Parking Lamp Relay: Description and Operation
The park lamp switch is a direct input to the BCM. The BCM sends a BUS message to the FCM informing it to turn ON the park lamp relay. The park
lamp relay is then powered through low side control on pin 13 of the FCM. This circuit is electronically controlled and continuously monitored for
malfunctions.
