The uniform lock – general information and check of serviceability of functioning

The device consists of switches of management, door activators, the control unit and connecting electroconducting. Problem diagnostics of the lock is limited to checks of a condition of contact connections of an electric chain and serviceability of operation of door activators. As in system ис

пользован the electronic control unit, complete diagnostics of its refusals can be made only with use of the special equipment in the conditions of a car-care center workshop. The control unit is located the uniform lock under the dashboard, to the right of the assembly block of safety locks.

Functioning of the uniform lock occurs at the expense of operation of the two-forked electromagnets located in the doorway of the car. The switch of management has two situation: Are LOCK and OPENLY. At activation the switch sends a grounding signal on the control unit door locks therefore there is the corresponding switching of activators. Depending on a starting position of the switch at its switching the control unit simply changes polarity of a current submitted on electromagnets.
Some models can be equipped with the anticreeping system included in structure of the uniform lock of the car. If to find a system cause of failure during carrying out listed below checks it is not possible, drive away the car for more complete diagnostics on car repair shop.

PERFORMANCE ORDER

1. First of all always check a condition of protection of a contour. Remember that on some models the chain of the uniform lock is protected by a combination of breakers and safety locks.
2. Popereklyuchayte management switches in both directions at the muffled engine. Listen to the clicks accompanying operation of electromagnets.

3. Check conductivity of switches in both of them provisions (see an accompanying illustration and the table below). Defective switches are subject to replacement.

4. Check conductivity of electroconducting on a chain site between switches, the control unit and electromagnets of activators. Execute repair of the damaged conducting.
5. Check serviceability of grounding of switches and the control unit.

6. At refusal only one of activators remove the panel of an internal upholstery from the corresponding door (see. Chapter the Body) also check serviceability of giving of tension on an executive electromagnet, switching the management switch. One of wires should запитываться in one of positions of the switch, the second – in other (see an accompanying illustration).

7. At serviceable giving of tension replace an electromagnet.
8. If tension does not move on the activator, check the corresponding site of a chain (between the activator and the control unit) on existence of breaks and short circuit.

More often damage of electroconducting occurs on plait sites between a door and a body of the car and is a consequence of the dynamic loadings enclosed to a plait at opening and closing of a door.
