Normal Operation and Fault Conditions

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

The BCM uses 2 normally-open switches, connected in series, to monitor the wear of the brake pads. As the brake pads wear, the switches close. Once fully closed, the BCM sends a message to the IPC to display a warning in the message center.
