Fig. 15.62. An arrangement of components of system of the central blocking of locks: 1 – the ignition lock; 2 – block ECU located from outside of the forward passenger; 3 – the switch of blocking of the locks, located at doors of the forward passenger; 4 – safety locks and the relay стеклоподъемников in the block of safety locks and the relay; 5 – the switch of blocking of the locks, located at doors of the driver; 6 – the lock and the switch of the central blocking of forward doors; 7 – the lock and the switch of the central blocking of back doors; 8 – the lock of the central blocking of a door of a luggage space
The system of the central blocking of locks uses modulators of locks of the door established in each door (fig. 15.62
). The system consists of switches, modulators, the block of management and the electric chains connecting all components, and also the transmitter and the remote control receiver.
Blocking of locks is made by the reversive solenoids located in the doorway. Switches of locks have two working positions: it is closed and is opened. By pressing of the switch from it the signal on the block of management opening or closing locks of doors arrives.
On some models the system of blocking of locks is united with anticreeping system.
Check of system of the central blocking of locks make as follows:
If blocking of locks does not work, first of all check up integrity of a safety lock. On some models for protection of system of blocking of locks use also protection automatic machines.
At the switched off engine, pressing the switch of blocking of locks, listen, whether solenoids work. At operation they publish a characteristic clicking sound.
If solenoids do not work, remove and check up the switch.
Check up a condition of an electric chain between the switch, the block of management and solenoids.
Also check up reliability of connection to "weight" of the switch and the management block.
If one solenoid does not work only, remove an upholstery of a door and check up, whether moves pressure to the solenoid at switch activation. On one of wires there should be a pressure at lock blocking, and on other wire — at деблокировке the lock.
If pressure moves, and the solenoid does not work, replace it.
If pressure does not move on the solenoid, check up the relay and an electric chain between the solenoid and the management block.
