Power Door' Locks
The vehicle security module controls the power door locks, keyless entry system and the memory locking feature on vehicles equipped with a sliding door. The lock and unlock operation is carried out by supplying ground to the vehicle security module from the door lock control switch. The normal path of the actuators is to ground through the vehicle security module. The door lock control switch will lock and unlock all doors by grounding the appropriate circuit to the vehicle security module. The vehicle security module then supplies power to the appropriate common actuator circuit to lock or unlock all doors.
The sliding door memory lock feature locks the sliding door in the event that a lock command was issued by the operator while the sliding door was open. Since the door lock actuators are located in the sliding door, power is supplied to the actuators through the contact plate. When the sliding door is opened, the circuit is also opened. If a lock command is issued through the remote transmitter or door lock control switches, and the sliding door is opened, the memory lock feature will remember the command, and re-issue the lock signal to the door lock actuators once the sliding door is closed.
