Replaced the transmission control module on my 2002 dodge grand caravan work van due to been stuck in limp mode 2nd gear, after install the problem was still there and was disheartened, more research led me to realizing i had to reset the TCM and then i came across your video, Initially i was skeptical but gave it a go, IT WORKS!!, not only does it work, its works better than ever. Thank-you so much for the information
Damn bro how much was the new transmission control module ? I had my check engine light come on, took it to autozone, n dey said I needed a new one. They were going for like $600-$800 so I needed to find another way 😂. I found out about resetting the cars computer, so I did it (and also changed my transmission fluid because it actually really needed a change) n now my car was running great. But about a week after I reset it, my gauge that tells me if my car is overheating or not, isn’t working. I’m gonna do another reset just to see if it will fix but I’m not sure

After replacing my battery in my V60 2012 the car infotainment system vent totaly crazy. Nothing worked, every fuse was ok. The car had around 20 error codes.

What the hell is a V20? A Volvo? They have a completely different electrical system than the Chevy truck in this video and doing what is did accomplished nothing except perhaps a better connection from the battery to the alternator and cars electrical system. It is no longer B+ to the dash, it is serial data thru one wire and some two wires twisted 9 times per foot to prevent RFI. Don't know what that is...Stop! With battery disconnected & jump positive to negative is simply drain capacitors which is fruitless, waist of time. From 1998 and newer, the dash or instrument cluster (IP) has power, ground and class-2 serial data to operate the shifter's position and gages. Those signals are class-2 a signal from 0-7 volts and a good volt-ohm-meter on pin two of the OBD-2 connector (Cavity 2 - 1.5mm wide) will show 3.5 volts on average on an active circuit. By disconnecting the battery does nothing. Saved favorite radio satiations are still saved on an electronic erasable programmable read-only-memory or (EEPROM) as these are used in almost every module. Re-connecting the battery most likely fixed a dirty-corroded cable and have system voltage, 13.2 volts hot to 14.6 volts hot. By disconnecting the battery (If it will run) you lost the opportunity to check and diagnose the root cause by seeing 12.6 volts at the alternator B+ & ground, then 12.7 volts the battery bolts on the side. If you had a (DVOM) with a Min-Max feature, set it to voltage, crank over, go back to the (DVOM) and see 9.8 volts. This maybe enough to start it be freaks out the electronics or produces 10.4 volts to the entire system while running. Even the shift display has an electric switch on the side, by hydraulic switch inside on the valve body of the 4L60e. Alternators produce direct current, get hot and change output depending on temperature. The lower the temp, the higher the charge. But is one of the 3 positive diodes or 3 negative diodes fail and leak voltage backwards, then A/C voltage goes out thru the entire DC system. This activity disrupted the 0-7 volt class-2 serial data signal, UART, Keyword 2000, Keyword 2001 or GM-LAN (Two wires, twisted 9 times per foot, 120 ohm termination resistors at end modules. 1 volt high & 1 volt low to offset high voltage induction and frequently foil covered and connected to ground.

Thanks so much, I had the Rear AC Blower running all the time and it would not switch off (Toyota Sequoia 2014), by doing the reset steps in the this video the problem is solved.... 🤩🤩🤩.
I just used this method on my 2005 Honda CR-V it worked like magic. I tried a Milwaukee impact, a Dewalt impact, my air impact, a long cheater on a breaker bar using the Honda tool (I broke the harmonic balancer doing this). First try using this method it came loose. Hooray!😅 Thank You.🎉
Why did the harmonic dampener break? I'm confused at what method you used and all the impact talk. Aren't we talking about discharging the systems after disconnecting the battery? I'm just trying to understand what you're talking about. I'm dealing with knock sensor code on 08 turbo acura rdx. You having an 05 crv I'm trying to figure out if this can help me with my problem.
@ The harmonic balancer is bolted in the end of the crankshaft. It helps mechanically balance the engine. It has no relationship to the electronic components of the engine (ECU).
I have had a hard time with my F150 replaced alot of stuff and it would keep going in limpbmode. . I saw your video today and tried it .Happy to report that it is working so far. Thank you.
