Exterior Lighting
The Headlamps are controlled by the Instrument Cluster. The Instrument Cluster is also referred to as a "Smart Cluster". It receives and sends messages to other modules through the PCI BUS circuit. The Headlamps are wired through the cluster and then go to the Fuse Block to the lamps. Each Headlamp has an independent fuse located in the Fuse Block. For vehicles equipped with Daytime Running Lamps, the DRL Module is integrated with the Instrument Cluster.
