Every time Eric O says, "Im not much of a network guy," he then proceeds to demonstrate an excellent working knowledge of CAN BUS and then solves the problem very efficiently. Nice work, Mr. O!
@@OcRefrig Me and my boy were doing a brake job last week, we had his girlfriends car on the lift doing a torque converter in it, so we did the brakes on the floor. Me, I can squat down like a catcher and do brakes. He complained about being all hunched over like a caveman. Of course I'm 5'9" he's 6'. LOL!! I am also near 60 years old. ;)
in a previous life, lawn mower man, was a goldfish....... god is coming back, you won the lottery, your wife left, the moon is going to hit earth, cancer has been cured, . hmmm, lawn needs mowing,,,,
DIY action? That would be a dream location. Creeper. Concrete floor. Roof over the vehicle. My usual DIY work place is gravel, outside in the sun/rain, snow, sleet, mud, on a piece of cardboard. :) Love ya.
Years back a person came in with a car for what I do not remember, tune up, something simple. After whatever work we did, we took it for a test drive and noticed the 3 speed automatic transmission was not shifting into second gear, but, shifting from first directly to third. When we informed the customer, they flipped out, blew a gasket and screamed and yelled that we caused the issue and we will be repairing it for free. The customer took their car for a ride, came back, and said it's working normally, what do you mean, it's fine? We said OH! your right, have a nice day, see ya later. They drove away happy.
An excellent example of how to do a proper diagnosis. Right at the beginning, before even plugging in the scan tool, you suspected the differential control module, but still did some thorough testing to confirm your suspicion.
Mr. Eric, Just another example of your diagnostic skills or ability or whatever you want to call it. I have as much chance with electronics or anything electrical related as a fart in a tornado. So in all honesty I watch these just to see how you go about things. No clue at all. That and your humor keep me coming back on these. Unfortunately, every damn thing on vehicles today are ALL electronic. I'm just outta luck. Keep 'em going and I'll keep watching. 😊😊
I LOVE that closing. Ever. Single. Time. Eric O says that, I think, "That is correct. I know nothing about fixing cars, but I am *sure* that after I buy $543,987 worth of tools, and a $1,135,680 shop with two lift bays, and an alignment rack, I too will be able to fix my car juat Like Eric."
"I don't Speak Creeper" LMAO you are too funny Eric and if I had a lift I would lose that ability pronto as well. Great video as always especially when in unfamiliar territory.
Oh my goodness, you were serious about lawn mower man cutting his grass 3 tines a week! Great job doing "not a network guy" stuff in the middle of an electrical blackout! I'm impressed more with every episode of SMA! Thanks Eric!
Honestly, watching SMA videos is just plain ol entertaining. Great banter, hilarious one-liners, and real, hands-on knowledge to back it all up and teach me something new every video. I love watching, I try to put all the knowledge/tips given to use every day. Seriously, hats off to you Eric. Keep it up.
Hi, Eric, I am a GM Technician in Halifax Canada, and I have had two same symptom vehicles and I think they were 2018 Encore. and it was just bad battery. After battery replacement, it became normal, and there is a code for the rear differential and I had to recalibrate the rear diff for clearing the code. There is a unique number for the calibration under the differential 1 digit (Probably from 1 to 9). After replacing the battery and calibrating the rear diff, no more issue. One thing I found is... when I tried to start with booster, the EBCM data shows brake pedal is not pushed even if I pushed the brake pedal, that's why it did not start with booster. However, after battery replacement, it became normal. When we disconnect the battery, it is actually performing global reset, and everything is back to normal, but only rear diff calibration infomation is deleted.(I don't know why, but it is not difficult to calibrate it as long as we know the calibration number. (The number is just near the module, I think it was front left. about 1/2 inch big. Please read GM Service information for this)
Interesting. At any rate I just follow facts. The fact is this rear diff clutch module has a whole rotted through it and is full of corrosion. A battery is not going to fix this one. And you're right, when replacing the rear diff module, you have to write the diff code number one through nine.
My creeper was a small shopping cart left in the ditch by my home. I cut the top half of the cart off leaving just the wheeled bottom, put a piece of 3/8 plywood on it and WALLAH I had a very maneuverable creeper. Had it a long time, a friend borrowed it, then found out a year later he moved and took it with him !!!!!
Great video. Thanks. That diff module is connected as we would call in the fire alarm world. “Tee tapped”. GM just loves those expensive underbody modules
I have been following Eric since 2017 and this is the FIRST time I have seen him use a creeper. He had that car up on jackstands; looks like me in my shop. Eric says there are guys that can look at a wave form and tell you what color underwear you have on, but he can't do that. Well, I believe he can do it as well. His modesty prevents him from stating the obvious. GREAT VIDEO!
My granfather is a certifird Buick repairman, and he suggests the fillowing: Make sure that the two sperving bearings are in a direct line with the panometric pam. That way, side fumbling will be prevented. Also make sure that the main winding is properly being used in the operation of nofer tremlems. That way, wenever a fluorescent score motion is required, it may also be employed in conjunction with a drawn reciprocation ding alarm to reduce sinus-socal depleneration.
ONE nice thing about GMLAN that the COMM Lines go into and out of a module is you can UNPLUGIT and bypass the module by shorting the CANL PINs & then CANH PINs together to remove a possible bad module from the system for diagnosis. I first learned this on the 15th Street Channel, then the channel went away and it seems back up again OMG. At 15:05 when you check CAN COMM again, you ought to zoom in on the Packet more as typically you can see added resistance in the waveform in the form of slanted horizontal lines, there are a couple of types of resistance but for a connector with some corrosion is typically noticeable right away as a small amount of interference in the horizontal line sections. As your training continues, keep an eye on these slants to get a better feel for the malfunction once found. I did not pay close attention to try to figure this out from your video but initially, you need to make a list of what modules are not online, look at the schematic to see how those modules are tied together, and then make a deduction of where the bad module or connector or broken wire might be located. ONLY A GUESS but you had a good module at the top of CANC (SAS where is it on the schematic?) and the others were offline, maybe the problem is at the outlet of that good module on the CAN Schematic or very near? Most of the circuitry is in SERIES with a couple offshoots based on RPOs. As we already know, one of the CONS of a TOPOLOGY is it does not show the actual orientation of the module relative to the others, series or parallel, this is why the schematic is really useful. Let's see what Part 2 holds. Thanks for all your videos.
I loved the way you were able to seamlessly shift from topology to the scope and even the resistance check on the network with a few clicks. Dang, scan tool envy, again....
I love his little asides, such as 'Doing it Amish style' when the power is out, and he has to jack up the vehicle and use the crawler to inspect the underside.
The moment i saw that it was a CAN network problem, I knew straight away that it was the AWD control module. Fixed a heap of them while I worked at Vauxhall.
A corrosive area and "of course we'll put the module under the vehicle!" Didn't do network repair prior to April 2016, so I've learned a lot from you and Ivan. OEM's need to learn a lot more leaving the vehicle owner stranded cause the rear diff module took the network down! No quality in that... BUICK! Good one Mr. O. On to part 2.
If you close the latch in the door, you can stop the door ding with the ignition on. Just don't forget to open it by pulling the door handle will lifting the latch with you finger before you close the door. If you don't you'll get a load bang when it hits the striker.
Eric this reminds me of when I had a faulty differential module (DEM) on my 2003 Volvo XC90. It wasn't working and there were a couple of fault codes (no communication from the ABS & CEM to the DEM) so I just lived with it because the rest of the car was fine. I just had no AWD (all wheel drive). I started to have electrical problems which pointed to a faulty CEM (Volvo's gateway module) so I took it to a specialist who suggested getting the DEM repaired first so I sent the DEM off to be repaired to be told that it was beyond repair so I had to get a reconditioned DEM. Once that was fitted, I had a fully working AWD but I was still having the electrical problems so back it went to the specialist who couldn't find anything wrong with the CEM so I got them to remove the CEM and I sent it off for repair. I took the repaired CEM back to the specialist who refitted it and it has been fine ever since.
