Miscellaneous Functions

^ BRAKE indicator lamp control: The BCM controls the state of the BRAKE indicator lamp based on the status of the parking brake switch by sending a message to the instrument cluster via the Class II serial data link.
^ Fog lamp enable control. The BCM controls fog lamp operation, based on the status of the ignition switch.
^ Day/night mode sensing: The BCM determines the ambient light operating mode from the Daytime Running Lamp (DRL) control module. Then, it communicates this information to the instrument cluster and Powertrain Control Module (PCM) via the Class 2 serial data link.
