• If an aluminum wire is damaged (e.g. broken), never perform the repair method for copper wires (soldering).

• Never perform electrotap for connecting broken aluminum wires.

• To secure the wire fixing strength (a force to protect aluminum wire from being disconnected from crimp terminal) and electrical conductivity, always use the dedicated harness repair kit and caulking tool [SST: KV99112600] when repairing broken wires.

HOW TO DISTINGUISH ALUMINUM WIRES

Wiring color: Lavender (Color code: LA)

HOW TO REPAIR BROKEN WIRES

1. Insert heat shrinkable tube (2) into the target aluminum wire (1)

beforehand.

2. Strip wire terminal approximately 10 mm and insert it into crimp

terminal (3).

CAUTION:

Check wire size and use appropriate crimp terminal.

PRECAUTION

PRECAUTIONS

Description INFOID:0000000010106228

Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual section.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEA T BELT” of this Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

INFOID:0000000010106229

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Precaution for Procedure without Cowl Top Cover INFOID:0000000010106230

When performing the procedure after removing cowl top cover , cover the lower end of windshield with urethane, etc to prevent damage to windshield.

• Install the xenon bulb securely. (Insufficient bulb socket installation may melt the bulb, the connector, the housing, etc. by high-voltage leakage or corona discharge.)

• Never perform HID circuit inspection with a tester.

• Never touch the xenon bulb glass with hands. Never put oil and grease on it.

• Dispose of the used xenon bulb after packing it in thick vinyl without breaking it.

• Never wipe out dirt and contamination with organic solvent (thinner, gasoline, etc.).

Precautions for Removing of Battery Terminal INFOID:0000000010106232

• When removing the 12V battery terminal, turn OFF the ignition switch and wait at least 30 seconds.

NOTE:

ECU may be active for several tens of seconds after the ignition switch is turned OFF. If the battery terminal is removed before ECU stops, then a DTC detection error or ECU data corruption may occur.

• For vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON the ignition switch.

NOTE:

If the ignition switch is turned ON with any one of the terminals of main battery and sub battery disconnected, then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:

The removal of 12V battery may cause a DTC detection error.

SEF289H

General Precautions INFOID:0000000010106233

• Do not operate the engine for an extended period of time without proper exhaust ventilation. Keep the work area well ventilated and free of any inflammable materials. Special care should be taken when handling any inflammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials. Do not smoke while working on the vehicle.

SGI285

• Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent the vehicle from moving. After jacking up the vehicle, support the vehicle weight with safety stands at the points designated for proper lifting before working on the vehicle. These operations should be done on a level surface.

• When removing a heavy component such as the engine or transaxle/transmission, be careful not to lose your balance and drop them. Also, do not allow them to strike adjacent parts, especially the brake tubes and master cylinder.

Engine Oils INFOID:0000000010106237

Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.

HEALTH PROTECTION PRECAUTIONS

• Avoid prolonged and repeated contact with oils, particularly used engine oils.

• Wear protective clothing, including impervious gloves where practicable.

• Do not put oily rags in pockets.

• Avoid contaminating clothes, particularly underpants, with oil.

• Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regularly.

• First aid treatment should be obtained immediately for open cuts and wounds.

• Use barrier creams, applying them before each work period, to help the removal of oil from the skin.

• Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed.

• Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.

• If skin disorders develop, obtain medical advice without delay.

• Where practical, degrease components prior to handling.

• Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face shields; in addition an eye wash facility should be provided.

ENVIRONMENTAL PROTECTION PRECAUTIONS

Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste disposal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal facilities. It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.

HOW TO PROBE CONNECTORS

• Connector damage and an intermittent connection can result from improperly probing of the connector during circuit checks.

• The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the connector, follow the procedures below using a “T” pin. For the best contact grasp the “T” pin using an alligator clip.

Probing from Harness Side

Standard type (not waterproof type) connector should be probed from harness side with “T” pin.

• If the connector has a rear cover such as a ECM connector, remove the rear cover before probing the terminal.

• Do not probe waterproof connector from harness side. Damage to the seal between wire and connector may result.

Probing from Terminal Side

FEMALE TERMINAL

• There is a small notch above each female terminal. Probe each terminal with the “T” pin through the notch. Do not insert any object other than the same type male terminal into female terminal.

4. While moving the connector, check whether the male terminal can be easily inserted or not.

• If the male terminal can be easily inserted into the female ter-

minal, replace the female terminal.

Waterproof Connector Inspection

If water enters the connector, it can short interior circuits. This may lead to intermittent problems. Check the following items to maintain the original waterproof characteristics.

SEL272V

SEL273V

RUBBER SEAL INSPECTION

• Most waterproof connectors are provided with a rubber seal

between the male and female connectors. If the seal is missing, the waterproof performance may not meet specifications.

