Remarks according to schemes of electric connections

In view of limitation of the place it is not possible to include in the present manual of the scheme of electric connections of systems of electric equipment of all considered models. For this reason only the most typical schemes allowing to understand in detail the maximum degree in the principle of action of the main systems of electric equipment and onboard consumers of the electric power are given below.

Are made by Privzdennye below the scheme of electric connections by the schematic principle when components of each contour communicate among themselves on the shortest way without a form of laying of an electrical wiring around the components and plaits located on the way of its following.

On the Nissan cars the single-wire scheme of turning on of devices of electric equipment is applied. To plus of power supplies consumers unite a wire, and to minus – through a body of the car or on weight. Such method allows to reduce number of wires and to simplify their installation. Connection with the mass of minus of power supplies reduces electrochemical corrosion of metal details of a body. In certain cases direct connection of the electric consumer with weight is not enough, and the consumer unites to weight an additional wire of usually brown color.

Supply voltage is brought to most of consumers via the ignition switch. Power-supply circuits of those knots of electric equipment which work can be required in any circumstances are always connected to the rechargeable battery, irrespective of the provision of a key in the ignition lock.

For connection of wires electric sockets with flat contacts are used.

For normal food of consumers the electric chain has to be closed, otherwise at it there will be electric current, for example, if to the electric motor of a screen wiper positive tension moves, it will not work until its electric chain is not connected to weight. In an electric chain switches, the relay, safety locks, measuring devices, electric motors and other consumers of the electric power can be connected. For the correct connection of consumers of the electric power contacts of electric sockets have the corresponding markings. Connection with the mass of the car is carried out or directly via the case of the consumer of the electric power or an additional wire.

Before starting service of components of onboard electric equipment, in order to avoid receiving electric shock, or ignition as a result of casual short circuit, it is necessary to disconnect a negative wire from the battery. Regularly check a condition of plaits of an electrical wiring and reliability of their fastening in intermediate clamps, collars and bindings. You watch that isolation of wires was not wiped at contact with the components located in the neighbourhood with a plait.

 The models of cars considered in the present manual are equipped with system of additional safety (SRS). Before starting performance of any works near the block of a safety cushion, a steering column or the dashboard, disconnect SRS in order to avoid getting injured at its casual operation (see the Section of the Safety cushion - the general information). It is easy to distinguish an electrical wiring of a chain of SRS on yellow color of isolation.


If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that you have the correct combination for input of the audio system in action!

Contact 30.
At this contact there is always positive tension of the accumulator. The wires connected to this contact have color, red or red with a strip.

Contact 31.
The contact connects to the mass of the car a wire of brown color.

Contact 15.
On this contact positive tension after inclusion of ignition moves. The wires connected to this contact have color, green or green with a strip.

Contact of X.
On contact tension after inclusion of ignition moves, however at inclusion of a starter tension is disconnected. It gives the chance at start of the engine to disconnect consumers of the electric power, unnecessary at this moment. High beam headlamps receive food also from this contact therefore at the turned-on driving beam and switching off of ignition there is an automatic switching to marker lights.

Colors of wires are designated by Latin letters.

If in designation of color of a wire there are several letters divided by a sign/, then the left group of letters points to primary color of a wire, and right – to color of a strip.

On the scheme all consumers of current and switches are represented in neutral situation.
