PINPOINT TEST 3: THE PARKING BRAKE ON WARNING CHIME DOES NOT OPERATE CORRECTLYNormal Operation
The parking brake on warning chime warns that the parking brake is engaged when the vehicle is in motion. The parking brake warning chime sounds if the ignition key is in ON position, the parking brake is engaged, and the vehicle speed is greater than 5 km/h (3 mph). The instrument cluster receives the vehicle speed sensor (VSS) status from the powertrain control module (PCM) over the high speed controller area network (CAN) communication bus. The instrument cluster uses the ignition run/start position status to determine ignition key position. The instrument cluster monitors these messages and operates the chime when all 3 inputs are received.
This pinpoint test is intended to diagnose the following:
