Principles of Operation

The Generic Electronic Module (GEM) communicates via the Medium Speed Controller Area Network (MS-CAN).

The GEM receives inputs and provides outputs for the power door lock system, exterior and interior lighting, front and rear wipers, and the warning chimes/lamps.

The GEM monitors the door lock/unlock switch inputs from the interior door lock switches. When the GEM receives an unlock/lock command from any door lock control switch, the module activates the door lock actuators. Refer to Doors, Hood and Trunk &/or Locks.

The GEM also controls the following remote lock/unlock features:

- Remote Keyless Entry (RKE) transmitter lock/unlock
