C0163 CHEVROLET Description

Antilock Brake System (ABS)/Traction Control System (TCS) Brake Switch/Sensor Circuit Low. The Body Control Module (BCM) receives a signal from the Brake Pedal Position (BPP) sensor. The BCM illuminates the stop lamps by applying battery positive voltage to the stop lamp supply voltage circuit. The Electronic Brake Control Module (EBCM) receives a voltage input from the stop lamp supply voltage circuit to determine if the brake pedal is applied.
