"Not a network guy" then proceeds to give one of the best explanations of the network system ever.🤷

The dude who is always mowing the grass, definitely watches these videos... guaranteed.

22:30 Eric's Neighbor with the nicest lawn: "Hey, the powers out. What to do? Oh, yeah...cut the lawn!"

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!

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.

You were cutting the network down and lawnmower man was cutting what's left of the grass. 😂

"I don't speak creeper so...." That one gave me a chuckle. XD

Eric, you don't even need electricity to diagnose a car. You are the man!

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.

The singing getting the creeper I just started laughing. Perfect song and timing like always.

Nothing wrong with people sending you money and they get to see a video a day before. They chose to send you money, I support by watching!

And remember folks, just because Eric can do it, doesn't mean any of y'all can do it.

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.

Power outage but the show must go on !

Eric you say you are not a network guy but you troubleshoot the network better than some people I work with and I am an IT network guy!

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. 😊😊

Ivan will be proud that you used jack stands and a creeper.

Eric rocking the jack stands and creeper like the rest of us peasants. 🤣

"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!

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

Four wheel peel or two tire fire 😂 I love the terms you have for certain things lol

Crawling around a car old school sure makes you feel old the next day when you're up there in years 😢

I had serious deja vu when Eric was under the car, on his back with the car on jack-stands... (been there, done that)!

Almost gave you a 1/10 for this one Eric than the LAWNMOWER MAN SHOWED UP! 10/10 BROTHER!

You are amazing Eric, been watching for about 4 yrs, your humour, banter and knowledge is the best, told my wife about Bob, had her in laughing.

Not only do I learn from your videos, I always get a laugh or two. Love the humor.

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.

This video is a good example of what happens when you combine shoddy workmanship with too much electronics in a vehicle.

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.

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)

Thank you Eric. Some folks are well, just idiots. I love the process you use to figure out problems.

I'm always impressed the way you get around your diagnostic tool skills! 👍👍

...Actually, we know you got the job, 'cos we see the link for Part 2 there. 😁

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.

Dr O working on another fine GM product bravo sir

Love to watch you work, great video Eric.

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....

Thank you for all your effort and your great sense of humor . Brightens up my day, You can do no wrong.

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.

Fantastic video showing us how to break down the system! Thank you

Thanks for the video Eric.

"She's real fine, my 409. Giddy up, giddy up 409"

Excellent diagnosis and presentation as always

Amazed at your process for deduction

Always loved the great analysis theory and presentation to take you right to the problem

One very good lesson on can bus systems. Thank you.

“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”.

I am blown away. I have the same Autel and struggle with it. You make it soo easy. Your the greatest. 😂

Even in the dark, Eric is still in the light! Great job!

Fantastic problem solving here, thank you for the video 👍

Dude. You are such a skilled mechanic and entertaining/witty. Rare combo

another great diagnostic video!

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.

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.

That's absolutely brilliant

Good find..! That module looks just like a corroded fuel pump driver module.! Thanks again..! Very informative video..!

My man You been there for long time.. "say less pay less" that's awesome Eric 👍

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!

Yes! Multiple Eric O videos, it's a good day!

Good job Eric!

The power was out, but at least that guy stopped mowing his lawn😂

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.

can you believe this fella, has a lift and uses the creeper. 🤣🤣🤣🤣🤣 couldn't resist poking fun.

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.

Great network diagnosis.

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.

@21:35 "Oh, you're about to get some flyin' lessons"........ 🤣🤣🤣 I'ma remember and use that one!!

Best kind of SMA vid

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.

I like technology when it works but I like my old pre computer truck even better, great video 👍😁

Great video, thanks for sharing 👍

Come on there Eric O. The real DIY'er uses a piece of cardboard not a creeper. 😂

Eric going the extra mile with the creeper footage with some simon and carfunkel as a bonus!

General Motors has a service bulletin on that connector for any suv with AWD for corrosion. When you showed the dash I immediately knew what it was.

Boogety boogety boogety, let's go racing boys. Good old DW!

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, 😉👍🏾

Wonderful to watch a master sleuth at work. 🕵️‍♂️

The turbo noises…love it.

All mechanic videos are interesting

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~

Great video, and congrats on 888k subscribers.

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

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.

That turbo soundfx is top notch :)

5:18 🤣 I love how he mentions memes. Shows he's in tune with things. Such a funny guy.

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 .🤣

Eric I love the way you think. ❤

So damn impressive!

I hope the customer listens to you. ❤❤

"Oh, you are about to get some flying lessons" 😂

Tells it like it is Hell Ya Brother keep up the excellent work

Here's a tip: if you fasten the seatbelt, the annoying dinging sound will stop. I learned that while working on a Ford after my ears started to bleed 😅

"Hey boss, our dealers are complaining cuz they're not getting enough service work" Well, how about if we put a real complicated electrical connector under the car where it will be sprayed with salt water and mud? " Good idea boss, annnnd we can make the insulation on the wires protein based so rodents will like to eat it! Great Idea! That oughta do it!

Good diagnostics brother.

Great video. I am watching you from Kalisz Poland instead of Kentucky.

X112... That takes me back to West Germany, late 80's, Army days. lol. Super stuff it was!
