< SERVICE INFORMATION >
SERVICE INFORMATION A
PRECAUTION

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT B

PRE-TENSIONER"

INFOID:0000000004779261

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

C

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.

D

Information necessary to service the system safely is included in the SRS and SB section of this Service Man-

ual.

WARNING:

E

· 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

F

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 G

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-

ness connectors.

· When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni- H tion 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 I

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

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
J
INFOID:0000000004750049

NOTE:

· This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYSTEM).

DI

· Remove and install all control units after disconnecting both battery cables with the ignition knob in the

LOCK position.

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

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

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-

anism is adopted on the key cylinder.

M

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.

N

OPERATION PROCEDURE

1. Connect both battery cables.

O

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.

P

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-III.

WKIA5977E

Oil Pressure Warning Lamp The oil pressure warning lamp is controlled by the double meter. When the oil pressure is less than 4.52 psi F

(0.318 kg/cm2), the double meter sends a ground signal to the IPDM E/R. The IPDM E/R then sends a signal

to the combination meter via CAN communication and the oil pressure warning lamp is turned on. When the oil

pressure is greater than 6.5 psi (0.457 kg/cm2) the warning lamp turns off.

G-FORCE GAUGE
The G-force gauge indicates the longitudinal acceleration and deceleration G-forces while driving. The indica- P tion is based on a calculation using the speed input supplied by the combination meter via CAN communication. The gauge does not indicate cornering G-forces.

WARNING CHIME
< SERVICE INFORMATION > · When combination meter receives key warning signal, it sounds warning chime.

WKIA5836E
When Intelligent Key Is Carried With The Driver Refer to BL-72, "System Description".
LIGHT WARNING CHIME
The warning chime sounds, when driver's door is opened (door switch ON) with lighting switch ON and the ignition switch is in any position other than ON or START. NOTE: BCM detected lighting switch in the 1st or 2nd position, refer to LT-59, "Combination Switch Reading Function". · BCM detects headlamps are illuminated, and sends light warning signal to combination meter with CAN
communication lines. · When the combination meter receives light warning signal, it sounds warning chime.

WKIA5465E
SEAT BELT WARNING CHIME
With the ignition switch turned ON and driver's seat belt unfastened, the seat belt warning chime will sound for approximately 6 seconds. · The combination meter reads an ON/OFF signal from the seat belt buckle switch LH, and transmits the seat
belt buckle switch signal to the BCM with CAN communication. · The BCM detects the ignition switch turned ON and seat belt buckle switch LH ON. And then, transmits the
buzzer output signal (seat belt warning chime) to the combination meter with CAN communication. · When the combination meter receives the buzzer output signal (seat belt warning chime), it sounds the
buzzer.

LKIA0878E
PARKING BRAKE WARNING CHIME
