C0038

DTC C0038 Brake Thermal Fault

Resulting Effects:
Excessive brake could result in degraded braking performance or possible damage to the rotors or brake pads.

Fail Action:
The TCS disabled lamp is turned on and TCS is inhibited as long as both driven wheel brake rotor temperatures are above the reenable calibrated value. If both of the rotor temperatures go below this calibration, then the TCS disabled lamp will be turned off and TCS is again enabled. This is a fully recoverable fault code.

Conditions for Clearing the DTC
^ C0038 could be set when either driven wheel thermal counter exceeds a calibrated value (300°C).
^ Thermal counters are incremented during base braking, ABS and TCS. If either driven wheel estimated brake rotor temperatures has exceeded the calibrated value during ABS or normal braking conditions, the code will not be set until the next TCS activation occurs.
^ The code will not be set and TCS will not be disabled if both rotor temperatures have cooled below a second calibrated value (275°C) before the next TCS activation. If either driven wheel brake rotor temperatures have exceeded the first calibrated value during TCS then the code will be set immediately, the Traction disable lamp will be turned on immediately but TCS will not be disabled until the completion of the TCS activation.
