The Instrument Cluster controls the Interior/Courtesy Lamps. The Instrument Cluster activates the courtesy lamps when either a Dome Lamp switch is turned on or a door is opened. The Instrument Cluster also monitors the output of the Glove Box and Map lamps. The Cargo lamps are controlled by the Instrument Cluster, it receives an output message from the Headlamp switch to turn on the lamps. The Instrument Cluster provides battery protection by shutting down the interior lamps when a door or courtesy/map lamp is left on or open.
