Park Lamp Relay

WARNING: This page is about a different car, the 2002 Dodge Grand Caravan, 2002 Dodge Caravan, 2002 Chrysler Voyager, and 2002 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

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 of the FCM. This circuit is electronically controlled and continuously monitored for malfunctions.