My 2006 Ford focus PATS systems activated and would not turn over. I did this and it reset the system and started right up. Saved me from having to have a locksmith reprogram my system.
R u serious? My 2010 f150 went into Pat's lock 18 months ago and it sat in my backyard for 17 months I was fidlling around with some wiring under the dash and alligator clips and somehow magically got it too start drove it for a month perfect no problems at all then it goes back into security lockout mode once again and now I cannot get it going I'm going to try this in just a second and I'll let you know if it works I'm really optimistic after your comment fingers crossed
Had a issue with anti theft light blinking on then off along with gas,temp,battery and oil gauges dropping only when headlights are turned on. I watched this video how to reset All control modules on 2011 silverado pickup 5.3 here to tell you Problem Solved thank you for the video I've just subscribed.
A friend gave this a shot and not only did it reset the system as expected, his blinker fluid was also refreshed. Apparently there was also an extra muffler bearing in the exhaust system, because after resetting the entire system, including blinker fluid, a muffler bearing rolled out the tailpipe. Now it only makes 3/4 the noise it made before. Amazing!
Okay I was driving with a bad camshaft position sensor and the signal was so weak that the ECU turn off the fuel and spark. But once I replace the camshaft position sensor the fuel and spark is still off and my car still won't start. I did this and still won't start. You can't turn the fuel and spark back on once it has been turned off. I'm just going to have to replace the spark plugs again and I'm gonna have to replace the fuel pump. Bad camshaft sensor really messed up my car. Now that I have the new camshaft sensor my car still won't start.
@@BryanG830You might have got a bad sensor. I'd take it back and have it replaced. Before I put a new fuel pump in it. Because fuel and spark are both controlled by the computer. Sounds like the computer still isn't getting signal from the cam shaft sensor. And getting bad electronic parts happens all the time. Just a suggestion because I had the same issue with a Toyota Corolla. Replaced the cam sensor a second time and fixed it.
Ssangyong Rexton 290 2002 automatic, would not shift to 4th gear and would usually shift very ruffly otherwise. After doing the reset, as shown in the video, shifting to 4th is no longer an issue. Also it shifts like a dream between all the gears now. Thank you very much good Sir!
I took my car in garage after ignition switch and starter. I bought the reconditioned and programmed ECM from Flagstaff -- a company from New York ( priced at $176, but with exchange and shipping = $384)!!! I'm a dyi'er beyond my skill set. I took it to my mechanic who had a scanner, diagnostic technical knowhow, etc.
David W.- just sent my ECM back to Flagship One for reprogramming. How did they work out for you. Seemed like the BCM issues never reset. Your thoughts please....
as you said that more complicated cars you cannot dissconnect the battery, my question is don't they always dissconnet the battery on every vehicle when they weld the car to protect the battery, I am no pro at this but I am wondering how this works.
Always check if you can do this with your year/make/model. This has been a common thing to clear the KeepAlive memory, except for '96 Fords. '96 was their first year of OBDII. Doing this on that year, maybe '97 and '98 as I can't remember when they implemented the fix, will instantly fry the KeepAlive circuit thus needing an ECU replacement. They fixed the issue eventually in later years. As always, proceed at your own risk.
Have a 2003 Trailblazer EXT Northface Edition 195000 miles, 4.2L 4WD. Had an issue come up where I was losing MPG and power, wouldn't stay on cruise control. Took it to a mechanic in another town because it broke down on the highway, spent $80 for a sensor, no joy. Replaced battery, spark plugs, fuel filter, air filter, and had oil changed; still no joy. Towed it to my long time mechanic ($180 for 40 miles), learned catalytic converter was full. Had it replaced. Still not right. Seafoamed it in gas tank and cleaned throttle body, still engine stuttering and bad mileage. Watched this video, replaced plugs with Bosch plugs and followed directions to clear ECU memory. Took it out and drove it, 45MPH on cruise without any stuttering; 70 MPH, no stuttering; 55 MPH no stuttering and fuel economy is back to normal. Problem seems to be gone! If it is, saved me buying another ECU and having it programmed, probably $800 or more. Thank you!!!!

