Service ABS/Traction Control Gremlin
Help!
Gremlins are inhabiting the GR8C5! I need a wizard. She's a '97 with 6-sp, Z51, FE3.
At an outside temp of 37 F or less, when I hit a bump, the Service ABS and Service Traction Control icons light up and the DIC presents the message that there is service on same needed. If I turn off the engine and restart, the icons are off and the DIC is quiet until I hit another bump. For those familiar with the Michigan roads, bumps are everywhere. These aren't huge speed-bumps that cause the cd player to skip but Michigan-sized expansion joints that are everywhere.
Interestingly, when the outside temperature is in the 50's or above, there is no such warning or message. The obvious answer is to not drive when it's below 50. I've had the GR8C5 for two years now and she has had this issue since I've had her. I have replaced the brake fluid and bled the system. All other systems are fine as far as I know.
Anyone have such an adventure with their C5 and been able to figure it out?
Thanks to all ahead of time.

Re: Service ABS/Traction Control Gremlin (GR8C5)
had the same problem, could be a loose harness. you need to get the computer scanned and get the code for which wheel is giving off the code. I had the extd warranty and got mone sensor ($535), harness, and "brains replaced ($1160 parts total- 6 hrs labor). Most of the time it is a problem with the wires from the sensor to the control module that sits under the battery. I have mine back in the shop now because the light is on again after 6 months and they can't figure it out, they had my car 5 days, told me it was fixed and 5 min later the light was back on, so my lovely wife dropped it off again this AM
