Brake Pedal Input Circuit Failure

Cause of DTC

The ABS module receives the brake pedal position switch signal from the Smart Junction Box (SJB) along the High Speed Controller Area Network (HS-CAN) bus. The ABS module compares the brake pedal position message to the signal from the brake pressure transducer (internal to the ABS module). If the brake pedal position message does not agree with the brake pressure signal, DTC B1483 will set.
