Power Door Locks/Remote Keyless Entry: Notes
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 Instrument Cluster in response to the door lock switches or the RKE module directly controls the power door lock motors. The Instrument Cluster monitors the activation of the door lock motors and will set diagnostic trouble codes when there is an open or short condition. When there is a lock or unlock input from a switch or RKE command, the Instrument Cluster will activate the appropriate driver for 300 milliseconds. If a lock or unlock switch remains active, the request will be ignored until the switch transitions back to off. The lock switches are resistive multiplexed input devices hardwired to the Instrument Cluster.
