The uniform lock - general information and check of serviceability of functioning Operation of individual activators of locks of each of car doors is the basis for functioning of system. The system consists of switches of management, door activators and a connecting electrical wiring. Failure diagnostics of system is limited to checks of a condition of contact connections of an electric chain and serviceability of operation of door activators. Performance of deeper checks should be charged to specialists of car service.Functioning of the uniform lock happens due to operation of the bidirectional electromagnets located in the doorway of the car. The switch of management has two provisions: It is LOCKED and is OPENED. When squeezing the switch provides giving of food on the relay of control of activators of door locks therefore there is the corresponding switching of the last. Depending on a starting position of the relay gives tension of the corresponding polarity on electromagnets of activators. On some models the system of the uniform lock is equipped with the remote control and is combined with anticreeping system. Functioning of such system is controlled by the special electronic module of management. If it is not possible to establish a system cause of failure during the checks described below, address for consultations specialists of company car repair shops of the Nissan company. First of all always check a condition of the protection of a contour provided with a combination of safety locks and breakers of a chain. Popereklyuchayte switches of management in both directions at the killed engine. Listen to the clicks accompanying operation of electromagnets of door activators. In the absence of clicks check serviceability of giving of tension for switches. If giving of food is broken, check a condition of an electrical wiring on the site of a chain between the corresponding switch and the assembly block of safety locks. If food moves regularly, check serviceability of a condition of the switch (conductivity distribution). Replace faulty components. If the switch is serviceable, however clicks of the relay are not heard, check a condition of an electrical wiring between the corresponding switch and the relay. Make necessary recovery repair. If the relay is powered regularly, however does not give food on the door activator, check serviceability of grounding of its case. If grounding as it should be, replace the relay.
At correct giving of tension replace an electromagnet. If violation of giving of food takes place, check for break and short circuit an electrical wiring on the site of a chain between an electromagnet and the relay.
