System of locks with the central management

Elements of hoses of system of locks with the central management and their passage

1 – запорный an element of a door of the forward passenger;
2 – запорный an element of a back right door;
3 – запорный an element of a cover of a fuel tank;
4 – запорный an element of a cover of a luggage compartment;

5 – the pump;
6 – запорный an element of a back left door;
7 – запорный an element of a driver's door;
8 – one of vacuum pipelines.


On an illustration are shown запорный an element (1) systems of locks with the central management in a driver's door with the connecting tip (3) and a nagnetatelno-vacuum hose (4). Are Besides represented приводной a cable деблокировки doors (2) and the directing tyre window lifterа (5).


The pump (1) systems of locks with the central management is located at sedans and versatile persons under the right covering of a luggage carrier or a luggage compartment. On an illustration it is represented removed and lying on the bottom of a luggage compartment, the tip of the wires conducting to запорным to elements (3), already released from the cover (2) (that contacts have opened). The tip of giving of a food to the pump (4) remained established.

All doors, and also cover of a luggage carrier and fuel tank can be locked or unlocked turn of a key of a driver's door, or a door of the forward passenger, or a luggage carrier cover. A system basic element is the pump resulted by the electric motor. At key turn in a direction "Openly" the pump creates an elevated pressure because of what various elements of switching deblock the corresponding lock. On the contrary, at lock-out the lowered pressure is created, and switching elements block the lock.

 The help: feature of the lock of a cover of a luggage carrier: in vertical position of a key the luggage carrier is always closed – irrespective of system of locks. Thus luggage theft is prevented, for example, at a stop at a traffic light. In horizontal position the lock of a cover of a luggage carrier reacts together with all system of locks with the central management.

Check of system of locks with the central management

To unlock, and then to lock doors of the driver, the forward passenger and a luggage carrier cover.

 PERFORMANCE ORDER

  1. The system of locks with the central management should be activated in all three doors.
  2. After approximately 2 with all locks should be locked.
  3. If the pump works longer 5 with, it means that system негерметична – in this case the pump should work no more than 35 with, then it should be disconnected.

 The help: if the system of locks with the central management has given failure, it is possible to unlock and lock doors and a luggage carrier cover in the usual image. As it is possible to block door buttons.

Search of malfunctions electricians

If the pump does not work at a turn as a key in a driver's door, neither at doors of the forward passenger, nor in a door of a luggage compartment:

 PERFORMANCE ORDER

  1. To check up a safety lock (head Kuzovnaja electrosystem).
  2. To remove a covering in a luggage compartment behind on the right.
  3. To disconnect the multicontact tip from the pump.
  4. To remove a cover of the multicontact tip.
  5. To check up запорный an element of a driver's door: to connect a control lamp in the tip between contact of a green-dark blue wire and "weight" (case) of a body.
  6. The control lamp should burn constantly if the driver's door is open by a key. In this case opening contact запорного an element is perfectly in order.
  7. If the bulb does not light up, means, opening contact of a driver's door is faulty or the electric chain is interrupted.
  8. Now to switch a control lamp: a wire which went to "weight", it is necessary to throw on the positive plug of the storage battery. Other contact remains in the tip (contact of a green-dark blue wire).
  9. To lock a driver's door a key.
  10. If the control lamp burns now constantly, means, closing contact запорного an element is perfectly in order.
  11. If the lamp does not light up, but wires are whole are means that is faulty запорный an element.
  12. To check up запорный an element of a door of the forward passenger: to connect a control lamp in the removed tip of the pump between contact of a yellow-dark blue wire and "weight" (case) of a body.
  13. The control lamp should burn constantly if the door of the forward passenger is open by a key. In this case opening contact запорного an element is perfectly in order.
  14. If the lamp does not light up, means, opening contact of a door of the forward passenger is faulty or the electric chain is interrupted.
  15. Now to switch a control lamp: a wire which went to "weight", it is necessary to throw on a positive conclusion of the storage battery. Other contact remains in the tip (contact of a yellow-dark blue wire).
  16. To lock a door of the forward passenger a key.
  17. If the control lamp burns now constantly, means, closing contact запорного an element is perfectly in order.
  18. If the lamp does not light up also wires are whole, it means that is faulty запорный an element.
