Driver Door Switch Assembly (DDSA)

The DDSA receives direct inputs from the driver's door lock switch, processes this information, and then sends a request message to the Rear Integration (RIM) Module via the Serial Data Class 2 line. The RIM receives the request message and examines it for lockout prevention criteria. If the conditions are proper, the RIM sends a lock or unlock command message back to each of the door modules over the Serial data Class 2 line. The door modules also use the Serial Data Class 2 line to communicate with other vehicle system modules. Power to the DDSA is supplied directly by the Drivers Door Module (DDM) Ground is supplied by a separate circuit.
