I have a 98 Buick Lesabre Limited with 100,000 kilometers. Excellent car . The TRACTION CONTROL OFF light on the dash panel is coming on after driving a few kms, or on start up, and will not go out. If I shut the car off at an intersection and restart the car, the TRACTION CONTROL OFF LIGHT will stay off for awhile and then come back ON AGAIN and stay on. WHAT IS THIS TELLING ME ? ? thanks everybody for your answers !

Hello, To find out what is causing the light to come on you will have to have the system checked with a scanner. Once you get the code then you can diagnose and repair the system. Not all aftermarket scanners are capable of reading the anti-lock traction system. You may have to go to a GM dealer.

The traction control system has detected a fault and turned itself off. The system uses sensors at the drive wheels to detect slippage and lock the differential and provide extra traction for acceleration. While the fault light is on, the system is not ready to provide this capability.
The ABS system uses many of the same components to keep the wheels from slipping while braking, and faults often cause both systems to quit.
There are a few things the average person can check for and possible repair, but much of these systems require specialized diagnostics to repair.
