Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Principles of Operation
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 .
