Notes on electrical connection diagrams
Due to space limitations, it is not possible to include in this Manual the electrical connection diagrams of the electrical equipment systems of all the models under consideration. For this reason, only the most typical diagrams are provided below, allowing you to understand in the greatest possible detail the operating principle of the main electrical equipment systems and on-board consumers of electrical energy.
The electrical connection diagrams below are based on the schematic principle, where the components of each circuit are connected to each other along the shortest path, without taking into account the shape of the wiring around the components and harnesses located along its path.
Nissan cars use a single-wire connection scheme for electrical equipment. Consumers are connected to the positive terminal of power sources by a wire, and to the negative terminal through the car body or to the ground. This method allows to reduce the number of wires and simplify their installation. Connecting the negative terminal of power sources to the ground reduces electrochemical corrosion of metal body parts. In some cases, direct connection of the electrical consumer to the ground is not enough, and the consumer is connected to the ground by an additional wire, usually brown.
Power supply to most consumers is supplied via the ignition switch. The power supply circuits of those electrical equipment units whose operation may be required under any circumstances are always connected to the battery, regardless of the position of the key in the ignition switch.
Electrical connectors with flat contacts are used to connect wires.
For normal power supply of consumers, the electric circuit must be closed, since otherwise there will be electric current in it, for example, if a positive voltage is supplied to the windshield wiper motor, it will not work until its electric circuit is connected to the ground. Switches, relays, fuses, measuring devices, electric motors and other consumers of electric power can be connected to the electric circuit. For the correct connection of consumers of electric power, the contacts of the electrical connectors have the appropriate markings. The connection to the ground of the car is carried out either directly through the body of the consumer of electric power or by an additional wire.
Before servicing on-board electrical components, to avoid electrical shock or fire from an accidental short circuit, disconnect the negative battery cable. Regularly inspect the condition of the wiring harnesses and the reliability of their fastening in intermediate clamps, clamps and strapping. Make sure that the insulation of the wires does not rub off when in contact with components located next to the harness.
Warning! The models of vehicles covered in this manual are equipped with a supplemental restraint system (SRS). Before performing any work near the air bag unit, steering column or instrument panel, turn off the SRS to avoid injury from accidental deployment (see section Airbags - General Information). The SRS circuit wiring is easily identified by the yellow color of the insulation.
If your car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!
Contact 30. This contact always has positive battery voltage. The wires connected to this contact are red or red with a stripe.
Contact 31. The contact is connected to the vehicle ground with a brown wire.
Contact 15. This contact is supplied with positive voltage after the ignition is turned on. The wires connected to this contact are green or green with a stripe.
Contact X. The contact is supplied with voltage after the ignition is turned on, but when the starter is turned on, the voltage is disconnected. This makes it possible to turn off unnecessary consumers of electricity at this moment when starting the engine. The high beam headlights also receive power from this contact, so when the high beam is on and the ignition is turned off, an automatic switch to the parking lights occurs.
The colors of the wires are indicated by Latin letters.
If the wire color designation contains several letters separated by the / sign, then the left group of letters indicates the main color of the wire, and the right group indicates the color of the stripe.
In the diagram, all current consumers and switches are shown in the neutral position.
