7. Diagnostic code is displayed on “SELF-DIAG [CURRENT]”.
If no malfunction is detected on “SELF-DIAG [CURRENT]” even
though malfunction is detected in “SRS Operation Check”, check the
battery voltage. If the battery voltage is less than 9V, charge or
replace the battery. Then go to SRS-23, "
DIAGNOSTIC PROCE-
DURE 3" . If the battery voltage is OK, go to SRS-25, "DIAGNOSTIC
PROCEDURE 4 (CONTINUED FROM DIAGNOSTIC PROCEDURE
2)" to diagnose the following cases:
Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in
the memory) might not be erased after repair.
The SRS system malfunctions intermittently.

Trouble Diagnosis: “AIR BAG” Warning Lamp Does Not Turn OFFAHS000HU
DIAGNOSTIC PROCEDURE 7
1. CHECK THE DEPLOYMENT OF AIR BAG MODULE
Is air bag module deployed?
YES or NO
YES >> Refer to SRS-56, "COLLISION DIAGNOSIS" .
NO >> GO TO 2.
2. CHECK THE AIR BAG FUSE
Check 10A fuse [No. 13, located in fuse block (J/B)].
Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. CHECK AIR BAG FUSE AGAIN
Replace “AIR BAG” fuse and turn ignition switch ON.
Does the
“AIR BAG” fuse blow again?
YES >> Repair main harness.
NO >>INSPECTION END
4. CHECK DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and touch “START”.
Is “AIR BAG” displayed on CONSULT-II?
YES or NO
YES >> GO TO 5.
NO >> Visually check the wiring harness connection of diagno-
sis sensor unit. If the harness connection check result is
OK, replace diagnosis sensor unit.
5. CHECK HARNESS CONNECTION
Is harness connection between warning lamp and diagnosis sensor unit OK?
OK or NG
OK >> Replace diagnosis sensor unit.
NG >> Connect “AIR BAG” warning lamp and diagnosis sensor unit connector properly. If “AIR BAG”
warning lamp still does not go off, replace harness.

ASSEMBLY" .
2. Remove display control unit, if navigation system is equipped.
3. Remove tire pressure warning control unit, if tire pressure warning control system is equipped.
4. Disconnect front passenger air bag module connector.
5. Remove the front passenger air bag module fixing nuts and bolt,
then remove front passenger air bag module.
CAUTION:
Always place front passenger air bag module with caution
label side facing upward.

CONSULT-II Function (ALL MODE AWD/4WD)ADS000S5
FUNCTION
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II SETTING PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
For details, refer to the separate “CONSULT-II Operations Man-
ual”.
1. Turn ignition switch “OFF”.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector on vehicle.
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “ALL MODE AWD/4WD”.
If “ALL MODE AWD/4WD” is not indicated, go to GI-40, "
CON-
SULT-II Data Link Connector (DLC) Circuit" .
6. Perform each diagnostic test mode according to each service
procedure.
SELF-DIAG RESULT MODE
Operation Procedure
1. Perform “CONSULT-II SETTING PROCEDURE”. Refer to TF-21, "CONSULT-II SETTING PROCEDURE"
.

3. Stop vehicle. With engine at idle, touch “SELF-DIAG RESULTS”.
Display shows malfunction experienced since the last erasing
operation.
NOTE:
The details for “TIME” are as follow:
–“0”: Error currently detected with AWD control unit.
–Except for “0”: Error detected in the past and memorized
with AWD control unit.
Detects frequency of driving after DTC occurs (frequency
of turning ignition switch “ON/OFF”).
Display Item List
CAUTION:
If “CAN COMM CIRCUIT [U1000]” is displayed with other DTCs, first perform the trouble diagnosis for CAN communica-
tion.
Make sure that ABS warning lamp turns OFF by driving for a minute at vehicle speed of 30 km/h (19 MPH) or more after
turning ignition switch "OFF" if AWD warning lamp turns ON with system malfunction of “ABS SYSTEM [C1203]”. AWD
warning lamp may not turn OFF if it is normal unless ignition switch turns OFF at once and engine restarts after that.
How to Erase Self-diagnostic Results
1. Perform applicably inspection of malfunctioning item and then repair or replace.
2. Start engine and drive at 30 km/h (19 MPH) or more for approx. 1 minute.
3. Make sure that ABS warning lamp turns OFF.
NOTE:
Make sure that ABS warning lamp turns OFF by driving for a minute at vehicle speed of 30 km/h
(19 MPH) or more after turning ignition switch "OFF" if AWD warning lamp turns ON with system
malfunction of “ABS SYSTEM [C1203]”. AWD warning lamp may not turn OFF if it is normal unless
ignition switch turns OFF at once and engine restarts after that.
4. Turn ignition switch “OFF” to erase memory.
5. Start engine and select “SELF-DIAG RESULTS” mode for “ALL MODE AWD/4WD” with CONSULT-II.
6. Touch “ERASE” on CONSULT-II screen to erase DTC memory.
CAUTION:
If memory cannot be erased, perform applicably diagnosis.
7. Drive at 30 km/h (19 MPH) or more for approx. 1 minute. Be sure AWD warning lamp is OFF.
