"Two In A Row!? I Really Am Quitting!!" Ok Scotty! See you tomorrow!
Lmfao, underrated comment
🤣
I had to block Scotty's channel from my search results. The clickbait is too much. Eric, Wizard and Ivan are the real YT mechanics.
@@matt9c1 how do you block a channel?
@@matt9c1 Don't forget about Rainman Ray!
"I hate to go down the flow chart for broken dreams," luv it lol 😆
Who just watched Ivan, pine hallow auto diagnostics on Saab using tech2.
Service Bulletin No.: PIP5098,
Date: March, 2013
Subject: Service 4WD Message And DTC C0327
Models: 2004-2012 Chevrolet Colorado
2004-2012 GMC Canyon Equipped with 4WD
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may comment on a "Service 4 Wheel Drive" message displayed in the DIC. Technicians may find
DTC C0327 stored current or history in the TCCM. Concern may be intermittent but customer may comment that happens mostly on initial drive cycle or several hours of sitting in cold or damp conditions. Concern may also be
intermittent when attempting to shift into or out of 4WD.
Recommendation/Instructions:
Perform diagnostics outlined in service Information and if no root cause determined then inspect circuit 550 ground
circuit for the transfer case encoder motor channel circuits. One suspect location is connector 2 terminal F7 in the
under hood bussed electrical center. Check for proper terminal tension, corrosion, etc. Replace terminal if any
concerns are found with the terminal. Usually this condition is easiest to duplicate under high electrical load
conditions like starting the engine and shifting the transfer case.
I found out that the 4wd sensor on the t case has bad wiring that will erode to the elements. Replaced the sensor and everything is fine now
I prefer to get fired before quitting. 🤣🤣🤣🤣
you can't fire me cuz I QUIT!
Quitting feels good, getting fired, not so much.
Too funny
@John Valle I got fired , but I couldn't physically work anymore. But it still feels horrible 😞
Failure is not an option........I heard that from somewhere. Might have been on a different channel....ray something or another
Getting a little Kilmer with headlines. I love it!
NOTHING stops Eric O. from talking and imparting his knowledge on us.😎👍🇨🇦
I may be talking funny, but you’re gonna learn Dag Nabbit!
@@TheEdwardSaenz I did laugh pretty hard when I saw this, but I can't help but remember... he's not all that old lol.
I imagine someone saying dag nabbit as someone who's like 80 or 90 yrs old screaming at children to get off his lawn. Lol
@@Ibonic or how about Dad gum yuh durned dude!!
Been reading the comments and someone mentioned contact cleaner. Normally the sort of corrosion you get on contacts has to be really bad on high current circuits you used to find on cars and usually resulted in terminally burnt contacts, but on modern cars with low current sensor circuits even mild corrosion can cause problems and contact cleaner might be a help. Sometimes just undoing and replugging a low current contact can be enough to make it work for a while, but contact cleaner and lubricants can correct it for much longer. I repair old electronics and computers for a hobby so this is knowledge born from experience!
I actually just quit my job as a mechanic after 22 years. I’m cool. Sold my building and everything.
I stopped in March after 20 years and best decision I have made. Good luck to you!
@@FABAutomotiveDetailing Thank you.
Good luck 🍀
@@meatballmagoo6134 On my building maybe. Guess that’s what you define as “rich”
What the heck? What are ya'll gonna do now?
Eric, I have an 05 Chevy Suburban in which the “service 4wd” comes on every once in a while. I watched a couple of CZcams videos on this error and learned that similar GMs all lead to that ground on the frame due to corrosion. For my model, I crawl underneath the body under the driver’s seat area and sand the ring terminals and frame then bolt it back together. Basically what you did but I sand the frame where they mount. Fixed again for a long while.
Had exactly same issue on a similar age Colorado, mine had an intermittently bad ground on the encoder motor caused by bad pin fitment in the connector to the encoder motor.
My daughters home for the holidays, noticed I’m watching SMA on the tv. She states I have weird taste, within 30 seconds she says I have no idea what he’s talking about but it’s like watching an uncle talk cars
Eric, you've just become so good at what you do. All you have to do is be near a vehicle, and it fixes itself. Great video, as always!!!
When we first started getting cars with obd2 requirements I had a friend borrow my only scanner to check on a code on his car, he brought my scan tool back the next day and told me that he connected the scan tool to the car and the light went out and it never came back with a code but it did light on every startup so he said the scan tool scared the code out of it
Yes, his mere presence scares the vehicles into behaving better! ;-) They know they cannot win!
We said this was going to happen.

no no " thuffering thuckotash sthylvesther "
Boy oh boy. Do I relate to this! This kind of video is comforting to all DIYers who have “problems just disappear”. Eric, you get a lot of points in heaven for not losing your cool when that fuse slipped out of your hand. If that was me …. after all that work …they could hear me screaming in the International Space Station.
Me too.
Your videos are many things, Mr. O, but they are never "stupid." We *always* learn something.
Scotty would be so proud of the video titles 😂. Keep em coming!
All of scottys titles are in doom mode.
Scotty had admitted that he uses over the top clickbait titles to draw more interest. Personally it’s a turnoff and I ignore a lot of his stuff now.
If y’all watch Doug (Soundman Enterprise) his son looks like Scotty a bit. Funny. Doug uses him as a Scotty look alike punchline joke.
@@afellowinnewengland6142 I don't even watch him anymore because of this.
@@afellowinnewengland6142 me too
Hey Eric, your reading/expander situation could be worse...you could be reading service info about a six-cylinder Suzuki 😊. Thanks for the videos even amid the frustration!
Excellent job trying to diagnose this. None of your videos are stupid. This is real world stuff. This kind of thing is probably more common than not. The way those grounds looked it could very well have been an intermittent circuit problem and once it sets the code nothing will work.
This video really helped me out. I had the Service 4wd System code on my dash and lost the lights at the push button 4wd. I accidentally had unhooked the 4wd connector with the battery connected. My inexpensive Dongle OBD reader couldn't get the code neither could the local autostore. Upgraded to a OBDLinkMX+ and was able to erase the code. Truck shifted into 4wd with no issues afterward.
Definitely not a stupid video. I always enjoy watching your videos. Very informative. Thank you.
Something to keep in the back of your head with mechanical electrical contacts: things that aren't gold-plated need a couple milliamps or so going through them too keep them happy. So for something like this position switch, expect ~2--20mA current. 100mA would be a lot for this. In the industrial world, this is enough to light a low efficiency LED optocoupler, which is for us the typical case. I've seen bad designs that use much less than 1mA, but they all seem to date back into the 90's or 80's before electronic engineers got smarter.
Oh, man, you ever get the feeling that you'll be seeing that "be back" again?
Watching these videos really makes me happy my old Jeep Cherokee and my 99 Ram both have the good old lever on the floor!🎉
Ran into this 4 wheel problem several years ago ran through every test and actuated everything and started messing with wiring at 4 wheel module and found a connection issue I don't remember exactly, it was a bad terminal or bad wire connection at terminal. Love your videos and good luck with Colorado.
Hope you start feeling better. Thanks for still do this video
Mechanics of yesterday are today's electronic technicians; it's amazing the body of knowledge these people now have. And, Eric excels in this capacity.😎
No quitting for you sir … you’re one of the last sane people left in this world and I rely on you to keep me sane !!!
Eric has literally evolved into the next level of mechanic that just the makes cars fix themselves..
Man I appreciate the time you spend teaching you can’t find stuff like this out there damn the ghost he will be back eventually
Thanks for taking the time to do such a great job with these videos. I have learned a lot.👍
I have fixed nearly as many things by accident as I have on purpose. This video comforts me in that my experiences are not that abnormal.
Best diag videos and advice on the web..seamless with the screen shots of computer..easy to watch and I always learn something from watching you.
I particularly love these types of videos. It shows real life. As a DIY, when stuff like this happens to me, I feel like I'm missing something, probably something stupid. Or it's just me. Comforting to know that it isn't always me. 😁
Nice to see Eric is taking care of himself!
Get well soon bud. Always wonderful to see you. Cheers
glad to hear there's a part 2, i got a 05 coly hanging on with 175k that can use all the repair data i can find, thanks for posting, don't ever give up!
Thank you Eric for the video it just goes to show for us shade tree mechanics and people who don't know about their cars this new stuff there's no way we could figure out how to do anything like this appreciate your knowledge and appreciate your tenacity between the Dodge and this one it's been a humdinger thank you for your hard work though
Blowing the fuse is interesting. I've run into similar in general electronics. Chassis ground in some electronics is not the same always as circuit ground. Sometimes if you put a circuit ground onto a chassis ground or verse/visa weird stuff happens and things blow. It would be interesting to measure voltage and resistance between your 2 grounding points. Should be zero volts, zero ohms.
That particular GPS unit which is an aftermarket accessory is designed to blow the starter fuse. It's designed that way so if somebody attempted to rip the module out so that vehicle cannot be found, i.e. stolen, then the vehicle cannot be started.
The fuse was blown purposely to prevent the vehicle from being started when he picked up that module and caused the inertia circuit to send powered to disable the fuse.
Just a FYI.
That's a DEI python GPS.