Another great class with SMA on network connections and communications. My 16 malibu had the same power steering msg when it was a few months old. Took it to the dealer and they did an update and it was fixed. Never came back again.
Eric, thanks for the good video. You are correct - "409" (the song) was by the Beach Boys; "409" the car was a Chevrolet - Chevy put a truck engine with 409 cubic inch displacement (6.7 liters) in the Impala sedan. Loads of torque, great for drag racing.
Add a resistor to the network through the break out box is a good idea to try to see if the network will respond. Makes sense to add one temporarily if the OEM is open.
Thank you for another educational video on how the modules in newer vehicles are interconnected and how to break the system down to determine the problem area. My guess on the Power Steering being disabled is that it has to do with the lack of communication with the offending module - something in the software protocol is causing the power steering to be disabled because the power steering module cannot determine some information it requires to operate safely - engine speed, 2 wheel or 4 wheel drive or ?? Encountered a similar problem on a 2017 Chevrolet Impala that had an open circuit fault code for the left rear speed sensor because the ABS sensor wire was sliced where it went along the left rear trailing arm (no idea how it happened). Car worked fine when I parked it on a Wednesday night but on Saturday afternoon when I started it next got several messages and traction control light was illuminated. Messages were ABS disabled, Service Traction Control (along with a couple of lights on the dash being on), Power Steering disabled and also noticed the park assist light on the park assist switch was not illuminated like it normally would be. Found the sliced wire and repaired and was able to clear the code for the ABS open circuit fault and drove the vehicle a short distance to verify the repair. On startup after the repair the messages disappeared, power steering worked and the park assist light was illuminated again and was then able to clear those codes. Checked service data and could not find any mention of the power steering being disabled or the park assist feature not working with the ABS sensor open circuit code being present but did find mention of it happening in a couple of online forums. The logic on the power steering was that the Impala had variable ratio power steering and since the power steering module could not determine the speed of all four wheels the software protocol dictated that the power steering should be disabled as a safety precaution to prevent over correction at higher speeds - never did find any logical reason to disable the park assist feature - one of those GM things I guess. Look forward to watching part two.
Thanks for sharing this I have a '21 GMC Sierra 1500, and the faults you mentioned are almost identical to my issues, I'm 62 and a retired auto tech slightly handicap now, but doggone it I'm gonna have to get my old butt down there and have a good looksee, lol 😂
When you said that rear clutch module was giving you flash backs for a want of a better term I got the old blinkers on & was thinking if Mr O has had a vehicle with issues in that module before he is most likely on the right road. That is how much you get in my head .🤣
That was very informative, I own this same model car and we have experienced similar issues these vehicles are toilets ! Thanks for taking us along its really great to learn.
A friend of mine, recently became a widow. She asked me to look over a used Encore she thought was cute. I did not go look at it and told her I would not have any part in anyone buying one of those abominations. Today she bought a used Accord, with my blessing.
@@richardabner9420 Both I and the commenter I replied to used "one of those" - I for sure meant Buick Encore, and I think TargaWheels did too. Some of them are called Chevrolet Trax, and they are just as bad.
Something nice about fixing something that was working and now isn't means you don't have to fully understand why it's broke. In these faulty network videos you don't need to get a CAN packet analyzer, try to decode the data, etc. It doesn't matter how bad that diff module is broke... it's broke! I'd say this is the difference between a vehicle network technician, and a vehicle network engineer. And you're doing a great job of being a tech!
I just love watching you reason out the issues on your customer's cars. As a retired tech, electrical issues were NOT my strong point, so I appreciate your methodical diagnosis. I can also relate to the "flying lessons" your computer was about to get when it wouldn't do what you wanted!!! Does lawnmower man's lawn look as good as it sounds??? Keep up the good work, and I hope your customers appreciate what you do for them. Thanks!
Gotta love the boooick’s and the ford, & stelantis gems that keep the talented Mr. O and his beautiful wife Mrs. O, in business to support the fam!! I Always learn something from Eric’s videos and always get a laugh or three as well. Excellent work once again brother!! God bless~
i totally agree with your knowledge, being able to work through these. why do engineers have to make the car so complicated. it's not needed for anything except the bottom line.
