PRECAUTIONS

PRECAUTIONS PFP:00001

Description AAS00009

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

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain
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 and SB section of this Service Man­ual.

WARNING:

● To avoid rendering the SRS inopera tive, which c ould increa se the risk of perso nal injury or dea th

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, inc luding incorrect removal and installation of the SRS, can lead to per-

sonal injury ca use d by unintentional ac tiv atio n o f the system. For remo va l of Spiral Cable and Air
Bag Module, see the SRS section.

● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed to in this

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

Precautions for NVIS/IVIS (NISSAN/INFINITI VEHICLE IMMOBILIZER SYSTEM ­NATS) (If Equipped)

NVIS/IVIS (N ATS) will immob il iz e the e ng i ne if s ome one tr i es to s tart it wit h ou t th e r e gist e re d ke y o f NV I S/ IVI S
(NATS).
Both of the originally supplied ignition key IDs have been NVIS/IVIS (NATS) registered.
The security indic ator i s lo cated on the in strum ent panel. T he in di cato r blin ks wh en th e im mobi lizer sys tem i s
functioning.
Therefore, NVIS/IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

● When NVIS/IVIS (NATS) detects trouble, the security i ndicator lamp lights up while ignition switch is in

"ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.

● When servicin g NVIS/IVIS (NATS) (trouble diag noses, syst em initializatio n and addition al registration of

other NVIS/IVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II NVIS/IVIS (NATS)
software is necessary.
Regarding the procedures of NVI S/IVIS (NATS) initialization and NVIS/I VIS (NATS) ignition key ID re gis­tration, refer to CONSULT-II operation manual, NVIS/IVIS (NATS).

Therefore, CONSULT-II NVIS/IVIS (NAT S) software (pro gram ca rd and operatio n manual) m ust be kept
strictly confidential to maintain the integrity of the anti-theft function.

● When servicin g NVIS/IVIS (NATS) (trouble diag noses, syst em initializatio n and addition al registration of

other NVIS/IVIS (NATS) ignition key IDs), it may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A maximum of four or five key IDs can be regis­tered into NVIS/IVIS (NATS).

● When failing to start the engine first time using the key of NVIS/IVIS (NATS), start as follows.

1. Leave the ignition key in "ON" position for approximately 5 seconds.

2. Turn ignition key to "OFF" or "LOCK" position and wai t approximately 5 seconds.

3. Repeat step 1 and 2 again.

4. Restart the engine while keeping the key separate from any others on key-chain.

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 belo w using a “T” pin. For the b est contact grasp the “T” pin using an alligat or
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 abov e each fe male te rminal. Pro be each

terminal with the “T” pin through the no tch.
Do not insert any ob ject other th an the same type male termin al
into female terminal.

How to Check Enlarged Contact Spring of Terminal

An enlarged contact spring of a terminal may create intermittent signals in the circuit.
If the intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged con­tact spring of female terminal.

1. Assemble a male terminal and approx. 10 cm (3.9 in) of wi re.

Use a male terminal which matches the female terminal.

2. Disconnect the suspected faulty connector and hold it terminal
side up.

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.

RUBBER SEAL INSPECTION

● Most waterproof connectors are provided with a rubber seal

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

● The rubber seal may come off when connectors are discon-

nected. Whenev er connectors are reco nnected, make sure the
rubber seal is properly installed on either side of male or female
connector.

Introduction

Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The fol­lowing 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:

● V ehicle vibration

● Heat sensitive

Vehicle Vibration

The problem may occu r or be com e wors e wh ile dr iving on a roug h road or whe n eng ine i s vibrat in g (idl e with
A/C on). In such a case , you w ill wan t to ch eck f or a vib rati on rel ated con ditio n. Re fer to th e foll owing i llu stra­tion.

CONNECTORS & HARNESS

shake each connect or and harness while monit oring the system for the inciden t you are trying to duplicate.
This test may indicate a loose or poor electrical connection.

HINT

Connectors can be exposed to moi sture. It is possibl e to get a thin film of corrosion on the co nnector termi­nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter­mittently, perhaps the problem is ca used by corrosi on. It is a good i dea to disco nnect, inspec t and clean the
terminals on related connectors in the syste m .

SENSORS & RELAYS

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 full y se ate d.

● Wiring harness not long enough and is being st ressed due to engine vibrati ons or rocking.

● Wires laying across brackets or moving components.

● Loose, dirty or corroded ground wires.

● Wires routed too clos e to ho t components.

