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 8 km/h (5 mph) and park brake input to the BCM is grounded, BCM will sound the warning chime to notify the driver parking brake is applied. In addition, DTC B0005 will set in current status until ground on circuit 1134 to BCM is removed. Once ground on circuit 1134 is removed, DTC B0005 will transition from current status to history status.
DTC SET CONDITIONS
^ Ignition switch in RUN position
^ Vehicle speed greater than 8 km/h (5 mph)
^ Circuit 1134 grounded (normal operation)
^ Park brake applied and vehicle speed greater than 8 km/h (5 mph)
DIAGNOSTIC AIDS
^ Inspect wiring harness for damage. Check for broken or chaffed insulation.
^ Check for blockage preventing parking brake from fully releasing.
^ If fault is suspected to be intermittent, wiggling harness wiring may help in locating fault.