• The rubber seal may come off when connectors are disconnected.

Whenever connectors are reconnected, check the rubber seal is properly installed on either side of male or female connector.

WIRE SEAL INSPECTION

• The wire seal must be installed on the wire insertion area of a

waterproof connector. Be sure that the seal is installed properly.

Terminal Lock Inspection

Check for unlocked terminals by pulling wire at the end of connector. An unlocked terminal may create intermittent signals in the circuit.

lowing section illustrates ways to simulate the conditions/environment under which the owner experiences an electrical incident.

The section is broken into the six following topics:

• Vehicle vibration

• Heat sensitive

• Freezing

• Water intrusion

• Electrical load

• Cold or hot start up Get a thorough description of the incident from the customer. It is important for simulating the conditions of the problem.

VEHICLE VIBRATION

The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustration.

Connector & Harness

Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently shake each connector and harness while monitoring the system for the incident you are trying to duplicate. This test may indicate a loose or poor electrical connection.

Hint

Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector terminals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on related connectors in the system.

Sensor & Relay

Gently apply a slight vibration to sensors and relays in the system you are inspecting. This test may indicate a loose or poorly mounted sensor or relay.

SGI839

Engine Compartment

There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the things to check for are:

• Connectors not fully seated.

• Wiring harness not long enough and is being stressed due to engine vibrations or rocking.

• Wires laying across brackets or moving components.

• Loose, dirty or corroded ground wires.

• Wires routed too close to hot components. To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground Inspection described later.) First check that the system is properly grounded. Then check for loose connection by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the wiring for continuity.

Behind the Instrument Panel

An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehicle vibration can aggravate a harness which is routed along a bracket or near a screw.

Under Seating Areas

GI-48

Page 56

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

Revision: 2013 November 2014 Q70

< BASIC INSPECTION >

An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides) during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or pinching.

HEAT SENSITIVE

• The customer's concern may occur during hot weather or after car

has sat for a short time. In such cases you will want to check for a heat sensitive condition.

• To determine if an electrical component is heat sensitive, heat the

component with a heat gun or equivalent.

CAUTION:

Never heat components above 60°C (140°F).

• If incident occurs while heating the unit, either replace or properly

insulate the component.

FREEZING

• The customer may indicate the incident goes away after the car

warms up (winter time). The cause could be related to water freezing somewhere in the wiring/electrical system.

• There are two methods to check for this. The first is to arrange for

the owner to leave his car overnight. Check it will get cold enough to demonstrate his complaint. Leave the car parked outside overnight. In the morning, do a quick and thorough diagnosis of those electrical components which could be affected.

• The second method is to put the suspect component into a freezer

long enough for any water to freeze. Reinstall the part into the car and check for the reoccurrence of the incident. If it occurs, repair or replace the component.

WATER INTRUSION

The incident may occur only during high humidity or in rainy/snowy weather. In such cases the incident could be caused by water intrusion on an electrical part. This can be simulated by soaking the car or running it through a car wash.

CAUTION:

Never spray water directly on any electrical components.

JPAIA0733GB

SGI843

ELECTRICAL LOAD

The incident may be electrical load sensitive. Perform diagnosis with all accessories (including A/C, rear window defogger, radio, fog lamps) turned on.

COLD OR HOT START UP

On some occasions an electrical incident may occur only when the car is started cold, or it may occur when the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to make a proper diagnosis.

Circuit Inspection

INFOID:0000000010101906

DESCRIPTION

• In general, testing electrical circuits is an easy task if it is approached in a logical and organized method. Before beginning it is important to have all available information on the system to be tested. Also, get a thorough understanding of system operation. Then you will be able to use the appropriate equipment and follow the correct test procedure.

• You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring harness or electrical component to do this.

OPEN A circuit is open when there is no continuity through a section of the circuit.

There are two types of shorts.

SHORT

• SHORT CIRCUIT

• SHORT TO GROUND When a circuit contacts a ground source and grounds the circuit.

When a circuit contacts another circuit and causes the normal resistance to change.

NOTE:

Refer to GI-44, "

How to Check Terminal" to probe or check terminal.

TESTING FOR “OPENS” IN THE CIRCUIT

Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your working knowledge of the system.

SGI846-A

Continuity Check Method

The continuity check is used to find an open in the circuit. The digital multimeter (DMM) set on the resistance function will indicate an open circuit as over limit (no beep tone or no ohms symbol). Check to always start with the DMM at the highest resistance level. To help in understanding the diagnosis of open circuits, please refer to the previous schematic.

• Disconnect the battery negative cable.

• Start at one end of the circuit and work your way to the other end. (At the fuse block in this example)

• Connect one probe of the DMM to the fuse block terminal on the load side.

• Connect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point A)

• Connect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the circuit has good continuity . If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point B)

• Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point C)

Any circuit can be diagnosed using the approach in the previous example.

