Important: in the beginning disconnect from the pump многоштырьковый (ые) a socket () with thin wires – towards the end of a socket with a thick wire (current giving). Remove a cover 12-shtyrkovogo a socket Check of a switching element at doors of the driver: connect a control lamp to a socket between contact of a green/dark blue wire and weight of a body.

Check of a switching element in the luggage carrier lock: in the disconnected socket of the pump connect a control lamp between contact of a dark blue/red wire and «+» the accumulator. The control lamp should burn constantly if the luggage carrier lock opens a key. In this case disconnecting contact of a switching element is perfectly in order. If the lamp does not light up, in the luggage carrier lock disconnecting contact or not conductivity in a bringing wire is faulty. Switch a control lamp: instead of a dark blue/red wire now one of contacts of a control lamp is connected to a grey/white wire. Other contact remains connected to «+» the accumulator. Close the lock of a luggage carrier a key. If the control lamp burns constantly while the key remains in position "is closed", closing contact of a switching element is perfectly in order.
