Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS004CC
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.
WAR NING :
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 for ICC System ServiceNKS004CD
Do not look straight into the laser beam discharger when adjusting laser beam aiming.
Turn the MAIN switch OFF in conditions similar to driving, such as free rollers or a chassis dynamometer.
Do not use the ICC sensor integrated unit removing from vehicle. Never disassemble and remodel.
Erase DTC when replacing parts of ICC system, then check the operation of ICC system after adjusting
laser beam aiming if necessary.

TROUBLE DIAGNOSIS - GENERAL DESCRIPTION
Revision: 2006 January2006 M35/M45
Self-Diagnostic FunctionNKS004CY
WITH CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-10, "ACTION
TEST" .
2. Stop vehicle, turn ignition switch OFF, then connect CONSULT-II and CONSULT-II CONVERTER to data
link connector.
3. With engine started, touch “START (NISSAN BASED VHCL)”, “ICC”, “SELF-DIAG RESULTS” on CON-
SULT-II screen in this order.
CAUTION:
If “ICC” cannot be shown after several attempts, the ICC sensor integrated unit may have had mal-
function. Repair or replace it. Refer to GI-40, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. “DTC RESULTS” and “TIME” are indicated on “SELF-DIAG RESULTS”. “TIME” is used as a reference
data of diagnosis. It shows when malfunction is detected.
NOTE:
“TIME” shows the following.
0: malfunction is detected at present (from malfunction detection to ignition switch OFF).
CAN communication ([U1000], [U1010])
1 ~ 39: Displays when it is normal at present and finds malfunction in the past. It increases like
0
12...3839 after returning to the normal condition whenever IGN OFFON. If it is over 39, it is
fixed to 39 until the self-diagnostic results are erased. It returns to 0 when malfunction is detected again
in the process.
Other than CAN communication (other than [U1000], [U1010])
1 ~ 49: Displays when it is normal at present and finds malfunction in the past. It increases like
0
12...4849 after returning to the normal condition whenever IGN OFFON. If it is over 49, it is
fixed to 49 until the self-diagnostic results are erased. It returns to 0 when malfunction is detected again
in the process.
If “NO DTC...” is shown, check ICC system warning lamp. If any malfunction is indicated, GO TO step 5.
5. According to ACS-39, "
Diagnostic Trouble Code (DTC) Chart" , perform appropriate check, and repair or
replace malfunctioning part as necessary.
6. Turn ignition switch OFF.
7. Start engine and touch “START (NISSAN BASED VHCL)”, “ICC”, “SELF-DIAG RESULTS” and “ERASE”
on CONSULT-II display in turn to erase the memory.
CAUTION:
If the memory does not erase, go to 5.
8. Perform ICC system running test (drive vehicle with ICC system ON), and make sure that ICC system
warning lamp does not illuminate.
WITHOUT CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-10, "ACTION
TEST" .
2. Stop the vehicle and turn ignition switch OFF.
3. Start engine.
4. From 5 seconds through 15 seconds after start engine, press
RESUME/ACCELERATE switch 5 times, and SET/COAST
switch 5 times.
CAUTION:
Never turn the MAIN switch ON.
When operation above is not completed from 5 seconds
through 15 seconds, start again from above go to 3.
If self-diagnosis mode cannot be started after several
attempts, the ICC sensor integrated unit may have had
malfunction. Repair or replace it. Refer to ACS-36, "
SELF-
DIAGNOSIS BY DOT MATRIX LCD WILL NOT RUN" .PKIB8371E
