TROUBLE DIAGNOSIS
NOTE:
Follow the procedures in numerical order when repairing malfunctioning parts. Confirm whether malfunction is
eliminated using air bag warning lamp or CONSULT-II each time repair is finished. If malfunction is still
observed, proceed to the next step. When malfunction is eliminated, further repair work is not required.
DIAGNOSTIC PROCEDURE 3
Final Check of SRS Using CONSULT-II—Diagnosis Mode
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
in self-diagnosis depending on control unit which carry out CAN communication.
1. After repairing SRS, connect both battery cables.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “AIR BAG”.
If "AIR BAG" is not indicated, refer toGI-50, "

6. Touch “SELF-DIAG [CURRENT]”.
7. If no malfunction is detected on “SELF-DIAG [CURRENT]”,
repair of SRS is completed. Go to step 8.
If any malfunction is detected on “SELF-DIAG [CURRENT]”, the
malfunctioning part is not repaired completely or another mal-
functioning part is detected. Go toSRS-20, "
DIAGNOSTIC
PROCEDURE 2", and repair malfunctioning part completely.
8. Touch “ERASE”.
NOTE:
Touch “ERASE” to clear the memory of the malfunction
(“SELF-DIAG [PAST]”).
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.
9. Touch “BACK” key of CONSULT-II to “SELECT DIAG MODE”
screen. Touch “SELF-DIAG [PAST]”.
10. Check that no malfunction is detected on “SELF-DIAG [PAST]”.
11. Touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears in order to return to User mode from Diagnosis mode.
12. Turn ignition switch OFF then turn off and disconnect CON-
SULT-II. GotoSRS-18, "

DIAGNOSTIC PROCEDURE 7
1.CHECK CONDITION OF AIR BAG MODULES
Inspect for any deployed air bag modules or seat belt pre-tensioners.
Are any air bag modules or seat belt pre-tensioners deployed?
Yes >> Refer toSRS-56, "COLLISION DIAGNOSIS".
No >> GO TO 2.
2.CHECK THE AIR BAG FUSE
Check 10A fuse [No. 13, located in the fuse block (J/B)].
Refer toPG-4, "
POWER SUPPLY ROUTING CIRCUIT".
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.

Replace 10A fuse [No. 13, located in the fuse block (J/B)] and turn ignition switch ON.
Does the fuse blow again?
Yes >> Repair or replace main harness.
No >> Inspection End.
4.CHECK AIR BAG DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and CONSULT-II CONVERTER and touch
“START”.
Is
“AIR BAG”displayed on CONSULT-II?
Yes >>GOTO5.
No >> Visually inspect the air bag diagnosis sensor unit har-
ness connections. If the connections are OK, replace
the air bag diagnosis sensor unit. Refer toSRS-48,
"Removal and Installation".
5.CHECK HARNESS CONNECTION
Check for loose connections between the combination meter and the air bag diagnosis sensor unit.
OK or NG
OK >> Replace air bag diagnosis sensor unit. Refer toSRS-48, "Removal and Installation".