Voltage Check Method

To help in understanding the diagnosis of open circuits please refer to the previous schematic. In any powered circuit, an open can be found by methodically checking the system for the presence of voltage. This is done by switching the DMM to the voltage function.

• Connect one probe of the DMM to a known good ground.

• Begin probing at one end of the circuit and work your way to the other end.

• With SW1 open, probe at SW1 to check for voltage. voltage: open is further down the circuit than SW1.

no voltage: open is between fuse block and SW1 (point A).

• Close SW1 and probe at relay. voltage: open is further down the circuit than the relay. no voltage: open is between SW1 and relay (point B).

• Close the relay and probe at the solenoid. voltage: open is further down the circuit than the solenoid. no voltage: open is between relay and solenoid (point C).

Any powered circuit can be diagnosed using the approach in the previous example.

TESTING FOR “SHORTS” IN THE CIRCUIT

To simplify the discussion of shorts in the system, please refer to the following schematic.

SGI847-A

Resistance Check Method

• Disconnect the battery negative cable and remove the blown fuse.

• Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the fuse.

• Connect one probe of the DMM to the load side of the fuse terminal. Connect the other probe to a known good ground.

• With SW1 open, check for continuity. continuity: short is between fuse terminal and SW1 (point A). no continuit: short is further down the circuit than SW1.

• Close SW1 and disconnect the relay. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity. continuity: short is between SW1 and the relay (point B). no continuity: short is further down the circuit than the relay.

• Close SW1 and jump the relay contacts with jumper wire. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity . continuity: short is between relay and solenoid (point C). no continuity: check solenoid, retrace steps.

Voltage Check Method

• Remove the blown fuse and disconnect all loads (i.e. SW1 open, relay disconnected and solenoid disconnected) powered through the fuse.

• Turn the ignition switch to the ON or START position. Verify battery voltage at the battery + side of the fuse terminal (one lead on the battery + terminal side of the fuse block and one lead on a known good ground).

• With SW1 open and the DMM leads across both fuse terminals, check for voltage. voltage: short is between fuse block and SW1 (point A). no voltage: short is further down the circuit than SW1.

• With SW1 closed, relay and solenoid disconnected and the DMM leads across both fuse terminals, check for voltage. voltage: short is between SW1 and the relay (point B). no voltage: short is further down the circuit than the relay.

• With SW1 closed, relay contacts jumped with fused jumper wire check for voltage. voltage: short is down the circuit of the relay or between the relay and the disconnected solenoid (point C). no voltage: retrace steps and check power to fuse block.

GROUND INSPECTION

• Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted resistance. This unwanted resistance can change the way a circuit works.

• Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even when the ground connection looks clean, there can be a thin film of rust on the surface.

GI-51

Page 59

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

Revision: 2013 November 2014 Q70

< BASIC INSPECTION >

• When inspecting a ground connection follow these rules:

- Remove the ground bolt or screw.

- Inspect all mating surfaces for tarnish, dirt, rust, etc.

- Clean as required to assure good contact.

- Reinstall bolt or screw securely.

- Inspect for “add-on” accessories which may be interfering with the ground circuit.

- If several wires are crimped into one ground eyelet terminal, check for proper crimps. Check all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one eyelet check no ground wires have excess wire insulation.

• For detailed ground distribution information, refer to “Ground Distribution” in PG section.

SGI853

VOLTAGE DROP TESTS

• Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage drop in a circuit is caused by a resistance when the circuit is in operation.

• Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire will give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire is not able to carry the current. The single strand will have a high resistance to the current. This will be picked up as a slight voltage drop.

• Unwanted resistance can be caused by many situations as follows:

- Undersized wiring (single strand example)

- Corrosion on switch contacts

- Loose wire connections or splices.

• If repairs are needed always use wire that is of the same or larger gauge.

Measuring Voltage Drop — Accumulated Method

• Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the DMM should be closer to power and the negative lead closer to ground.

• Operate the circuit.

• The DMM will indicate how many volts are being used to “push” current through that part of the circuit.

GI-52

Page 60

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

Revision: 2013 November 2014 Q70

< BASIC INSPECTION >

Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.

SGI974

Measuring Voltage Drop — Step-by-Step

• The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in “Computer Controlled Systems”).

• Circuits in the “Computer Controlled System” operate on very low amperage.

• The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the system. Such resistance variation may be caused by poor connection, improper installation, improper wire gauge or corrosion.

• The step by step voltage drop test can identify a component or wire with too much resistance.

PRECAUTION

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

WARNING:

Always observe the following items for preventing accidental activation.

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precautions for Removing of Battery Terminal INFOID:0000000010282465

INFOID:0000000010282464

ADP

• When removing the 12V battery terminal, turn OFF the ignition

switch and wait at least 30 seconds.
