PRECAUTIONS
A
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000003597499
B
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. Information necessary to service the system safely is included in the “SUPPLEMENTAL C
RESTRAINT SYSTEM” and “SEAT BELTS” 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 D
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 E
Module, see the “SUPPLEMENTAL RESTRAINT SYSTEM”.
• 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 har-
F
ness connectors.
Precaution for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000003597500
G
• Do not use electrical test equipment to check SRS circuits unless instructed in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect battery negative terminal. Then wait at least 3
minutes. RS
For approximately 3 minutes after the battery negative terminals removed, it is still possible for the air bag
and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3
minutes have passed.
I
• Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformations or rust before instal-
lation and replace if required.
• The spiral cable must be set to the neutral position since its rotations are limited. Do not attempt to turn J
steering wheel or column, if steering gear was disconnected from the column shaft.
• Handle air bag module carefully. Always put a driver air bag module with the pad side facing upward.
• Conduct self-diagnosis to check entire SRS for proper function after replacing any components. K
• After an air bag deploymented, the front instrument panel assembly should be replaced if damaged.
• Always replace instrument panel pad following front passenger air bag deployment.
Precaution for Battery Service INFOID:0000000003597501 L
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic M
window function will not work with the battery disconnected.

CONSULT-III Function INFOID:0000000003597513 P
DIAGNOSIS MODE FOR CONSULT-III
• “SELF-DIAG [CURRENT]”
A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-III screen in real time. This refers to a malfunctioning part requiring
repairs.
• “SELF-DIAG [PAST]”
RS-9
TROUBLE DIAGNOSIS
< SERVICE INFORMATION >
Diagnosis results previously stored in the memory are displayed on the CONSULT-III screen. The stored
results are not erased until memory erasing is executed.
• “TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-III screen.
• “ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification number.
This number will be displayed on the CONSULT-III screen, as shown. When replacing the diagnosis sensor
unit, refer to the part number for the compatibility. After installation, replacement with a correct unit can be
checked by confirming this classification number on the CONSULT-III screen.
After repair, make sure the discriminated number of diagnosis sensor unit installed to vehicle are same.
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-III
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, then diagnosis mode automatically changes to User mode.
HOW TO ERASE SELF-DIAGNOSIS RESULTS
• “SELF-DIAG [CURRENT]”
A current Self-diagnosis result is displayed on the CONSULT-III screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.
• “SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-III screen by touching “BACK” key of CONSULT-III and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.
• “TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-III) INFOID:0000000003597514
• The reading of these results is accomplished “User mode” and “Diagnosis mode”.
• After a malfunction is repaired, turn ignition switch ON. Diagnosis mode returns to the User mode. At that
time, the self-diagnostic result is cleared.
