Repair and car operation

The uniform lock and remote control system door activators – the general data and check of serviceability of functioning

The general information

In a basis of functioning of system operation of individual activators of locks of each of car doors is necessary. The system consists of switches of management, door activators and connecting electroconducting. The system problem diagnostics is limited to checks of a condition of contact connections of an electric chain and serviceability of operation of door activators. It is necessary to charge performance of deeper checks to experts of car-care centre. The block of management of system of the uniform lock is located under the panel of devices, to the right of the assembly block of safety locks/relays.

Functioning of the uniform lock occurs at the expense of operation of the two-forked electromagnets located in the doorway of the car. The management switch has two positions: it is locked and is opened. On the models of last years of release equipped with system of remote control, switches give out a signal on the module of management which, in turn, influences electromagnetic switches, or приводные electromotors of door-locks. Depending on a switch starting position there is a change of polarity of a food of activators. On models of earlier years of release switches are connected directly to electromagnets of door-locks.

On some models the system of the uniform lock is united with system of the anticreeping alarm system.

If to find the reason for refusal during described below checks it is not possible, the car should be driven away on a car repair shop.

Check

PERFORMANCE ORDER

1. First of all always check a condition of protection of a contour. On some models protection is provided with a combination of safety locks and chain breakers.
2. Попереключайте management switches in both directions at the muffled engine. Listen to the clicks accompanying operation of electromagnets of door activators.
3. In the absence of clicks check up serviceability of giving of pressure on switches. If food giving is broken, check up an electroconducting condition on a chain site between the corresponding switch and the assembly block of safety locks. If a food moves regularly, check up serviceability of a condition of the switch (conductivity distribution).
4. Replace switches conductivity in which is absent in both positions. If the switch is serviceable, however relay clicks is not audible, check up an electroconducting condition between the corresponding switch and an electromagnet. Make necessary regenerative repair.
5. Check up a condition of grounding of switches and the management block.
6. At refusal only one of activators remove the panel of an internal upholstery from a corresponding door of the car (the Body see the Head) and check up serviceability of giving of pressure on an executive electromagnet, switching the management switch. One of wires should запитываться in one of positions of the switch, the second – in other.
7. If a food moves regularly, replace an electromagnet.
8. If infringement of giving of a food takes place, check up on breakage and short circuit electroconducting on a chain site between an electromagnet and the relay, and also a condition actually the relay.

More often the wire breakage occurs on a site between a door and кузовной the panel.
