Description of the central locking system (central locking)

Three different central locking systems are available: single lock, double lock and double lock with infrared remote control.

Single lock

A single central locking system does not require a module. All four door lock motors (M19, M20, M21 and M22) connected electrically to each other. If one of the front doors is mechanically closed or opened, current is applied to the other three door lock motors and they are activated.

Double blocking

The double locking of the four doors functions similarly to the single locking. Tailgate/trunk lid motors (M39) can only be activated by double blocking.

To activate the double locking system, the key must first be brought into position within three seconds "unlock", and then to position "block". These signals come from the door lock switches (N94 and N95) to terminals 10V, 11V, 15V or 13V, 14V, 16V of the door blocking module (A28). The module turns on the system only if the corresponding terminals 8V, 6V, 7V and 5V are signaled "door-closed" from all door lock switches (N84, N85 and N86).

Door lock module (A28) controls door lock motors (M19, M20, M22) and engine tailgate/trunk lid (M39) on terminals 5A, 6A, 7A, 1B and 2B.

When the system is activated, the inner handles and the lever for opening the rear cover of the body are disconnected from the locking mechanism. An intermittent sound signal sounds connected to the 12V terminal of the door lock module (A28) control buzzer (BUT), indicating that the system is configured. If there is a fault, a long continuous beep sounds.


System operation indicator lamp, depending on the equipment, is built into the watch (A39) or in the on-board computer module (A37). When the ignition is turned on, the 20V terminal of the door lock module (A28) a signal is given and the indicator lamp lights up for five seconds. If there is a malfunction, the lamp is on for twenty seconds.

Current is supplied to the door blocking module through terminals 3A, 2A and 19C.

Door Lock Diagnostic Connector (D11) connected to terminal 17V of the door lock module (A28).

Infrared remote control

If the infrared sensor embedded in the key is pressed towards the infrared receiver (B34 and B35), to terminals 10, ЗС, 4С, 5С of the door blocking module (A28) a signal is given. As a result, the door lock motors are installed in the appropriate position.