Almost all the calibrations in the Engine Control Module are written to the EEPROM meaning it has to be electronically erased. This is done with a scan tool. Clean the battery terminals with a small wire brush, a mix or paste of baking soda & water and use an old tooth brush. It is a chemical reaction between an acid and alkaline. Even a cola has citric acid so it can works on Cooper oxide, the part the turns green. Have the battery tested at you parts store. If you have / buy a digital volt ohm meter, then when running check the voltage level at the alt and move ground around to the fender, frame, block and battery negative. You are looking for a loss. Loss means a dirty, loose or corroded connection or broken. Remember that alternators produce the negative current off the back housing. 99% of the times, there is a threaded shallow hole on the back that allows a 10 gage or larger 6 gage wire & eyelets the from the alternator to the block, cylinder head or intake lowering resistance to the battery. Using "Star Washers" sold at home improvement stores sell internal & internal star washer that are effective on rusty, galvanized, painted or undercoating. But checking for voltage drop is alway done with engine on, lights, heater on high, wipers, stereo, just current flowing thru an active circuit to check. It works every time. An Engine Control Modular's had to sent out for basic reprogramming be it used or update to a restoration. Visit LT1Swap website because Brendan has a lot of offer as extremely reasonable prices. DK, Omaha.
@@philjagdon6774 I am not sure what trigger the immo. I recall jacking the front of the car, quite high, for some maintenance, maybe disconnecting the battery, and afterwards the car did not start.
On a modern car this could possible cause power spike in the capacitor causing more issue or even new issues including a fried ecu. You should always use a resistor inline between the negative and positive cables. 1ohm 10w resistor should take roughly 15min . You can use higher resistor but Higher resistors wil need to be connected longer

My 1999 456M GTA Ferrari has several separate ECUs. Will your method of resetting them work on my car or is the engine management system too complicated?
Hi and thanks for this detailed, informational, tutorial video. Do you think this will restore an 05 Chevy Silverado LS 1500 5.3 bad instrument cluster that works from time to time? TIA
Why did you remove/ isolate the positive from the battery in this video but left the positive connected to the battery in the other video with the Ford Explorer?? Is it different with the Chevy or does it matter?
After replacing the fuel pump in my Jeep grand cherokee laredo 3.7 WK- Im now having a problem with a vapor lock and my new pump is making a ringing/humming noise off and on-is there a way to fix it with a inline check valve or inline filter of some sort. I have to release pressure on the fuel rail to re-crank it after it runs for more than 20 minutes/ which is a possible fire risk.
Great video but Eid you have push button start like I do? I have a 2011 SRX that codes leading up to the timing belt won’t turn off, everything has been replaced including the timing belt. I don’t know if this would work but I’m desperate here.
Good man.... Will your brilliant system work on a landrover discovery 2024 T5 I do hope so, I have locking door problems... Cost a fortune so far to fix and has started to give trouble again..... 👍🙏
Would It be safe for me to do and get the stock/original tune back if the previous owner of my truck (2003 Sierra 1500 5.3l) took it to a shop and paid to have a custom "gas saver" tune put on it? and if so it would just revert my truck's tune back to stock right? Because that's the goal here since the tune on it now doesnt allow it to rev past 3k rpm in any gear when on a stock tune 1st and 2nd gear shift out at 52-5600rpm.. so the truck just feels gutless and I to revert back
I had a similar issue are the Dodge ram that the gas gauge and gauge is went nuts and it has a process to apparently these new cars have process is built into the ignition switch and they’re probably like Dealer fix all the items that they don’t give out those secrets, but this is obviously one of them because I followed another videos instructions for the Save guy to take and I was shocked that things were resetting everything was fine then. My friends car just blew this out of the eve vapp sensor and now it’s not going in and out and I think her problem was the main ground strap from the engine into the frame broke so this is how these things start bad connections you always want to make sure you clean everything anytime you’re working on any electrical stuff use the electrical connection grease if you have to to get a good ground. A broken ground out of gas take wire could really affect the gauge on Fords. I’ve had several that were the ground breaks it reads 3/4 of a tank of gas.
