel filter
Hi Robert , thanks for your videos I've found out how to fix loads of stuff on my v70xc thanks to your channel. Have you ever encountered an intermittent abs code 0074 hydraulic valves faulty signal? My abs sometimes intermittently kicks in under light braking and I've had the abs and stability light come on randomly for a few seconds after 50mph. I know it's a long shot but could it have anything to do with worn tyres on the front and decent ones on the rear being an all wheel drive?
th-cam.com/video/5Xmesel_NZY/w-d-xo.html
Not sure what year model your car is, however, for most of them, if the AWD system is still installed on the vehicle, it is critical to keep all 4 of the tires the same wear ratio/condition. If you fail to do that, you can destroy the AWD system pretty quick.
@@RobertDIY it's a 1999 v70 xc. At first I thought it was just a glitch with cold weather as the lights only stay on a few seconds then go off and only seems to be after 50mph. I put the tyre pressures slightly higher in the front to compensate a bit and last I tried the lights didn't come on but the abs did kick in randomly under light braking. It's booked in to change the tyres soon so will see if it makes any difference but I doubt it
Thank you I'll give that a try. Thanks for your help. Love from the UK. 🙂
Hey robert, I have a 850 with a fresh replaced battery and wires. I run thru the codes and its all codes for sensors.. after reseting the check light goes away, but when restarting the computer thru ignition key the light comes back. Im fairly certain my sensors are all good.. any fixes? Thx
If you have error codes something needs to be fixed.
So are there any other things needing to be done when replacing this ABS module? Our 1997 Volvo 850 has the same thing, though the ABS light will go off, it does come on occasionally. I bought the ABS with socket and will replace it, and wondered if you have to have any other information or software updated after this is reinstalled? Thanks for any help in this area.
+John Luchsinger what did the video say?
WHAT DOES IT MEAN WHEN THE ABS AND TRACKS GOME UP ONCE IN A WHILE? K
Hi! Great video!
I have a problem with my automatic 850 -93 140hps. It only drives in reverse, transmission oil looks good
I get fault code 232 in the a1 port. Have tried switching the computer for the transmission without results.
Is the best solve to just replace that transmission or is there an easier fix?
Thx
/Elliot
I would try the PNP switch.
@@RobertDIY i read somewhere that you can test the pnp switch by putting it in reverse and if the reverse lights turn on, it should be OK. So I tried this and the lights turn on in R. Could the pnp switch still be the problem?
Thx!
@@RobertDIY Hi again, I changed the pnp switch today. Same problem still, car drives perfectly in R, but doesn't drive at all in any other gear. Do you have any ideas for fix?
Maby time to start looking for a new gearbox
I think the 232 code in the A1 port means the transmission speed sensor is bad.
You have been alot of help with my Liyah. Keep sending these videos
Can this be done on the 1999 s70 model
No, if you own a Volvo, you really should purchase an OBD2 tool.
Hi, thank you for The information. It really helped me out with my problem. Tack. (swedish).
Glad it helped!

Hi Robert.When you reset the codes, by pressing 10 and 10 sec with the jumper on the A3 port for instance, do you reset only the codes stored on that port A3, or all the codes in the system??...many thanks
Only port 3
@@RobertDIY thanks Robert
Thanks a lot for yours videos!!!
Do you know, for what is this green wire with red band wich stay infront on OBD1 box?
Thanks in advance!
No idea
Would the process described here apply to a 1993 940s with turbo? I know it seems like a dumb question, but I'm not very car savvy, and need to be sure before trying this on my vehicle.

Hi Robert I have a Volvo 95 850 the on board DTC Red light come on but don't blink check engine light is on I guess it no functioning properly I plugged on 2 press light come on but don't blink ..? what's wrongs?
My guess would be that the box is bad or has a bad connection.
Hello Robert: I have replaced a number of parts on my 1994 Volvo 850 wagon (non-turbo) but am looking to replace the ECU/ECM. The car has a 5.1 and 6.2 number on the module as well as the part number. I can find replacements for both modules (with matching part numbers) but cannot find out which modules does what?? The problem is basically that the car starts right away and automatically rev's to 2500 rpm the dies. If I pump it it will (after a time) idle but it is rough. Can you please help to clarify which module I should replace? thanks Grant
What error codes does it have?
@@RobertDIY Hello: The error codes have been cleared by the fellow I have helping me. I believe he said they were emission codes . The check engine light is on.
If the CEL is on, there are codes in the system. Use the video and get them.
@@RobertDIY Thanks you will do
Hi Robert ! Thanks a lot, the CE light is gone. I get a 521 code Front HO2S Preheating (850 2.5L 10v 1994 non turbo). What's next ?
Replace the sensor...
If I have some trouble with my 850 94 model, I always know where I can find answers
Thanks for watching.
My main issue is the check engine light. I bought my 94 850 in early May, and the tabs expired. Little did I know the cel can not be on or you will not pass your emissions testing in the state of Washington. The car runs like a dream I love it so much, but will this keep the light off just so I can pass my testing, and am able to drive?
I don't understand your question. Why is the light on?
Sorry, My question is will resetting the codes turn off the light forever? Or will it turn back on once its driven for a while. My step dad and I have gone through the codes and fixed everything that came back. The main problem was the PCV system. Smoke was coming out of the dipstick.
LOL, as long as there are no issues the light will stay out. If an issue comes up, it will return.
Hey Robert, I replaced the mass air flow sensor on my volvo 850 1994. Check engine light went away on its on after I unplugged the battery and connected it back up. So I Did not have to reset that. However, I feel like the car still seem to run lean because the rpm seems to stay about 850 rpm. It does not run rich because the rpm isnt going above 1000 at idle. Could the idle air control valve be faulty? Does it ever need replacing or is this some other problem?
Idle is supposed to be 840.
Robert DIY is there an email where i can send you a picture of the gauge cluster so that you can eyeball it and tell if it looks like 840 to you?
I am having this weird feeling because every time i shift from park to drive/reverse, the rpm fluctuates for a quick second and then becomes constant. Is that normal?
Is it possible to diagnose or findout if this weird feeling I am getting is false? Since there is no lights on except ABS/Tracs, which means obd in the car wont give me codes on this cause. So can I check this forsure in any other way?
Will this method also work for clearing SRS light on a 93 940 after driver airbags been deployed?
I am trying to get my seatbelts functioning again after the accident and it would be nice if I could get the SRS light off too.. Would it come off if I swapped an airbag from junk yard?
e Kbauer If you replace all of the damaged component, yes you can reset the light.

