Central locking switch and contact status at different switch positions
The central locking system uses lock actuators installed in each door. The system consists of switches, actuators and electrical wiring (see fig. The location of the elements of the central locking system on the car).
The door locks are controlled by bi-directional solenoids located in the doors. The lock switches have two operating positions: "closed" And "open". These switches operate a relay which in turn supplies voltage to the door lock solenoids.
To test the central locking system, move the door lock switch to both positions and check that the lock solenoids make a clicking sound during operation.
If there is no clicking sound from the solenoids, check that voltage is being applied to the switch. If there is no voltage, check the electrical circuit between the fuses and switches.
If the switch is energized, but the solenoid does not click, check the contact closure of the switch in various positions of the switch (see fig. The main switch and the state of the switch contacts at various switch positions and fig. Central locking switch and contact status at different switch positions).