Awesome video 🙏🏽 I’ve ordered a remanufactured BMC flashed to my vin twice, and both times got a no start. I’ll probably have to perform this process to get it going, but now I’m wondering what will happen if I reset my original BCM 🤔 I’ve had my truck for 2 years and the horn never worked, and the same with the A/C. Recently the third brake light stopped working Since last summer my CEL would flash after about 3K rpms, it started idling rough, and had all types of codes. Replaced everything, cleaned all grounds, and now I’m down to the BCM, but I’m really wondering if this step will cure it of the random codes, cel flashing and everything else. THANKS!!!
Hello, I see you were looking at a video that you had a Cadillac SRX and you wanted to know if you could reset or disconnect the battery .? Did you ever do it and hopefully it worked out for you? I have an SRX too and I also would like to know

Might this work on my 2004 Corolla? It doesn’t start, all of a sudden, and I’ve replaced both O2 sensors, and the fuel pump. Air/ fuel mixture? Haven’t put a scanner on it yet
I have an 89 Dodge ram van 318 didn't really need to tune up but I did anyway in the 6 years time that I've known it it's never needed any work plugs wires cap rotor air filter immediately ran like shit. Check coil it was fine so replace fuel filter just recently found out that it may have the brain box. I've heard of disconnecting the cable watch the video and liked it my question is the tipm the same as the ECU is that the same as brain box? And what's the difference between a hard reset and a soft reset? Again the van is always drove by and it was our church van always had a tank of gas right now I run on here a lot and even ran out a couple times should I check the new fuel filter it's only been 2 weeks should I drop the gas tank and clean it? Not sure where to start and I know nothing about computers thank you
Would this work for a 2005 ford explore? I changed the battery and it went into safe mode. It starts but it won’t drive since it’s in safe mode. Thanks
Thanks good video. I was told to start the truck put the transmission in low or 1st gear for 3 minutes and 2nd then drive and reverse. Does it make a difference ?
Yeah. There’s a ridiculous number of relearn processes out there. Some work. Some don’t. It is highly dependent on the year and if it has an electronic throttle body or cable.

This is one of the best videos I’ve seen on this yet thank you. You may have just saved my friend having her 2008 GMC towed to the dealership.
Thank you . Thank you. Thank you. 2006 Silverado 2500hd battery change, then truck lost it’s mind. Followed this procedure, works better than ever!
What do you mean lost it’s mind
😅😂
I just used this method on my 2005 Honda CR-V it worked like magic. I tried a Milwaukee impact, a Dewalt impact, my air impact, a long cheater on a breaker bar using the Honda tool (I broke the harmonic balancer doing this). First try using this method it came loose. Hooray!😅 Thank You.🎉
Why did the harmonic dampener break? I'm confused at what method you used and all the impact talk. Aren't we talking about discharging the systems after disconnecting the battery? I'm just trying to understand what you're talking about. I'm dealing with knock sensor code on 08 turbo acura rdx. You having an 05 crv I'm trying to figure out if this can help me with my problem.
@ The harmonic balancer is bolted in the end of the crankshaft. It helps mechanically balance the engine. It has no relationship to the electronic components of the engine (ECU).
I have had a hard time with my F150 replaced alot of stuff and it would keep going in limpbmode. . I saw your video today and tried it .Happy to report that it is working so far. Thank you.
Work for my 1996 chev Tahoe ty I was fixing to buy new ecm man nice job
Hi could you tell me what problems you had before resetting? Thanks
HEY MAN WHATS UP. I APPRECIATE THE INFO HOMIE. I DIDNT KNOW TO DRAIN THE MAIN VEIN OF POWER TO RESET THE WHOLE SMACKAROO. GOOD ONE CHIVATO
My 2006 Ford focus PATS systems activated and would not turn over. I did this and it reset the system and started right up. Saved me from having to have a locksmith reprogram my system.
R u serious? My 2010 f150 went into Pat's lock 18 months ago and it sat in my backyard for 17 months I was fidlling around with some wiring under the dash and alligator clips and somehow magically got it too start drove it for a month perfect no problems at all then it goes back into security lockout mode once again and now I cannot get it going I'm going to try this in just a second and I'll let you know if it works I'm really optimistic after your comment fingers crossed
Had a issue with anti theft light blinking on then off along with gas,temp,battery and oil gauges dropping only when headlights are turned on. I watched this video how to reset All control modules on 2011 silverado pickup 5.3 here to tell you Problem Solved thank you for the video I've just subscribed.