Eric O's approach on how to tackle a case like this can really inspire a DIY mechanic even with mobility issues as myself, lol, I'm gonna try this method with my 2021 GMC Sierra 1500 low power steering issues money light on, 😉👍🏾
I watched this whole video and still don't know how you did it but am amazed just the same. Please move to Rhode Island. You'll have more work than you ever had before.
When im working on my own junk or some else junk. I try to be very careful of the connectors. I just finished working on my grand daughter Charger 3.6, replaced all 4 cams, lifters and Rocker arms. I had to wait for parts after i diagnosed the problems. It was a new learning experience for me. If I can do it, so can you approach Eric. Then the much anticipated start, rattled for 3 seconds and quieted down. Car runs smooth. Next is the fuel pump module replacement. Seems the gas tank is 1/4 tank, a low fuel level circuit code is on. No sweat, onto the next task.
Eric, I wanted to let you know that I had a 2017 Camaro and the Service Power Steering warning came up quite often. Along with that, I also did lose power steering. I had to pull over, turn the car off and back on and all was fine. Unfortunately, I don’t remember what the dealer did to fix it. It was under warranty at the time and taken care of. Point is, this problem seems to be a common issue with many GM products from that time era.
Some of the horror stories I could tell after being in business as a machine shop and decided I would work on cars also. While I helped a lot of folks, but, there were the ones...... Met some great folks there also. Did mostly engine and transmission rebuilds.
Check if it has side blind zone , modules in rear might be bringing the high-speed down if I remember, right, ya leave it up to Gm to put modules under the vehicle
Yes, a great spot. Right where the rear tires kick up all the water, mud, salt and anything else that will damage the sensors. I have had to replace several of them on my 2014 Impala. Other than those I like the car.
Not only does the salt on the roads destroy the frames of these vehicles, it takes out communications with the plethora of micro processors and your vehicle will not start. The definition of insanity. Eric's solid acumen aside, this is a pain in the ass and a unnecessary expense for the poor house wife who needs to take her gaggle of children to soccer games. Yeah, life became very complicated and distracting with micro processors: and all by design. We are living in the last days days, we should be frying bigger fish

Once that was fitted, I had a fully working AWD but I was still having the electrical problems so back it went to the specialist who couldn't find anything wrong with the CEM so I got them to remove the CEM and I sent it off for repair. I took the repaired CEM back to the specialist who refitted it and it has been fine ever since.
My 2017 encore started doing this yesterday!!!! Thanks for the vid hopefully this is my issue and not something more expensive
Dr O working on another fine GM product bravo sir
Another great class with SMA on network connections and communications.
My 16 malibu had the same power steering msg when it was a few months old. Took it to the dealer and they did an update and it was fixed. Never came back again.
Eric, thanks for the good video. You are correct - "409" (the song) was by the Beach Boys; "409" the car was a Chevrolet - Chevy put a truck engine with 409 cubic inch displacement (6.7 liters) in the Impala sedan. Loads of torque, great for drag racing.
Dude. You are such a skilled mechanic and entertaining/witty.
Rare combo
Hey Eric O, Been a regular follower for a long time and grateful for anything you're willing to share with us. Two thumbs up.
Awesome! Thank you!
X112... That takes me back to West Germany, late 80's, Army days. lol. Super stuff it was!
Add a resistor to the network through the break out box is a good idea to try to see if the network will respond. Makes sense to add one temporarily if the OEM is open.
