Park Brake

When the park brake input circuit 1134 to the BCM is grounded (as when the parking brake is applied), the BCM will turn on the brake telltale by sending a serial data message to the Instrument Panel Cluster (IPC).

If the vehicle is moving at greater than 3 mph and the park brake input to the BCM is grounded, the BCM will sound the warning chime to notify the driver the parking brake is applied. DTC B0005 - Park Brake Switch Circuit Low will set under these conditions.
