In system of the central blocking the executive mechanisms of locks installed in each door are used. The system consists of switches, executive mechanisms and electric conducting (see rice. An arrangement of elements of system of the central blocking of locks on the car).
Door locks are run by the two-directed solenoids located in the doorway. Switches of the lock have two working situation: "is closed" and "is opened". These switches operate the relay which, in turn, gives tension to solenoids of the door lock.
For check of system of the central blocking move the switch of the door lock to both provisions and check that solenoids of locks during the work make the clicking sound.
If the clicking sound in solenoids is absent, check that tension moves to the switch. If tension is absent, check an electric chain between fuses and switches.
If tension on the switch moves, but the solenoid does not click, check short circuit of contacts of the switch in various provisions of the switch (see rice. The main switch and a condition of contacts of the switch at various provisions of the switch and rice. The switch of the central blocking and a condition of contacts at various provisions of the switch).