Hello, please can you tell me how i can read codes on a 850 2.5 TDI from 1996 ? my OBD2 scan tool does not work on this car.... thank you in advance
get another scan tool.
Hi Robert. I did this with my 93 and all went well except for the A3, no light came on at all, ant that’s the main one I was hoping for since my abs light is on, any suggestions?
Not really. You can disconnect the box/reader and clean off the contacts. If that doesn't work, replace the box.
Robert DIY thanks for all you do, you have helped me with so much!
Hi Robert,
plugged in socket A2 my led is on constantly (with about half power) and codes can not be flashed. Does not react to pressing it for one second (or any other length). Disconnecting the battery or turning injection off/on does not make any difference. All other sockets work fine. Do you have any idea how to check/fix this socket?

Thank you:)
+volvo850t5 probably a bad box.
@@RobertDIY Hey Robert I am having same issue.
B1 Socket makes LED stay on, does not react to button presses or holds
Should I replace the whole OBD1 reader ?
Thank you!
Hi Robert,
Thank you for your postings, they very informative.
I have a sticky issue. My ABS light is on all the time and when I connect the jumper on terminal #3 the light stays on and does not flash any code. I have replaced the Controller unit and the ABS quickly came back on, after a while. It turned back off and stayed that way for a long while. Recently the light came back on once again, and as I tried to check and clear the code on terminal #3, the terminal light goes on right when I connect the jumper and stays on no matter what. It feels like there is some kind of short circuit somewhere, any ideas where I should look?
Again, thank you for your good information.
Paris
By the way, the volvo in question is a 1994 850 non turbo
Paris Psaros You can replace that jumper box with a used one. It may have a loose wire. You need to find the code and chase the problem from there. - th-cam.com/video/s_34WT3AbWc/w-d-xo.html
Robert DIY Thank you Robert, Any idea where I should look for jumper box replacement, other than a junkyard.
Online or I can send you one if you need me to.
I can't seem to find one online. I'd gladly purchase one from you if you have them.
Such a simple, user-friendly system. Great! Volvo FTW
n8trsho Yes it is.
Just a quick question: I ripped the cord off the plug on my OBD1 unit on my '95 Volvo 960. What's the best way to put it back together? Thanks!
Solider.
@@RobertDIY What's the best way to go about doing that, with not much wire to work with?
Remove it and take it to a bench.
Hi Robert! The jump wire is disconnected from the port (A side) on my car - do you know how to remedy this?
+Sara Anger you may be able to repair it with solder. I usually replace them.
Hey Robert I'm getting a 232 121 113 on a 90 240 I've recently replace the mass air flow sensor and wondering if an o2 sensor may be the issue
Have you googled the codes?
Robert DIY yes sir I got a mass air flow sensor code so I got a new one crank sensor code which I replaced as well as o2 sensor which I just ordered I cleared all the codes but after I ran the car all three codes came back
Hey Rob I have a 1995 Volvo 850 I still can't get the engine light to come off. I tried serval times I did get theses codes 314, 212, 213, 214 out of port 3. I hold the button down like you said once I ran threw the codes still the check engine light is on.
Maybe you need to fix the problems.
Ok thanks. My coworker referred me to a machanic that fixes European cars he's good from what they told me. I'll let you know what happens. Thanks for all the advice. I was a VW guy now I'm down with Volvo.
Hi Robert, do you have a suggestion? I can't clear a 4-4-4 code for A3 port? After the initial press of the button 7-10 seconds I am not getting the red light to reappear so I can clear code. No other codes exist except for the B2 cruise port throwing 1-2-2, which I understand would go away if I tested after a drive with cruise on and test without shutting car down. ABS light goes out a few seconds after startup. The ABS hydraulic pump noise/test functions at 20-30 MPH indicating pump is OK. 1994 Volvo 850 N/A 5-speed.Thanks!
+David Silbert I don't understand your question, do you have a CEL?
+Robert DIY No CEL. I had an ABS light temporarily because of bad connection with the big connector on driver side strut tower after I moved it to install a strut tower brace. I checked for coded in thePOBD1 after I reconnected to see if I needed to clear ant related codes. The 4-4-4 in A3 and the typical B2 1-2-2 for the cruise if tested without driving along 1st. I tried 4-1-5-1 to clear the 4-4-4 but it did not work like resetting a CEL or Service reminder. Resetting the ECU did not clear code
+David Silbert So the issue is that while the jumper is plugged into A3, holding the button for 7-10 seconds does not make the red light come on again after 3 seconds so I can hold the button for the next 7-10 push to clear the code. I did try entering 4-1-5-1 and the red light did stay on after the 4, but when I continued entering 1-5-1 the red light flashed the 4-4-4 code before I could continue the 1-5-1. Do you know if there is a code I can manually enter to clear the 4-4-4 in A3 port or do you think that in time it will clear itself?
If there is NO CEL, there is nothing to clear.
+Robert DIY I sprayed the button and ports with electro-contact cleaner and searched online for Volvo 850 4-4-4. I read a lot including VolvoTips, the factory repair pages and MVS. I was able to clear the code. I drove the car about 10 miles. When I returned home I put the jumper back in A3. I turned the ignition key to on and viewed the code twice. I performed the 7 seconds button press but this time the red light did come on after 3 seconds. Did the second 7 seconds button press. The light went out. I did the 1 second press for codes and got 1-1-1 - trouble code cleared. I think the secret was to check for codes till they repeat and then to the clear procedure all during one session. I'll check it again after the 40 mile round trip to work tomorrow and report back if it returns.
I noticed you moved the pin from A2 to A3 during the mid last part but than at the end you’re back at A2…. What’s that about ?
Don't get distracted. Just follow the instructions.
@@RobertDIY how can i follow the instructions if you tell one thing and show another? If the instructions is the same and I can ignore why the plug was in A3 I’ll try it out 😅 Got a beautiful vine red 850 1996
Hi Robert...when i put the cable on nº3 and start the ignition on, the light turns on right a away and stays there! Doesn´t let me do nothing!!

