Dealer just cannot fix problem, what next ???
I have an '04 vette that has been in to the dealer for service about 6 or 7 times for chronic - traction control / active handling / abs - errors. They've replaced some wiring, replaced one computer and some other stuff, all to no avail. The code always points to the RF wheel sensor.
This is consuming much of my free time dealing with this. In this latest round I picked the car up last Tuesday, drove it to Dallas from Austin and on the way home the lights came on again - same errors.
The extended warranty went out 3 repair attempts back. I'm stuck in an endless loop here. I was about to call the dealer yet again and see what they want to do about it (if anything) but I figured I should ask here as well and see if someone has ever had similar issues and how it was resolved.
Is there any other recourse I can get from GM? What do you do about a problem that the dealer just cannot fix?
Thanks

The EBCM is the computer system that is in control of the system you are referring to. There is a braking system unite attached to it. There are wheel sensors tied in from all 4 wheels. Lots of places for shorts or malfunctions. There is even a ground junction close by on the frame where several ground wires meet close to the EBCM,,and there have been cases where the connection or the mounting point had corrosion and caused problems. You need a shop that specializes(or at least has a good % of corvette business) to trace all the lines for shorts,,track all the grounds and narrow it down to the computer,system pump or whatever!! It is VERY common for dealerships to NOT have a corvette savvy mechanic!! If it is going to be a warranty situation,,you will need to find a dealer that sells/services a number of Corvettes!! Hope this helps!!
,,,,,,Jus t noticed you are in Texas. Don't know exactly where you are,,but Corvettes of Huston and Corvettes of Dallas(business partners) are 2 WELL known vette places !!

Haven't experienced this issue myself but, I would recommend giving Todd or Jeff a call at Corvettes of Dallas. I take my car there regularly for service and am always satisfied. Great bunch out there. Definitely would not hurt to call them at least. Good luck.

I recommend that you read the following post by Bill Curlee regarding chassis grounding points. Poor ground connections can cause false codes.

Just curious,do you have LED tail lights? If you do,the quality may not be good and you may have issues with that light coming on. As someone else said,it is tied into the braking system inlcuding the lights.

Took it back in to the dealer. They are willing to take another look at it next week. If that doesn't get it fixed I might take Todd up on his offer at Corvettes of Dallas.
Pump03: The service manager said today he had already been thru all the grounding points... although that doesn't necessarily eliminate grounding as the issue.
LanceJoker: I don't have LED tail lights.
Jbondfl: It was covering it, apparently up until today. They were giving me a rent car on GM's dime. Today the dealer was covering it so I'm guessing they're not going back to GM for whatever reason.
Thanks for all the replies

I can only imagine how frustrating this must be - hope you get it figured out soon and put this problem behind you.

Jack: Thanks, me too...
Joker: No it doesn't seem like anything in particular induces the error. It might happen right after hitting a bump or just cruising down a smooth interstate at 70mph. I've hit some deep water at 60 too - no errors, in fact it's never errored out during rain.
thanks

What codes are tripped? The codes specify the exact wheel that's the problem. The sensor and hub/wheel bearing are one unit, that was replaced on my 99 but I was still
throwing codes for the same wheel. It turned out to be the wiring harness for that wheel to the computer that was bad.