A friend gave this a shot and not only did it reset the system as expected, his blinker fluid was also refreshed. Apparently there was also an extra muffler bearing in the exhaust system, because after resetting the entire system, including blinker fluid, a muffler bearing rolled out the tailpipe. Now it only makes 3/4 the noise it made before. Amazing!
😂😂😂
Those muffler bearings are a bitch
Blinker fluid and muffler bearings? Why do you want to mess with ppl
Interesting video. I just disconnect the negative terminal from the battery and then turn on the lights to clear out residual power.
Thanks for clearing that up 👍

Okay I was driving with a bad camshaft position sensor and the signal was so weak that the ECU turn off the fuel and spark. But once I replace the camshaft position sensor the fuel and spark is still off and my car still won't start. I did this and still won't start. You can't turn the fuel and spark back on once it has been turned off. I'm just going to have to replace the spark plugs again and I'm gonna have to replace the fuel pump. Bad camshaft sensor really messed up my car. Now that I have the new camshaft sensor my car still won't start.
@@BryanG830You might have got a bad sensor. I'd take it back and have it replaced. Before I put a new fuel pump in it. Because fuel and spark are both controlled by the computer. Sounds like the computer still isn't getting signal from the cam shaft sensor. And getting bad electronic parts happens all the time. Just a suggestion because I had the same issue with a Toyota Corolla. Replaced the cam sensor a second time and fixed it.
@@BryanG830 Try replacing your MAF sensor with a known good one.
Thank you very much young man if it wasn't for your video I wouldn't know what to do when my car wouldn't start, much appreciated.
Did this fix your no start issue?
@@vasilybk1760 only if you fix that actual issue at hand. Meaning whatever was causing the no start originally.
Ssangyong Rexton 290 2002 automatic, would not shift to 4th gear and would usually shift very ruffly otherwise.
After doing the reset, as shown in the video, shifting to 4th is no longer an issue. Also it shifts like a dream between all the gears now.
Thank you very much good Sir!
I took my car in garage after ignition switch and starter. I bought the reconditioned and programmed ECM from Flagstaff -- a company from New York ( priced at $176, but with exchange and shipping = $384)!!!
I'm a dyi'er beyond my skill set.
I took it to my mechanic who had a scanner, diagnostic technical knowhow, etc.
David W.- just sent my ECM back to Flagship One for reprogramming. How did they work out for you. Seemed like the BCM issues never reset. Your thoughts please....
@@jeremiahcannon4443
So far so good
Thanks!! Worked perfectly with a 2014 KIA Sorento!
as you said that more complicated cars you cannot dissconnect the battery, my question is don't they always dissconnet the battery on every vehicle when they weld the car to protect the battery, I am no pro at this but I am wondering how this works.
This was a big help for my 07 Expedition. TCM was acting up and a reset did the trick. Thank you for the video!
I followed your instructions and got my car inspected 😅 thanks alot
Always check if you can do this with your year/make/model. This has been a common thing to clear the KeepAlive memory, except for '96 Fords. '96 was their first year of OBDII. Doing this on that year, maybe '97 and '98 as I can't remember when they implemented the fix, will instantly fry the KeepAlive circuit thus needing an ECU replacement. They fixed the issue eventually in later years. As always, proceed at your own risk.
Thanks so much for sharing this method. I will perform thess same steps after replacing my throttle body.
Did it work, I cleaned my throttle body and now my Chevy idle is to high after I step on the gas ,
@@michaelgallo2723 on my ram when replacing mass air flow the manufacturer said to cycle throttle 5 times to the floor with ignition in Acc mode
@@michaelgallo2723 ppl never put their end results for us all to share. Sad, but true. Hope you fixed your issue.