Thank you for another educational video on how the modules in newer vehicles are interconnected and how to break the system down to determine the problem area. My guess on the Power Steering being disabled is that it has to do with the lack of communication with the offending module - something in the software protocol is causing the power steering to be disabled because the power steering module cannot determine some information it requires to operate safely - engine speed, 2 wheel or 4 wheel drive or ?? Encountered a similar problem on a 2017 Chevrolet Impala that had an open circuit fault code for the left rear speed sensor because the ABS sensor wire was sliced where it went along the left rear trailing arm (no idea how it happened). Car worked fine when I parked it on a Wednesday night but on Saturday afternoon when I started it next got several messages and traction control light was illuminated. Messages were ABS disabled, Service Traction Control (along with a couple of lights on the dash being on), Power Steering disabled and also noticed the park assist light on the park assist switch was not illuminated like it normally would be. Found the sliced wire and repaired and was able to clear the code for the ABS open circuit fault and drove the vehicle a short distance to verify the repair. On startup after the repair the messages disappeared, power steering worked and the park assist light was illuminated again and was then able to clear those codes. Checked service data and could not find any mention of the power steering being disabled or the park assist feature not working with the ABS sensor open circuit code being present but did find mention of it happening in a couple of online forums. The logic on the power steering was that the Impala had variable ratio power steering and since the power steering module could not determine the speed of all four wheels the software protocol dictated that the power steering should be disabled as a safety precaution to prevent over correction at higher speeds - never did find any logical reason to disable the park assist feature - one of those GM things I guess.
Look forward to watching part two.
Thanks for sharing this I have a '21 GMC Sierra 1500, and the faults you mentioned are almost identical to my issues, I'm 62 and a retired auto tech slightly handicap now, but doggone it I'm gonna have to get my old butt down there and have a good looksee, lol 😂
Eric going the extra mile with the creeper footage with some simon and carfunkel as a bonus!
One very good lesson on can bus systems. Thank you.
Always loved the great analysis theory and presentation to take you right to the problem
I am blown away. I have the same Autel and struggle with it. You make it soo easy. Your the greatest. 😂
When you said that rear clutch module was giving you flash backs for a want of a better term I got the old blinkers on & was thinking if Mr O has had a vehicle with issues in that module before he is most likely on the right road. That is how much you get in my head .🤣
Four wheel peel or two tire fire 😂 I love the terms you have for certain things lol
That was very informative, I own this same model car and we have experienced similar issues these vehicles are toilets ! Thanks for taking us along its really great to learn.
Yes! Multiple Eric O videos, it's a good day!
Agreed!!!!!🎉
Unfortunately not for me
Braggy bragerson. Lol
I hope the customer listens to you. ❤❤
Wow what a pile. My nephew almost bought one of those. I was glad he didn't a couple months ago, and I'm even more glad now.
A friend of mine, recently became a widow. She asked me to look over a used Encore she thought was cute. I did not go look at it and told her I would not have any part in anyone buying one of those abominations. Today she bought a used Accord, with my blessing.
“one of those”, one of those what?
car? creeper? Autel?
@@richardabner9420 Both I and the commenter I replied to used "one of those" - I for sure meant Buick Encore, and I think TargaWheels did too. Some of them are called Chevrolet Trax, and they are just as bad.
Thank you, for your explaination 😀
“I don’t speak creeper…” a classic, Eric! At 72, I not only don’t speak creeper anymore, I only occasionally speak “on my knees”, or “under the dash”.
Love to watch you work, great video Eric.
Excellent diagnosis and presentation as always
Something nice about fixing something that was working and now isn't means you don't have to fully understand why it's broke. In these faulty network videos you don't need to get a CAN packet analyzer, try to decode the data, etc. It doesn't matter how bad that diff module is broke... it's broke!
I'd say this is the difference between a vehicle network technician, and a vehicle network engineer. And you're doing a great job of being a tech!
Fantastic video showing us how to break down the system! Thank you
Great network diagnosis.
I just love watching you reason out the issues on your customer's cars. As a retired tech, electrical issues were NOT my strong point, so I appreciate your methodical diagnosis. I can also relate to the "flying lessons" your computer was about to get when it wouldn't do what you wanted!!!
Does lawnmower man's lawn look as good as it sounds??? Keep up the good work, and I hope your customers appreciate what you do for them. Thanks!
Thank you for all your effort and your great sense of humor . Brightens up my day, You can do no wrong.
Amazed at your process for deduction
...Actually, we know you got the job, 'cos we see the link for Part 2 there. 😁
@21:35 "Oh, you're about to get some flyin' lessons"........ 🤣🤣🤣 I'ma remember and use that one!!
Gotta love the boooick’s and the ford, & stelantis gems that keep the talented Mr. O and his beautiful wife Mrs. O, in business to support the fam!!
