Brake Switch Circuit Failure
The brake pedal switch is hard wired to the powertrain control module (PCM) supplying battery voltage when the brake pedal is applied. The PCM communicates with the ABS module via the high speed controller area network (HS-CAN) for the brake pedal switch position.
Possible Causes
- Brake pedal position/stop lamp switch
- ABS module
- Hydraulic control unit (HCU)