Have a 2003 Trailblazer EXT Northface Edition 195000 miles, 4.2L 4WD. Had an issue come up where I was losing MPG and power, wouldn't stay on cruise control. Took it to a mechanic in another town because it broke down on the highway, spent $80 for a sensor, no joy. Replaced battery, spark plugs, fuel filter, air filter, and had oil changed; still no joy. Towed it to my long time mechanic ($180 for 40 miles), learned catalytic converter was full. Had it replaced. Still not right. Seafoamed it in gas tank and cleaned throttle body, still engine stuttering and bad mileage. Watched this video, replaced plugs with Bosch plugs and followed directions to clear ECU memory. Took it out and drove it, 45MPH on cruise without any stuttering; 70 MPH, no stuttering; 55 MPH no stuttering and fuel economy is back to normal. Problem seems to be gone! If it is, saved me buying another ECU and having it programmed, probably $800 or more. Thank you!!!!
Very cool. Congrats! And what a headache!

Does this reprogram the body control module???
Everything
I've done this before and I think it really works,I have a 2001 vw Jetta by the way 👍👍
you are not sure if it works ??
Does this affect Recalibration done on the ECU?
Almost all the calibrations in the Engine Control Module are written to the EEPROM meaning it has to be electronically erased. This is done with a scan tool.
Clean the battery terminals with a small wire brush, a mix or paste of baking soda & water and use an old tooth brush. It is a chemical reaction between an acid and alkaline. Even a cola has citric acid so it can works on Cooper oxide, the part the turns green. Have the battery tested at you parts store. If you have / buy a digital volt ohm meter, then when running check the voltage level at the alt and move ground around to the fender, frame, block and battery negative. You are looking for a loss. Loss means a dirty, loose or corroded connection or broken. Remember that alternators produce the negative current off the back housing. 99% of the times, there is a threaded shallow hole on the back that allows a 10 gage or larger 6 gage wire & eyelets the from the alternator to the block, cylinder head or intake lowering resistance to the battery. Using "Star Washers" sold at home improvement stores sell internal & internal star washer that are effective on rusty, galvanized, painted or undercoating. But checking for voltage drop is alway done with engine on, lights, heater on high, wipers, stereo, just current flowing thru an active circuit to check. It works every time.
An Engine Control Modular's had to sent out for basic reprogramming be it used or update to a restoration. Visit LT1Swap website because Brendan has a lot of offer as extremely reasonable prices. DK, Omaha.
@@deankay4434 Thank you
I have no check engine lights but can’t smog because of modules not being cleared. Will this clear them? 08 wrangler JK manual transmission
Will this reprogram the ecm?
SX4 stuck by the immobilizer. This did the trick. Thanks so much.
Hello what were the problems in the first place before you reset?
@@philjagdon6774 I am not sure what trigger the immo. I recall jacking the front of the car, quite high, for some maintenance, maybe disconnecting the battery, and afterwards the car did not start.
On a modern car this could possible cause power spike in the capacitor causing more issue or even new issues including a fried ecu. You should always use a resistor inline between the negative and positive cables. 1ohm 10w resistor should take roughly 15min . You can use higher resistor but Higher resistors wil need to be connected longer
My Mazda 5 2010 diesel have suddenly lost the Bluetooth - option does mot appeare when pushing on the phone knob. - mute - appeares instead
Anyone know procedure for resetting?
where do you pick one of them up at?
Usualy when i push the phone-button the i car phone system starts asking if wsnt to make a call, reg a New phone, etc - and when someone calls me while i my car i hear 'incomming call' i push the button and anser the call over the loadsystem..
My obd2 also get No contact with the car.
After disconnecting the battery, turn on the headlight to dissipate the capacitors.
A little advice please 08 Chevy express 2500 w/4.8 V8, cleaned the throttle body, I didn't realize what was gonna happen, ya think your method will get my idle back where it belongs?? I see alotta people reaching out, I feel like the interior of the truck looked Similar, just not sure if it'll help this issue, please 💯
Question? Can I use any jumper cable because I see the one you are using in the video does not have a negative end? My car is a 2010 Chevy traverse.
I know your comment is a month old but future reference. Yes You can use regular jumper cables ,but only use the negative cables on them.
@@lindswill4144 can you explain what you mean by this?
@@avinaftali8595 use the black ones only
There is a black side and a red side… only use one color fit both so either both red or black . Make sense?
Is this idea effective for Hyundai accent 2017 model. Gasoline?
Thanks so mucho for greate information...i fixed a Ford escape 2012 with this process.