Hi,that's why I wound up putting a peice of 1 inch broom handle in my front actuator for the snow season.The tyranny module can't be reached without being on a lift and jamming my hands up over the tyranny hump to try to access it.,hahaha.2000 6.5 4x4 1 ton.
I don't care if you fix them all or not. I just enjoy watching. Thanks Eric.
Some people don't use the 4x4 all summer and then they wont work in winter... LOL Thanks for the great troubleshoot as always ! dang GM's haha.
I loved when you said "well we fixed it till it was broke" . Doing the right thing ain't always easy, is it!
Clarity in this one on avoiding wild goose chases and sticking to the data is great advice.
Thanks for another good one!
i like it when it test your noddle mr.O the harder the better nice job man
In addition to being an excellent mechanic, you are a
very good technician!
Few garage owners know how to combine the two...
Congratulations for this excellent work Eric, very instructive. 👍
Them 4×4 systems just wanna be in a nice warm shop to work....just like the rest of us🤣👍
Eric O. Laying on of hands….healed…it works…job done.
Eric "Midas" O, Hail to the King! It's a blessing and a curse buddy. 😁
Sometimes you just got to walk away and come back later good to see that we are not the only one that gets pissed off 😄
It’s fixed til it breaks lol. I love it. Greatest channel on the CZcams
Thank you for the video how the full drive fixed itself is very interesting and then why it wouldn't start is crazy unreal love the information thank you
I've seen some wonky stuff when it comes to trucks and 4WD operation. A lot of issues can simply be fixed by resetting the system of its codes and letting it begin a new. Granted Eric you are very thorough and did the correct tests in order to cover yourself.
I feel real I know what pain is all about I just had seven crowns put in my mouth and boy did they hurt just take it easy and you will make it through you're a very good mechanic I like watching you I learned things from you keep up the good work thank you for all you do for us CZcamsrs have a wonderful day and Merry Christmas and have a happy New Year
2 crowns here, but man got almost fully got up in the, just pull your teeth and save up for implant scam. Had to go to a different dentist who was noo, that is always the last option, and my teeth were very saveable.
Love how u show us every thing ty I find this vary informative have a merry Christmas
Orthodonture is a pain. I have felt your pain. I know you will keep on keeping on. Happy Holidays to you, Mrs.O and the whole family.
Thank you for another great video! Although I use Deoxit some of the time, I use CorrosionX more often. Spray the plugs while they're apart, take connectors off, clean them, spray them, re-connect and spray them again. CorrosionX stays on - like FluidFilm or Surface Shield.
Eric, from my experience with these, the encoders get oxidized contacts and work intermittently. The code gets set, after reset it will work for a while then fail again. You may want to throw this part at it.
The diagnostic videos are the best and my favorites!!!!!
I really love this channel. Eric and Mrs. O are amazing together.
As a fellow tech in his 40s with bad teeth, I applaud you. I don't have the balls to get mine fixed
I didn't for a long time. Ya got to do it man trust me.
I am 49, I see the cost I say just yank em. I still play ice hockey so that enters in to it too.
Good luck for your recovery Eric and a good video
I have been there many times over the last 50 years.
Your the go to guy for honesty
Don’t quit!!
All I’ll have is Scottie
Lol
I disagree with you that this is a stupid video. It is valuable to me to see how you approached this issue even though it seemed to fix itself.
Thanks. You are one heck of a mechanic and teacher.
Nothing like self repairing automobiles LOL Great diag as per usual Eric O.
Yeah Boy , another part 2 or 3 or 4 this should get us to Christmas Eve ,don't disappoint Mr O
Never a dumb video The content is exceptional.
This circuit "fixing" itself actually makes sense: as Eric explained these circuits use very tiny signals. He proved that by probing them with a 100mA lamp that failed to light up.
So even the slightest bit of resistance in a connector will be able to disrupt the signals. Sometimes it's enough to simply unplug the connector and plug it in again to clean up the contacts enough to lower the resistance enough for the module to start functioning again. At other times the module might have gone into a kind of "don't know what's happening" state, where it simply can't "choose" which mode to be in. Back probing the signal wires alters each input's state in turn with a high-resistance load that may just be enough for the module to start detecting the inputs again and select a mode. Problem solved, although a thorough cleaning of the connectors with a special contact cleaner is advisable to prevent future problems.
You make the best teacher. Great job!
Thanks again for another awesome video!!( keep up the great work, and videos)😁👍
NOT a stupid video. This is the real life of an auto tech, right down to dropping a fuse into the abyss.
I had one of these as a work truck, when the temps would drop the 4WD actuator would freeze up and throw codes, once things warmed up it worked fine, fun to track, useless in the winter when you needed it :D
I was thinking the same but I'm sure Eric knows more than me. Is the transfer case fluid sludge and stiff enough in cold weather to error out the servo?
