Park Lamp Relay

WARNING: This page is about a different car, the 2004 Dodge Pickup and 2004 Dodge Cab & Chassis. 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 instrument cluster. The instrument cluster sends a PCI bus request to the FCM to actuate the park lamp relay. The park lamp relay is then actuated through the low side control circuit. This circuit is electronically controlled and continuously monitored for malfunctions.
