Wow 5 times for the same repair sounds like you got a case for a lemon law if you have all your paper work showing each time it went in and it being the same problems you might want to file for a lemon law but also check with you state what the requirements are I've heard it is different in each state but here in Cali 5 time for the same problem and it is still not fixed it counts for a lemon law and you can tell them to give you a new truck

 

I assume you're getting a code that you can read as well?

Would be interested in seeing what the dealer wrote up as far as codes read, troubleshooting performed, and further suggestions.

 

No, not "common" first I have heard of this...

 

New to me also. Either the problem is intermittent and hard to track down or you have incompitent techs working on your truck. I would bet that if it was a common problem they would know the fix.

Trucks of this era were known for poor electrical connectors/connections. Hope they fix it while under warranty. I have suggestions, but they are on a very high level of diagnosis (depending on codes and more info).

I just moved from Glendale to Baltimore, and I know a few good diagnostic techs. If the problem is consistent, I will gladly refer you to them if you have some patience. The ones I know are better than me with diag. PM me with details if interested.

 

Thanks for your responses. The code that always shows up is C0710. It is covered under warranty. I have enough history on this subject they said it would continue to be covered. I am almost at 36000 miles.

 

Refer to TSB - PI0639A as I am sure they have also. That is probably the common problem. It deals with corrosion in the steering wheel angle sensor connector. The 'fix' is to clean the connector and put dielectric grease inside before reconnecting it.

#PI0639A: Service StabiliTrak Message Displayed in
DIC, StabiliTrak Indicator Light On, DTC C0455 and/or
C0710 Set - (Mar 23, 2012)
This PI is being revised to update the Recommendation/Instructions information and the
Parts Information. Please discard PI0639.
Condition/Concern
In rare cases, some customers may comment about the Service Stabilitrak message being
displayed in the DIC. The StabiliTrak® Indicator light may also be on.
When checking the vehicle for DTCs, the electronic brake control module (EBCM) may report C0455
and/or C0710 set as current or in history.
This condition may be caused by an increase in resistance in the circuits connecting the steering
position sensor and the EBCM due to fretting corrosion on the connector terminals.
Also, the male to female plastic connector may have excessive clearance that can cause the
connector to move up and down.
Note: Fretting corrosion looks like little dark smudges on the electrical terminals and appear where
the actual electrical contact is being made. In less severe cases it may be unable to be seen or
identified without the use of a magnifying glass.
Recommendation/Instructions
Important: DO NOT replace the steering position sensor for this condition. The terminal pins on
the sensor do not have the same concentration of deposits.

You are not authorized to view the requested information. 4/2/2012If the condition cannot be duplicated, the repair is complete.
If the DTC resets, replace the steering angle sensor harness side connector with the service pigtail.
Refer to the Steering Angle (Position) Sensor connector end view in SI for the correct service
connector part number.
2. Add a piece of Adhesive Back Shim Stock the width of the connector to the flat surface on
the male connector. This provides support to the connector to keep it from moving up and
down.
Important: DO NOT apply an excessive amount of dielectric lubricant to the connector,
as hydrolock may result when attempting to mate the connector. Use ONLY a clean
nylon brush that is dedicated to the repair of this specific condition.
3. With a one-inch nylon bristle brush, apply dielectric lubricant to both the sensor side and
the harness side of the affected connector.
4. Reconnect the steering wheel position sensor connector and wipe away any excess
lubricant that may be present.
5. Attempt to duplicate the condition by using the following information:
- DTC Diagnostic Procedure
- Circuit/System Description
- Conditions for Running the DTC
- Conditions for Setting the DTC

Thanks Extremity for your post. Very informative.

 

Great find! OP-Keep us posted on the outcome. This is the second Service Bulletin I've seen regarding corrosion in connectors and it may be a clue to many of the ABS and Passlock problems that are next to impossible to solve. Maybe the Dealer's Service Department isn't aware of this Bulletin.

 

Here is the latest update::

Talk with GM they basically told me if I didn't give the dealer one more time at fixing the issue they would not consider any other possible solutions.
Took it in to dealer they talked with engineers at GM and here was the only solution they could possibly come up with. Make a new wiring harness that connects to the SWPS and use a heavier gauge wire to make it. They are sending the dealer the necessary parts to do this. Sounds like a last ditch effort to me. GM did say if this didn't work then they might consider a repurchase of the vehicle. We shall see what happens.....

 

As always, keep us posted. Would hate to lose a truck you know and love for a silly electrical 'gremlin' as they call it around here.

 

Got truck back this afternoon lets hope this fixed the problem. They had truck for 9 days.

Here is what they did.

Contacted Tech Center and was instructed to re-wire steering wheel position sensor wiring from sensor to ebcm.
Completed re-wire terminal to terminal circuits 1056,1835,1763,1764,1765 and 1059. New service connecter used at steering positions sensor to secure connector body for correct fitment and solid connection. Connector X276 bypassed as directed by TAC. No faults found during extended testing. 100 miles testing done as directed by TAC with no event.

 

So in other words they replaced the connector to the Steering Angle Sensor. From that harness/pigtail they ran it straight to the EBCM. Doing so involved splicing past another connector it ran through.

I am glad they are trying to fix it. I would not like having my truck spliced and hacked into, but if it works, then I would be moderately happy. It almost sounds like you are a test case for others. If so, then glad to know you may help several others. Also, nine days of testing sounds like the above is true and they care.

Good luck, keep us updated. Chances are your post will appear on many google searches in the future for this odd but common problem.

 

Thanks for returning to let everyone know the results. Hopefully they have corrected the problem. It is still a bit of a mystery as it appears that they were never able to determine the exact cause of the issue. Your truck configuration is certainly not unusual and this is the first time a problem with the system has needed a complete rewire to fix.

 

Had truck back for a little over two weeks now. 1300 miles on it. Went on 10 day deer hunting trip in the mountains no problem. Went to work and when I turned into the driveway and went to park looked down and what did I see SERVICE STAB SYS.... I'm at a loss here. Contacted GM again and they have handed my case off to another person. This makes 5 different people since this mess started. Will keep you guys informed.

 

Sorry to hear that the problem resurfaced. Doesn't say much for the capabilities of the GM Technicians, does it. Apparently the problem hasn't been elevated to the level it needs to be to find someone knowledgeable enough with the details of the system. Good luck.

 

send a message to our GM "liaison" Jennifer, I think for now anyways,

LOL. I was thinking of suggesting that. It will be interesting to see how productive that turns out to be.

 

Yeah I figured it might be a good opportunity to see the level of involvement they intend to offer,

 

silly question, but where is the steering wheel sensor?
