TROUBLE DIAGNOSIS
NOTE:
Follow the procedures in numerical order when performing repairs. Confirm whether the repair has been suc-
cessful using air bag warning lamp or CONSULT-III after each repair. If malfunction is still observed, proceed
to the next step. When malfunction has been elimi nated, further repair work is not required.
DIAGNOSTIC PROCEDURE 3
Final Check of SRS Using CONSULT-III—Diagnosis Mode
1. If no DTC is detected on “SELF-DIAG [CURRENT]”, repair of SRS is completed. Go to step 2.
If any DTC is detected on “SELF-DIAG [CURRENT]” , the malfunctioning part has not been repaired com-
pletely or another malfunctioning part is being detected. Go to "DIAGNOSTIC PROCEDURE 2".
2. Touch “ERASE”. NOTE:
Touch “ERASE” to clear the memory of the malfunction (“SELF-DIAG [PAST]”).
If the memory of the malfunction in “SELF-DIAG [P AST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.
3. Touch “BACK” key of CONSULT-III to “SELECT DIAG MODE” screen. Touch “SELF-DIAG [PAST]”.
4. Check that no malfunction is detected on “SELF-DIAG [PAST]”.
5. Touch “BACK” key of CONSULT-III until “SELECT SY STEM” appears in order to return to User mode from
Diagnosis mode.
6. Turn ignition switch OFF then turn off and disconnect CONSULT-III.
7. Go to SRS-19, "
SRS Operation Check".
DIAGNOSTIC PROCEDURE 4
Check SRS Repair History
1.CONSIDER POSSIBILITY THAT SELF-DIAGNOSTIC RESULT WAS NOT ERASED AFTER REPAIR
Check repair history of the SRS.
Have any previous repairs been made to the SRS?
Yes >> Self-diagnostic result “SELF-DIAG [PAST]” (pre viously stored in the memory) might not be erased
after repair. Go to "DIAGNOSTIC PROCEDURE 3".
No >> Go to "DIAGNOSTIC PROCEDURE 2".
DIAGNOSTIC PROCEDURE 5
Check SRS Intermittent Malfuncti on Using CONSULT-III—Diagnosis Mode
1. If diagnostic codes are displayed on “SELF-DIAG [PAST]”, go to step 4.
If no malfunction is detected on “SELF-DIAG [PAS T]”, touch “BACK” and go back to “SELECT DIAG
MODE”.
BELT TENSION SENS
[UNIT FAIL]
[B1019] Belt tension sensor is malfunctioning.
1. Visually check the wiring harness
connection.
2. Replace the harness if it has visi- ble damage.
3. Replace the RH front seat belt as- sembly.
4. Replace the RH front seat cush-
ion assembly. Do not disassem-
ble the seat cushion assembly.
5. Replace the related harness.
FRONTAL COLLISION DETECTION[B1209] Driver and front passenger air bag modules are deployed. Refer to
SRS-48, "
For Frontal Colli-
sion".
SIDE COLLISION DETECTION
[B1210] Side or curtain air bag modules are deployed.
Refer to SRS-50, "
For Side and Roll-
over Collision".

Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005931269
The Supplemental Restraint System such as “A IR 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 w hether 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 inopera tive, 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 unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005931270
NOTE:
• This Procedure is applied only to models with In telligent 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-III 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 pow er 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.

TIRE PRESSURE MONITORING SYSTEM
A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.
REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver is shown with the glove box
removed. The remote keyless entry receiver receives the air pres-
sure signal transmitted by the transmitter in each wheel.
COMBINATION METER
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.
TIRE PRESSURE WARNING CHECK CONNECTOR
The tire pressure warning check connector can be grounded in order to initiate self-diagnosis without a CON-
SULT-III. Refer to WT-17, "
Self-Diagnosis (Without CONSULT-III)". The tire pressure warning check connector
is located behind the lower portion of the instrument panel LH. Refer to PG-39, "
Harness Layout".