My 1999 456M GTA Ferrari has several separate ECUs. Will your method of resetting them work on my car or is the engine management system too complicated?
What single jumper cable you using. I have regular jumper cable two positives and negatives
Just use the neg. One dumb ass can’t you see.
.
When you connect the jumper cables is it to the cables that were connected to the battery?
Hi and thanks for this detailed, informational, tutorial video. Do you think this will restore an 05 Chevy Silverado LS 1500 5.3 bad instrument cluster that works from time to time? TIA
Why did you remove/ isolate the positive from the battery in this video but left the positive connected to the battery in the other video with the Ford Explorer?? Is it different with the Chevy or does it matter?
Will this work on a 2012 VW Beetle Turbo?
Will this work on a newer tuned and deleted diesel truck if you do it with both batteries in order to get out of limp mode?
what type of jumper cables are u using? i aint ever seen cables with just 2 ends
Right???🤣🤣🤣
After replacing the fuel pump in my Jeep grand cherokee laredo 3.7 WK- Im now having a problem with a vapor lock and my new pump is making a ringing/humming noise off and on-is there a way to fix it with a inline check valve or inline filter of some sort. I have to release pressure on the fuel rail to re-crank it after it runs for more than 20 minutes/ which is a possible fire risk.
Great video but Eid you have push button start like I do?
I have a 2011 SRX that codes leading up to the timing belt won’t turn off, everything has been replaced including the timing belt. I don’t know if this would work but I’m desperate here.
Very clear tutorial. Thanks
Good man.... Will your brilliant system work on a landrover discovery 2024 T5 I do hope so, I have locking door problems... Cost a fortune so far to fix and has started to give trouble again..... 👍🙏
2024??? Isn't it under warranty??
Would It be safe for me to do and get the stock/original tune back if the previous owner of my truck (2003 Sierra 1500 5.3l) took it to a shop and paid to have a custom "gas saver" tune put on it? and if so it would just revert my truck's tune back to stock right?
Because that's the goal here since the tune on it now doesnt allow it to rev past 3k rpm in any gear when on a stock tune 1st and 2nd gear shift out at 52-5600rpm.. so the truck just feels gutless and I to revert back
Will this work to relearn my crankshaft position sensor after I replace it?
no.
Can we direct disconnect negative sensor terminal for other task ? May it damage or create problems in ecm?
Does it work with Subaru legacy b4?
Will this method benefit me on my 2008 Suzuki XL7?
I had a similar issue are the Dodge ram that the gas gauge and gauge is went nuts and it has a process to apparently these new cars have process is built into the ignition switch and they’re probably like Dealer fix all the items that they don’t give out those secrets, but this is obviously one of them because I followed another videos instructions for the Save guy to take and I was shocked that things were resetting everything was fine then. My friends car just blew this out of the eve vapp sensor and now it’s not going in and out and I think her problem was the main ground strap from the engine into the frame broke so this is how these things start bad connections you always want to make sure you clean everything anytime you’re working on any electrical stuff use the electrical connection grease if you have to to get a good ground. A broken ground out of gas take wire could really affect the gauge on Fords. I’ve had several that were the ground breaks it reads 3/4 of a tank of gas.
Awesome video 🙏🏽
I’ve ordered a remanufactured BMC flashed to my vin twice, and both times got a no start. I’ll probably have to perform this process to get it going, but now I’m wondering what will happen if I reset my original BCM 🤔
I’ve had my truck for 2 years and the horn never worked, and the same with the A/C. Recently the third brake light stopped working
Since last summer my CEL would flash after about 3K rpms, it started idling rough, and had all types of codes.
Replaced everything, cleaned all grounds, and now I’m down to the BCM, but I’m really wondering if this step will cure it of the random codes, cel flashing and everything else.
THANKS!!!
It’s okay to put a red cable
clamp on the black terminal clamp?
It is if they are disconnected from the battery
Thanks man!! does this procedure also serve the Toyota Tacoma or 4runner 2nd gen?
Thank you. This got my truck back on the road. Great informative video.

