Diagnostic Aids

WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

With TCS temporarily disabled, the EBCM continues calculating the brake rotor temperatures after the ignition is turned OFF. Turning ON the ignition again while TCS is temporarily disabled will not re-enable TCS.
The temperature is an estimate calculated by the EBCM.
Possible causes of this DTC are the following conditions:
- The brake usage is excessive.
- The TCS usage is excessive.
- The stoplamp switch is misaligned or damaged.
