PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AIS004L9
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 and SB section of this Service Man-
ual.
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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

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.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectAIS00583
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″ LOCK ″ position.

Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for WorkAIS004LA

After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check
their operation.

Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

PRECAUTIONS FOR DIAGNOSIS

Before performing diagnosis, always read precautions. Refer to BRC-12, "How to Proceed with Diagno-
sis" .

If ABS actuator and electric unit (control unit), steering angle sensor, steering system parts or suspension
system parts have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of
steering angle sensor before driving. Refer to BRC-6, "
Adjustment of Steering Angle Sensor Neutral Posi-
tion" .

After diagnosis is finished, be sure to erase memory. Refer to BRC-27, "SELF-DIAGNOSIS" .

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.

For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.

If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.

To use CONSULT-II to perform self-diagnosis of ABS actuator and electric unit (control unit), active tests,
or work support, first stop work, then connect CONSULT-II and select “ABS”.

While self-diagnostic results of CONSULT-II shows malfunction, if CONSULT-II active test is performed,
an engine system error may be indicated. In this case, start engine to resume the normal screen.

VDC/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:
Symptom Symptom description Result
Motor operation noise This is noise of motor inside ABS actuator and electric unit (control unit).
Slight noise may occur during VDC, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), motor and
valves operating noise may be heard. It happens only once after IGN
(ignition) is ON. This is a normal status of the system operation check.
System operation check
noise When engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check. Normal
VDC/TCS operation
(SLIP indicator lamp blink-
ing) TCS may activate momentarily if wheel speed changes when driving
over location where friction coefficient varies, when up/downshifting, or
when fully depressing accelerator pedal.
Normal
Cancel the VDC/TCS
function for the
inspection on a chas-
sis dynamometer.
For inspection of speedometer or other instruments, press
VDC OFF SW to turn VDC/TCS function off.
When accelerator pedal is depressed on a chassis dynamometer (fixed
front-wheel type), vehicle speed will not increase. This is not normal. It is
result of TCS being activated by stationary front wheels. Warning lamp
may also illuminate to indicate “sensor system error”. This is also nor-
mal, and is the result of the stationary front wheels being detected. To be
certain, restart engine, and drive vehicle at 30 km/h (19 MPH) or more.
Make sure warning lamp does not illuminate.
ABS operation (Longer stop-
ping distance) On roads with low friction coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. There-
fore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low. Normal
Insufficient feeling of accel-
eration Depending on road conditions, driver may feel that feeling of accelera-
tion is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation. Normal

DTC C1145, C1146, C1113
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause the G sensor circuit
indicate a malfunction. However, this is not a malfunction, if normal operation can be resumed after
restarting engine.
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
CAUTION:
When on a turntable, such as at a parking structure entrance, or when on a moving object with engine
running, VDC OFF indicator lamp might turn on and self-diagnosis using CONSULT-II the yaw rate sen-
sor system might be displayed, but in this case there is no malfunction in yaw rate sensor circuit. As
soon as vehicle leaves turntable or moving object, restart engine to return the system to normal.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK CONNECTOR
1. Disconnect G sensor connector and ABS actuator and electric unit (control unit) connector and check ter- minals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace
terminal.
2. Reconnect connectors and perform a ABS actuator and electric unit (control unit) self-diagnosis again.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
