Parking Brake Reminder

WARNING: This page is about a different car, the 2003 Buick Regal and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

The BCM activates the park brake audible warning as requested by the IPC. The IPC sends a class 2 message to the BCM indicating the chime frequency (medium rate) and duration (continuous). The park brake warning sounds and the BRAKE indicator illuminates when the following occurs:

The ignition is on.
The vehicle is not in park. The IPC receives a class 2 message from the PCM indicating the gear position.
The IPC determines that the park brake is engaged (signal circuit is low). The IPC receives a class 2 message from the BCM indicating park brake status.
