Honda Accord/Civic/Prelude 1973-1983 Repair Guide

Power Door Locks

Print

The power door locking system consists of switches, actuators and relays. Control switch(es) are used to operate the system. Actuators are used to raise and lower the door lock buttons. These actuators are mounted inside the door assembly and are electrically operated once the switch is depressed. A control unit or functional relay is used to allow the system to regulate current, to function and to align all the actuators and switches with one another.

Some vehicles incorporate a central unlocking system that automatically unlocks all the doors of the vehicle once the key is inserted in the door from the outside of the vehicle.
