Miscellaneous Functions

^ 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. The BCM then communicates the information to the Instrument Cluster and Powertrain Control Module (PCM) via the Class 2 serial data link.
