Parking Brake Reminder

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.
