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.

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!

[@weshawkins7165]

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.

[@paulmoir4452]

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.

[@PK15306]

[@williambranham6249]

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. 😮

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.

[@wiley0714]

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.

[@tjroelsma]

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.

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.

[@christiangraham4579]

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

The reason it didn’t work until you cleared the codes was because it requires a scan tool to clear them. If you go back and look at the clearing conditions, it states that.

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)!

[@windward2818]

The code sequence 2H-N-4H-4L, as per your sheet, has three encoder signals changing state and one not changing state. However, I think there must be intermediate states, not listed on your paper print out to give the motor better positional resolution. My guess would be P is used for end positions, and ABC used for intermediate absolute position represented as a Gray Code sequence. When in doubt for an intermittent which will not repeat is clean connector contacts. Spray the contacts with Deoxit D5, cycle (connect/disconnect/connect) the connector a few times and this will, in my experience, rule out a faulty pin connection. Then as you have done inspect potential problem areas like chassis grounds.

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!

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.
