TCS Thermal Shutdown Mode

During prolonged Traction Control System (TCS) operation, brake lining temperatures may rise to a higher than desired level and the lining wear rate may increase. For this reason, the TCS system incorporates a brake thermal model which estimates brake temperatures during braking and TCS operation. The program calculates potential brake temperature based on time vs. amount of and duration of TCS brake applications. If the brakes or TCS modulator reach a potential over-temperature condition the TCS modulator is disabled but the Powertrain Control Module (PCM) will still control the adjuster assembly and spark control. If the adjuster assembly reaches a potential over-temperature condition the TCS system will disable. The amber TCS warning indicator will turn on and TCS will remain disabled until the brake linings are cooled to the proper temperature. The TCS system will automatically re-enable at this time. No Diagnostic Trouble Code (DTC)(s) will be stored. Normally TCS will not disable during a traction event, but if the maximum temperature threshold is reached, it will disable.