Hi!
I drive a 1994 960 Wagon. The diagnostic setup looks identical to the one on this 850, and I'm only getting flashes from port 2, when I insert the little jumper in any other port and hold the button, nothing flashes back.... what could be the problem?
+Car Wash Studios Probably no codes in the other systems. Do they flash 1-1-1?
+Robert DIY no light at all! and I'm concerned with the car because there's this peculiar tapping noise that happens when I push the gas pedal slightly, let go, and push it again, and it only happens when I'm going 35-50. the oddest thing is that it comes with the front end. My mechanic (who doesn't have much experience with older volvos) is baffled as well..... since you're experienced with volvos, have you ever heard of this? I AM getting some codes from the oxygen sensor but I wouldn't think that would be related..?
+Car Wash Studios Are you pumping 91+ octane?
+Robert DIY the car was my moms, and she always used 88. now that the car is mine I make sure to use premium grade.
How about the oil filter? Is it Mann? Maybe a lifter.
Hey Robert. My check engine light was on for about 5 days and it turned off yesterday. However, when I start my car the check engine light does not show at all. Should I worry about this?

hey robert im having trouble. my red light is automatically on and the button doesnt do anything when i turn my key. what does this mean? its in a1. im checking for a flashing orange arrow problem. it seems the car shifts fine it just has that arrow when i go to drive
turns out im also missing the whole connector to a5... there isnt even a wire hanging out anywhere. some of the other ones no light comes on, and/or same thing with A1
Just check the ignition and transmission ports.
@@RobertDIY ok i did that and i get A1 232 and nothing from ignition. my main issue and question is if no speed sensor can cause the flashing arrow and flashing economy light. ive drove around counted shifts dozens of times and it seems to shift perfectly, no sign of this "limp home mode". so is this a good diagnosis of the light? just being from no VSS
btw i also got p0500 (no speed sensor) from two different obd2 scan tools.
I put my 01 Volvo XC70 up on jack jacks to check for a vibration. Ran it up to like 60 mpg. Now the ABS light wants to be serviced. Any idea to fix this ?

Hey robert, here once again asking for your help. I got a volvo 850 1993 with about 198xxx kilometers on it.
I have 2 problems with it. One is that it wont idle sometimes but i temporarely fixed that by putting a rubber piece over the sensor by the carburetor that activates the iac.
The other problem i have if i drive over a speed bump the car just stalls, there is sometimes i can avoid staling by putting my foot on the throttle. The lamp for error with something with the electrical at the engine lights up for a little while. After that happens the engine takes alot more time to start. I have tried to read the error code and i have 2 error codes from A4 but that isnt in the error list you linked. Any tips? Any help is appreciated.
Have you checked your wires at the battery to make sure none are loose?
