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.
@@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
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
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
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!
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.
Eric, I have an 05 Chevy Suburban in which the “service 4wd” comes on every once in a while. I watched a couple of RUclips 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.
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.
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.😎
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.
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.
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!
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.
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.
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 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. 😁
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.
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.
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 cannot even imagine having an expander as a "mature" adult. My son had one as a child to make room for all his teeth. Every week I got to put 1 turn on the gear and my heart broke to see him in such pain. Thank you for still making a video for us and a 2 parter non the less!
Retired dentist here. For children the joint between the two halves of the palate are quite easy to separate with the expander. The child is still growing so as they say the joint has not fused or grown together. In an adult the joint has fused. So separation is very difficult and if expansion is done too quickly it can be quite uncomfortable. There is a procedure where the joint is opened surgically to make the orthodontic procedure a bit easier. 😮
@@williambranham6249 Yep; my parents were too tight to pay for orthodontics to fix my crowded teeth and when I went to an ortho as a mature age adult, he told me my palate needed to be surgically divided.. painful, expensive and inconvenient; he suggested I'd spent the best part of my adult life with my teeth, so just leave them be was his advice.
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.
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.
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?
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. 👍
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.
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 RUclipsrs 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.
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.
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!
You're one of the best mechanics i've ever seen. I wish you were my mechanic. You have a great family and seem to be living the dream! Always remember, somebody is always watching you; You're somebody's role model. Keep up the great work! Bravo!!
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)!
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
All I could hear in my head was Rod Serling: “You unlock this door with key of imagination. Beyond it is another dimension - a dimension of sound, a dimension of sight, a dimension of mind. You’re moving into a land of both shadow and substance, of things and ideas. You just crossed over into the TWILIGHT ZONE!”
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)
My dad had a 04 Colorado z71 4x4 with the 3.5. His truck had the same problem. I removed the same connector to check for corrosion. I found nothing wrong plugged it back in and it fixed itself. He owned the truck another 5 years problem never came back. Sometimes that's just how things go.
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
When I had my 02 Ford Ranger. I would put the truck in neutral and go from 2 wheel to 4 low stopping at each of the settings. You have to exercise the system to keep it working.
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.
when you were reading off the diagnosis sheet it stated that only 2wd was available if a dtc was set. When you cleared the dtc syre enough it all worked. Maybe a 1 second blip on the atc?
2 oz. ice cold brandy every 10 minutes until swelling goes down worked for me. Popsicles work also. You moved around a lot of wires before the popped fuse. That one could come back to haunt you .
Eric, thanks for all the videos of diagnostic and repairs you do. They are truly educational. Also, 🎄HAPPY HOLIDAYS🎅 to you and the family, as well as the SMA community👍👍👍👍👍😸🤗🐺
In my job of 31 years, we saw fuses just get tired and wilt when they got old. No black residue to indicate any kind of overload blew them. Following the wire to look for chafing or other abnormalities was a wild goose chase, so we replaced the fuse and it lasted for many years after. Yeah, random fuse blows are weird but true, and very annoying.
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

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

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)!
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!
This is the real world of mechanicing.
Never a dumb video The content is exceptional.
Your classic reach around is my favorite method and should be a requirement for every video.
Get well soon bud. Always wonderful to see you. Cheers
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
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.
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
i like it when it test your noddle mr.O the harder the better nice job man
Electrical gremlins can make you crazy. Eric you have excellent diag skills. If anyone can figure it out, it's you.
All I could hear in my head was Rod Serling: “You unlock this door with key of imagination. Beyond it is another dimension - a dimension of sound, a dimension of sight, a dimension of mind. You’re moving into a land of both shadow and substance, of things and ideas. You just crossed over into the TWILIGHT ZONE!”
Okay, when it wouldn't start I would have pushed it out into the street. Apparently I shouldn't be a mechanic. Great job as always.
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)
The joys of modern electronics on modern cars
My dad had a 04 Colorado z71 4x4 with the 3.5. His truck had the same problem. I removed the same connector to check for corrosion. I found nothing wrong plugged it back in and it fixed itself. He owned the truck another 5 years problem never came back. Sometimes that's just how things go.
Good luck for your recovery Eric and a good video
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
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
When I had my 02 Ford Ranger. I would put the truck in neutral and go from 2 wheel to 4 low stopping at each of the settings. You have to exercise the system to keep it working.
Liking it, well deserved!
You've never made a stupid video. Thanks for another good one; looking forward to the next!
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.
This video was quite entertaining. It was also educational, but mostly entertaining. Probably not what you want to hear Eric, but that's all I have.
I have been there many times over the last 50 years.
when you were reading off the diagnosis sheet it stated that only 2wd was available if a dtc was set. When you cleared the dtc syre enough it all worked. Maybe a 1 second blip on the atc?
Oh, man, you ever get the feeling that you'll be seeing that "be back" again?
I think you missed that this is NOT a self clearing code! See video at 6:50: A scan tool must be used to clear a DTC
2 oz. ice cold brandy every 10 minutes until swelling goes down worked for me. Popsicles work also.
You moved around a lot of wires before the popped fuse. That one could come back to haunt you .

I quit too. That’s it!
Your the go to guy for honesty
Don’t quit!!
All I’ll have is Scottie
Lol
Eric, thanks for all the videos of diagnostic and repairs you do. They are truly educational. Also,
🎄HAPPY HOLIDAYS🎅 to you and the family, as well as the SMA community👍👍👍👍👍😸🤗🐺
Thanks
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.
We fixed it so it won't run. CLASSIC!
It's that MAGIC TOUCH Eric!
In my job of 31 years, we saw fuses just get tired and wilt when they got old. No black residue to indicate any kind of overload blew them. Following the wire to look for chafing or other abnormalities was a wild goose chase, so we replaced the fuse and it lasted for many years after. Yeah, random fuse blows are weird but true, and very annoying.
The diagnostic videos are the best and my favorites!!!!!
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 😄
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
As honest as you are, the customer got his monies worth.
Rather watch a "crappy" SMA video than a lot of other channels' best efforts!
Loved you in "The Music Man," Winthrop.
Wow… over 750k Subscribers! Not hard to see why. Well done SMA
I sense your aggravation ! Glad to see it happens to others !