To inspect components under the ho od , st a r t by ve r ifyi n g t he i nt e gri t y of gr oun d con ne cti on s. (Re fe r t o Grou nd
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shak ing the wiring or comp onents as previously explained. Using th e wiring diagrams inspe ct 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.

GI-27

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

UNDER SEATING AREAS

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

Heat Sensitive

The customer's concern may occur during h ot weather or after car
has sat for a short time. In such cases you will want to check for a
heat sensitiv e condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat compo nents above 60°C (140°F). If incident occurs
while heating th e unit, either repla ce o r p rop erly insulate the c om p o­nent.

SGI842

Freezing

The customer may indicate the incident goes away after the car
warms up (wint e r tim e) . T he c au se co ul d be r el a ted to wa te r fr ee zi ng
somewhere in the wiring/electrical system.
There are two me thods to check for this. The first is to arra nge for
the owner to leave his car overnight. Make sure 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 m ethod is to put the sus pect component int o a freezer
long enough for any water to freeze. Reinstall the part into the car
and check for the re occurrence of the inci dent. If it o ccurs, repair or
replace the compone nt .

SGI843

Water Intrusion

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

Do not spray water directly on any electrical components.

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.

make a proper diagno sis.

CIRCUIT INSPECTION
Introduction

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 opera tion. Then you will be able to use the approp riate equipm ent and follow
the correct test procedure.
You may have to simula te ve hicl e vib ration s whil e test in g elec trical c ompo nents. Ge ntl y shak e the w irin g har­ness or electrical component to do this.

OPEN

SHORT

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

There are two types of shorts.

● SHORT CIRCUIT

● SHORT TO GROUND When a circuit contacts a ground source and gr ounds the circuit.

When a circuit contacts another circuit and causes the norm al resistanc e to
change.

NOTE:

Refer to “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.

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). Make sure 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 ba tte ry ne gative 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 ot her probe to the fuse b lock (power) side of SW1. Little or no resis tance will indicate th at

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 prob es be tw ee n SW 1 an d th e re la y. Little or no resistance wil l ind ic at e th at p ort ion of th e c ir-

cuit has good conti nuity. If there were an open in the circuit, the DMM would in dicate an over limi t or infi­nite resist ance condition. (point B)

● Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of

the circuit ha s g oo d co nt inu it y. If there were an op en in the ci r cu it, th e DM M wo ul d i n dica te an ov er l i mit o r
infinite resi stance condition. (point C)

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

VOLTAGE CHECK METHOD

To help in understand ing the diagnosis of open circuits please ref er to the previous schematic.
In any powered circu it, an open can b e fou nd by method ical ly ch ecki ng the syste m for t he p res ence of volt a ge.
This is done by switching the DMM to the voltage function.

● Connect o ne 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.

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 disconn ect 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 rela y contacts with jumper wire. Put probes at the load si de of fuse terminal and

a known good ground. Then, check for continuity.
continuity; short is between relay and solenoid (po int C).
no continuity; check solenoid, retrace steps.

VOLTAGE CHECK METHOD

● Remove the bl own fus e and d is con ne ct al l loa ds (i. e. SW 1 ope n, rel ay d is con nect e d an d sole no id di scon-

nected) powered through the fuse.

● Turn the ignition key to the O N or START position. Verify battery voltage at the ba ttery + s ide of the fuse

terminal (on e l ead on th e b at ter y + term in al side of th e fus e b lo ck a nd on e lead on a kn own goo d g rou nd ).

● With SW1 open and the DMM leads across both fuse terminals, check for voltage.

voltage; short is between fuse block and SW1 (point A).

GI-30

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

● 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 unwant ed resistanc e. This unwanted resistance can change the way a circuit works.
Electronical ly cont rol l ed ci rcui t s a r e ve ry se ns it ive to prop er gr ou ndin g. A lo ose or co r rod ed gro un d ca n d rast i­cally affect an elec tronically controlled circui t. A poor or corroded ground c an easily affect the circuit. Eve n
when the groun d connection looks clean, ther e can be a thin film of rust on the surface.
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 interferi ng with the ground circuit.

● If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the

wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.

Voltage Drop Tests

Voltage drop tests are often used to find co mponents or circuits whic h have excessiv e 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 connec tions or splices.

I

J

K

L

M

GI-31

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

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

MEASURING VOLTAGE DROP — ACCUMULATED METHOD

● Connect the DMM ac ross the co nnector or part of the circ uit you wa nt to check. The posit ive lead of t he

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.

Note in the illustration that there is an excessive 4 .1 volt drop between the battery and the bu lb.

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 corros ion.
The step by step v oltage drop test can identify a component or wire with too much resistance.
