PRECAUTIONS Description

INFOID:0000000005248677

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"

B

C

INFOID:0000000005248678

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 “SEAT BELT” of this Service Manual.

WARNING: • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which 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 the “SRS AIR BAG”.

• Do not 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.

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.

SGI841

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.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT < BASIC INSPECTION > lowing section illustrates ways to simulate the conditions/environment under which the owner experiences an electrical incident.

GI 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.

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.

N

O

P

SERVICE INFORMATION FOR ELECTRICAL INCIDENT < 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.

SGI842

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.

SGI843

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.

SGI844

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.

SGI845

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.

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.

D

There are two types of shorts.

SHORT

• SHORT CIRCUIT

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

• SHORT TO GROUND

When a circuit contacts a ground source and grounds the circuit.

NOTE: Refer to GI-33, "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.

G

J 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.

• 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 continuity: 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.

Revision: 2009 August

GI-40

2010 FX35/FX50

SERVICE INFORMATION FOR ELECTRICAL INCIDENT < BASIC INSPECTION > • When inspecting a ground connection follow these rules: - Remove the ground bolt or screw.

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

- Clean as required to assure good contact.

- Reinstall bolt or screw securely.

B - 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.

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

D

H SGI853

I

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.

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

F

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 “SEAT BELT” of this Service Manual.

WARNING: • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which 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 the “SRS AIR BAG”.

• Do not 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.

G

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

L

INFOID:0000000005245100

WARNING: • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT 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 Necessary for Steering Wheel Rotation after Battery Disconnect INFOID:0000000005245101

NOTE: • Before removing and installing any control units, first turn the push-button ignition switch to the LOCK position, then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both battery cables.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.

3.

4.

5.

6.

Connect both battery cables.

NOTE: Supply power using jumper cables if battery is discharged.

Turn the push-button ignition switch to ACC position.

(At this time, the steering lock will be released.)

Disconnect both battery cables. The steering lock will remain released with both battery cables disconnected and the steering wheel can be turned.

Perform the necessary repair operation.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering wheel will lock when the push-button ignition switch is turned to LOCK position.)

Perform self-diagnosis check of all control units using CONSULT-III.

Draining Engine Coolant

INFOID:0000000005245102

Drain engine coolant and engine oil when the engine is cooled.

Disconnecting Fuel Piping

INFOID:0000000005245103

• Before starting work, check that no fire or spark producing items are in the work area.

• Release fuel pressure before disconnecting and disassembly.

• After disconnecting pipes, plug openings to stop fuel leakage.

Removal and Disassembly

INFOID:0000000005245104

• When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or uninstructed operations.

• Exercise maximum care to avoid damage to mating or sliding surfaces.

• Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins, check that dowel pins are installed in the original position.

• Cover openings of engine system with a tape or equivalent, if necessary, to seal out foreign materials.

• Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.

• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be used in the step.

Inspection, Repair and Replacement

INFOID:0000000005245105

Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and replace if necessary.

Assembly and Installation

INFOID:0000000005245106

• Use torque wrench to tighten bolts or nuts to specification.

• When tightening bolts and nuts, as a basic rule, equally tighten in several different steps starting with the ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified, do exactly as specified.

• Replace with new gasket, packing, oil seal or O-ring.

• Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins, check that dowel pins are installed in the original position.

• Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for any restriction and blockage.

• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.

Before assembly, oil sliding surfaces well.

• Release air within route when refilling after draining engine coolant.

• After repairing, start the engine and increase engine speed to check engine coolant, fuel, engine oil, and exhaust gases for leakage.

COMPRESSION PRESSURE [VQ35HR] < PERIODIC MAINTENANCE > â&#x20AC;˘ If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole of the cylinder to re-check it for compression.

- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check piston rings and replace if necessary.

- If the compression pressure remains at low level despite the addition of engine oil, valves may be malfunctioning. Check valves for damage. Replace valve or valve seat accordingly. â&#x20AC;˘ If two adjacent cylinders have respectively low compression pressure and their compression remains low even after the addition of engine oil, cylinder head gaskets are leaking. In such a case, replace cylinder head gaskets.

INSPECTION AFTER INSTALLATION Inspection for Leakage

E

The following are procedures for checking fluids leakage, lubricates leakage.

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to MA-12, "Fluids and Lubricants".

• Use procedure below to check for fuel leakage.

- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.

- Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

NOTE: If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise will stop after hydraulic pressure rises.

• Warm up engine thoroughly to check there is no leakage of fuel, or any oil/fluids including engine oil and engine coolant.

• Bleed air from lines and hoses of applicable lines, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.

INSPECTION AFTER INSTALLATION Inspection for Leakage The following are procedures for checking fluids leakage, lubricates leakage and exhaust gases leakage.

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to MA-12, "Fluids and Lubricants".

• Use procedure below to check for fuel leakage.

- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.

- Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

• Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including engine oil and engine coolant.

• Bleed air from lines and hoses of applicable lines, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.