I Always learn something from Eric’s videos and always get a laugh or three as well. Excellent work once again brother!!
God bless~
Eric I love the way you think. ❤
i totally agree with your knowledge, being able to work through these. why do engineers have to make the car so complicated. it's not needed for anything except the bottom line.
That turbo soundfx is top notch :)
I have one of these, but here in Norway its called Opel Mokka, a 1.6 gas. Really nice cars in my opinion, low fuel consumption. Mostly easy to fix.
I think in Norway, you get a 1.6 petrol, not a 1.6 gas 😀
@@riaanlouw1874yes probably
Eric O's approach on how to tackle a case like this can really inspire a DIY mechanic even with mobility issues as myself, lol, I'm gonna try this method with my 2021 GMC Sierra 1500 low power steering issues money light on, 😉👍🏾
Looks like lot of these CAN bus issues are corrosion related. Great work.
I watched this whole video and still don't know how you did it but am amazed just the same. Please move to Rhode Island. You'll have more work than you ever had before.
he cant move to RI, that’s where Scotty K has one of his two homes and lives there.
The turbo noises…love it.
another great diagnostic video!
When im working on my own junk or some else junk. I try to be very careful of the connectors. I just finished working on my grand daughter Charger 3.6, replaced all 4 cams, lifters and Rocker arms. I had to wait for parts after i diagnosed the problems.
It was a new learning experience for me.
If I can do it, so can you approach Eric.
Then the much anticipated start, rattled for 3 seconds and quieted down. Car runs smooth.
Next is the fuel pump module replacement.
Seems the gas tank is 1/4 tank, a low fuel level circuit code is on. No sweat, onto the next task.
can you believe this fella, has a lift and uses the creeper. 🤣🤣🤣🤣🤣
couldn't resist poking fun.
Fantastic problem solving here, thank you for the video 👍
Eric, I wanted to let you know that I had a 2017 Camaro and the Service Power Steering warning came up quite often. Along with that, I also did lose power steering. I had to pull over, turn the car off and back on and all was fine. Unfortunately, I don’t remember what the dealer did to fix it. It was under warranty at the time and taken care of. Point is, this problem seems to be a common issue with many GM products from that time era.
Some of the horror stories I could tell after being in business as a machine shop and decided I would work on cars also. While I helped a lot of folks, but, there were the ones...... Met some great folks there also. Did mostly engine and transmission rebuilds.
Check if it has side blind zone , modules in rear might be bringing the high-speed down if I remember, right, ya leave it up to Gm to put modules under the vehicle
Yes, a great spot. Right where the rear tires kick up all the water, mud, salt and anything else that will damage the sensors. I have had to replace several of them on my 2014 Impala. Other than those I like the car.
The power was out, but at least that guy stopped mowing his lawn😂
This video is a good example of what happens when you combine shoddy workmanship with too much electronics in a vehicle.
Not only does the salt on the roads destroy the frames of these vehicles, it takes out communications with the plethora of micro processors and your vehicle will not start.
The definition of insanity.
Eric's solid acumen aside, this is a pain in the ass and a unnecessary expense for the poor house wife who needs to take her gaggle of children to soccer games.
Yeah, life became very complicated and distracting with micro processors: and all by design.
We are living in the last days days, we should be frying bigger fish
I like technology when it works but I like my old pre computer truck even better, great video 👍😁
Wonderful to watch a master sleuth at work. 🕵️♂️
Some crusty's, way at the back of the car, and the engine won't start.
Stupid can bus.
Nice find Eric. Tracked down the beast
Good find..! That module looks just like a corroded fuel pump driver module.! Thanks again..! Very informative video..!
Great video. I am watching you from Kalisz Poland instead of Kentucky.
Great video, and congrats on 888k subscribers.
didn't have that problem with my 1976 Buick Electra 225 😂🤣😅
Growing up my friend’s dad had an 80 I think . We called it the Sweet Daddy Big Ride, it was a smooth machine.
@@scottzehrung4829 and the gas milage wasn't bad either
That's absolutely brilliant
