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, "
CONSULT-II Data
Link Connector (DLC) Circuit".

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.

DIAGNOSTIC PROCEDURE 4 (CONTINUED FROM DIAGNOSTIC PROCEDURE 2)
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]” (previously stored in the memory) might not be erased
after repair. Go toSRS-24, "
DIAGNOSTIC PROCEDURE 3".
No >> Go toSRS-20, "
DIAGNOSTIC PROCEDURE 2".
DIAGNOSTIC PROCEDURE 5
Check SRS Intermittent Malfunction 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. Turn ignition switch OFF.
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”.
