Park Brake Warning

The body control module (BCM) activates the park brake audible warning with the associated chime frequency at a fast rate and at a continuous duration. The park brake warning sounds and the brake system indicator illuminates when the following occurs:

• The ignition is ON.
• The vehicle is not in park or neutral. The BCM receives a class 2 message from the PCM indicating the gear position.
• The BCM determines that the park brake is engaged and the signal circuit is low. The BCM sends a class 2 message to the IPC requesting illumination of the brake system indicator.
