Warning Light Illumination PatternINSPECTION
1) When warning lights or indicator lights do not illuminate in accordance with this illumination pattern, there must be an electrical malfunction.
2) When warning lights or indicator lights remain constantly OFF, check the combination meter circuit or CAN communication circuit.
3) When the electronic parking brake warning light (C6 model only) and hill hold indicator light do not go off, check the combination meter circuit, CAN communication circuit and electronic parking brake control module.
4) When the brake warning light does not go off, check the combination meter circuit, CAN communication circuit, electronic parking brake control module, and VDCCM&H/U.
5) After replacing the electronic parking brake control module, the brake warning light blinks. Make sure to perform the Force Sensor Calibration Mode and Clutch Sensor Calibration Mode. Scan Tool Testing and Procedures
6) When operation and release of the parking brake is repeated excessively, the brake warning light blinks and the parking brake switch operation may not be accepted for several tens of seconds; this is not malfunction, however.
