CIRCUIT DESCRIPTION
When park brake input circuit 1134 to Body Control Module (BCM) is grounded (as when parking brake is applied), BCM will turn on brake telltale lamp by sending a serial data message to the Instrument Panel Cluster (IPC). If vehicle is moving greater than 10 km/h (6 mph) and park brake input to the BCM is grounded, BCM will sound the warning chime to notify the driver parking brake is applied.

DTC SET CONDITIONS
^ Ignition switch in RUN position
^ Vehicle speed greater than 10 km/h (6 mph)
^ Circuit 1134 grounded

DIAGNOSTIC AIDS
^ Verify that parking brake is fully disengaged.
