### 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 the parking brake is fully disengaged.

• | Inspect the wiring harness for damage. Check for broken or chaffed insulation.

• | Check for blockage preventing the parking brake from fully releasing.

• | If fault is suspected to be intermittent, wiggling the harness wiring may help in locating the fault.
