Broadcast Message Originating Module Message Purpose
Headlamp switch status SCCM Indicates the headlamp switch position (or fault) to the BCM . When the position is indicated as the parking lamps on (or a fault), the BCM provides voltage to the parking lamps and headlamps.

Parking Lamps

The SCCM monitors the headlamp switch position and sends the headlamp switch status message over the communication network to the BCM to indicate the headlamp switch status (position or a fault with the headlamp switch).

The BCM turns the parking lamps and headlamps on if it loses communication with the SCCM , or if the SCCM detects a fault from the headlamp switch.

When the BCM receives input requesting the parking lamps on, one circuit provides voltage to all of the front parking lamps and a second circuit provides voltage to all of the rear parking lamps.
