B3152 GMC Description
The switch that failed and generated the Diagnostic Trouble Code (DTC) is wired to either the Driver Door Switch Assembly (DDSA) or the Passenger Front Door Module (PDM). When a door lock switch is activated to the Lock or Unlock function, the DDSA or PDM receives the switch input and sends the information on, via the Serial Data Class 2 communications line, to the Rear Integration Module (RIM), which is the master of all lock operations. If the RIM determines that the message is a valid request and conditions are correct for a door lock function to occur, it sends its OK back to all the door modules to Lock or Unlock the doors. Each door module supplies power and ground to its associated lock actuator to Lock or Unlock the associated door.