A Mrs. O cameo, nice. Clip clop, clip clop, my beating heart. Amish humor. You don't hear those words uttered everyday. Pretty funny joke. Things go better when you can make each other laugh.
The screen capture PIP does make it *a lot* easier to see what you're hacking away on that computer, I'm glad you started doing that. The vehicle knew you were around and fixed itself! Computers do that to me.
Your classic reach around is my favorite method and should be a requirement for every video.
You've never made a stupid video. Thanks for another good one; looking forward to the next!
Loved you in "The Music Man," Winthrop.
Sorry Eric, but it was kinda funny to see you diagnose, then fix it with the magical touch and angry eyes. Keep up the great work!
Vehicles like this one are so much fun. I remember getting ones like these and thinking, hmmm, where do I start? Pick an area and just go with it pretty much. I wonder if this is one of those GM's that has green corrosion growing on the bottom of the fuse block.
The joys of modern electronics on modern cars
Thanks Eric for you videos love your commentary (watch out for internet comment generator's lol) it's great to see your family included in your channel. Merry Christmas
LOL @ Eric and "S" You are doing fine! Carry on ! 👍
I feel your pain. I remember my old braces days. Turns out it was a waste of time, pain and money as my teeth are as terrible as they ever were. Wish you the best on yours!
"I Really Am Quitting!! "...yea you and Scotty Kilmer !
You got that magic touch!
Real life, wild ass shop stuff right there folks!!
Thanks for muscling through the mouth issue and making a video for us.
I Subbed a while ago and your content created has really improved.
Can't wait for part two. I can't tell you how often this happens in computer repair...no clue, it works call me when it doesn't
Eric O...the 4 wheel drive system whisperer. 😄
Good thing Mitchell didn't write, Sally sells sea shells down by the sea shore multiple times. Three of my kids went through the same thing.
Reminds me to try my 4 wheel buttons out, wintertime is coming.
I would be interested to see a scope trace on those encoder wires as the T case is being shifted through the different modes. Might show you if one of the encoder switches has a broken spring or something, randomly connects from time to time. Wiggling the wires while watching the scope too. If a wire is dodgy, you might see the noise when moving the problem area around. No replacement for seeing the live data with your own eyeballs.
I had a vehicle that would very occasionally give an airbag light. Drove me nuts. Started pulling up live data graph whenever i'd drive somewhere, and found that the resistance of one of the driver's side airbag squibs was noisy and erratic once in awhile. Supposed to be a couple ohms, would occasionally spike to like 30 ohms. Pulled the airbag out, and the guys who rebuilt the vehicle from a previous crash had replaced the snap connectors for the airbag with used ones... and had just twisted the wires together and taped them, no solder no crimps. That was pointing at my face while I was driving (probably not going to go off uncommanded, but you don't mess around with shoddy wiring on SRS systems)!
Job Security Eric! you LOVE it !!! LOL
It's that MAGIC TOUCH Eric!
I owned a 2012 3.7L 4X 4 GMC Canyon for 5 years and 70k miles. Every once in a while when the road was wet or snowy the Svc 4wd would come on. And when conditions dried in a couple of days, the light would go away. I checked and cleaned connectors at the transfer case with no rhythm or reason to why would come on. But there was one time when one of my brake light didn’t work and I cleaned out a body connector towards the rear of the truck and I swear that kept the Svc 4wd light away for like a 1 1/2 years! That was my experience for what it’s worth.
I wish i had half of your knowledge and patience, I can’t wait for the day that I don’t have to fix anymore vehicles 😅and helping my company get richer
ya just have to love it when by checking connections and stuff, the vehicle becomes fixed. Charge your time and don't lose sleep about it. If it comes back, you'll adjust the $. Merry Christmas to you, your family and staff (because they aren't any help LOL)
Eric O is just like the Energizer Bunny without the drum
Yes Eric I know all about being pissed off with even my smart phone so good luck with that . Anyway merry Christmas to y'all from Ireland
Quality content as always. What would be nice sometime for a layman like me… a brief explanation as to why or how you pick the scan tool for each application. I’ve seen in past videos that the autel sometimes isn’t completely compatible… but it almost seems like you use a different scan tool for almost every video 😅… just wondering why and or how you decide which one to use/start with
All depends on the manufacturer. For example, the last video he used witech bcuz he had access to it and it’s Chryslers scan tool software. So it has the best and most info and work support to use. Bottom line is, he has the manufacturers software and or tools available, most of the time that’s the way to go. Rather than using an aftermarket all around scan tool. Like autel
@@christiangraham4579 and this video he used gm tech 2 which is the OEM scanner
