The system, installed on a part of the vehicle exhaust, is designed to simultaneously lock the locks of all doors when the driver's door lock is locked with a key or using the lock button

When you unlock the driver's door with the button or key, all other doors will also unlock.

It is possible to unlock the locks of the rear doors and the right front door separately using the lock buttons.

Each door is equipped with lock motor gearboxes, which combine a DC electric motor with excitation from permanent magnets and a rack-and-pinion gearbox.

Fig. 1. Scheme of the door lock system: 1 - mounting block; 2 - control unit; 3 - gearmotor for blocking the passenger door lock; 4 - gear motor for locking the rear door lock; 5 - gearmotor blocking the driver's lock; A - to power supplies; B - scheme of conditional numbering of plugs in the block of the control unit; C - scheme of conditional numbering of plugs in blocks of gear motors for blocking locks

The gearmotor 5 (Fig. 1) installed in the driver's door has a built-in switch, the contacts of which are switched when the lock button is moved or when the door lock drum is turned with the key.

When the switch contacts are closed, the electronic control unit 2 turns on all the gearmotors, which block the door locks through the rods.

When the contacts are opened, the locks are unlocked by gearmotors in the same way.

The control unit has an inertial switch that unlocks the doors when the car hits an obstacle during an accident.

If there is a malfunction in the system, check the fuse, wires and their connections, the control unit and gearmotors.

The control unit and gearmotors are not collapsible, and in case of failure they are replaced.

Data for checking the gearmotor

The force developed by the actuating element at a supply voltage of (13±0.1) V and at an ambient temperature of (25±10) °С, N, not less than 30

Consumed current at the above supply voltage, A, no more than 7
