Cause of DTC

The microprocessor-based electronic Driver Door Module (DDM) contains logic circuits that monitor various hard wired low current, multiplexed inputs from the power window, power lock, power mirror and memory switches. The program logic within the DDM allows the microprocessor to prioritize all inputs and then determine the tasks it needs to perform. These tasks are then completed either by controlling hard wired outputs to the various motors, actuators or lamps on its own or by sending electronic message requests over the CAN-IHS Bus to the appropriate electronic module in the vehicle.