So I just have a question would this work on any vehicle? I have a 2009 Cadillac SRX wanting to try this also
Hello, I see you were looking at a video that you had a Cadillac SRX and you wanted to know if you could reset or disconnect the battery .? Did you ever do it and hopefully it worked out for you? I have an SRX too and I also would like to know
Absolute life saver.
Could the same be possible for a crank no start on 2015 Chevy v6 direct injection impala new body style
If you want to go a step further, with both battery terminals DISCONNECTED, turn the key on and then off once.
What does that step do for you?
That's a good 1, open the circuits. Like a 2 way switch.
You mean turn it on then disconnect the battery and turn off the key ? Thanks
@@philjagdon6774 Read it again.

Does Your horn, cruise control work. It might be your airbag clock spring broken
Thanks for the great video!! I did exactly what you said, but I left them connected with the cables for a few hours. It didn't reset anything in the car. Any idea why, or how I can do it? Thanks for the help I appreciate it.
Thanks for the great info, is it safe to perform this on a 2014 Toyota Sienna van? Thanks
I would think it’s safe on a Toyota.
Hi is it safe to do it on a 2015 chrysler 200C?
@Robbie Farmer the fact your actually asking about something being safe on a Mopar product is funny beings there is no safe about a dodge 🤣 😂 😆
He said make sure thst it is not a vehicle yhst the power can't be taken off of.
Might this work on my 2004 Corolla? It doesn’t start, all of a sudden, and I’ve replaced both O2 sensors, and the fuel pump. Air/ fuel mixture? Haven’t put a scanner on it yet
Would that work for a 97 Ford explorer XLT four-wheel drive? Another question I have is why would my cigarette lighter fuse be blowing?
I have an 89 Dodge ram van 318 didn't really need to tune up but I did anyway in the 6 years time that I've known it it's never needed any work plugs wires cap rotor air filter immediately ran like shit. Check coil it was fine so replace fuel filter just recently found out that it may have the brain box. I've heard of disconnecting the cable watch the video and liked it my question is the tipm the same as the ECU is that the same as brain box? And what's the difference between a hard reset and a soft reset? Again the van is always drove by and it was our church van always had a tank of gas right now I run on here a lot and even ran out a couple times should I check the new fuel filter it's only been 2 weeks should I drop the gas tank and clean it? Not sure where to start and I know nothing about computers thank you
What did you do hook the cable to the positive an a ground
Would this work for a 2005 ford explore? I changed the battery and it went into safe mode. It starts but it won’t drive since it’s in safe mode. Thanks
Can u use regular black and red jumper cables to do this???
Thanks good video. I was told to start the truck put the transmission in low or 1st gear for 3 minutes and 2nd then drive and reverse. Does it make a difference ?
Yeah. There’s a ridiculous number of relearn processes out there. Some work. Some don’t. It is highly dependent on the year and if it has an electronic throttle body or cable.
I only have a battery jumper cable type module. not regular jump cables...can I still do this with that?
Yes just make sure you use the same color cables when draining the system
Will this work on a 2008 pontiac g8 gt?
Wow man YOU ROCK THANKS FOR SHARING!
This really works. But, it is only meant to reset the ECU only after the problem has been rectified.
My compass out which controls the ac. I’m assume they on the same circuit. Will this method help?
Sounds like maybe coolant temp sensor it will make it to where your AC will not come on
This is a nice tip, however I have a problem with my car. The dash board has no power as well all the body control function are not working but there's a power going to fuse box under the dash board from the key switch. Can you help me what is my next step?
Wht are u conneting the cable to? I cnt tell are u connecting it to the negativel cable?
Hi im Robert.I just wanna to ask u ,if this reset works for Mazda 323 FBa 1998 .1,5 16V 88ps.
thank u for your request.
I noticed you did not use regular jumping cables. Use some other kind now will it Work with regular jumping cables.
Does this work for all vehicles no matter year , make , model
No not t all vehicles
Can you do this with a push start or no?
Does this apply to a 98 chevy Z71 vortex 5.7 cause I'm having all kind of elect problems with it as far as with it running...and nobody can tell me ..I just put in another motor new distributor and cap wires sensors and plugs and nothing has stopped the many strange things its doing ..3 alt 3 battery's 4 starters and its also starts discharging after it runs a while I NEED HELP PLEASE ....BAD ..
