The vehicle security module is on the international standards organization (ISO) communication network. The vehicle security module controls the power door lock system. The module monitors the door lock/unlock switch inputs from the interior door lock switches. When the module receives an unlock/lock command from any door lock control switch, the module will activate the door lock actuators. The module also controls the remote keyless entry (RKE) transmitter lock/unlock.
For additional information on the power door lock system, refer to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS .
