HOW TO ERASE SELF-DIAGNOSIS RESULTS
l“SELF-DIAG [CURRENT]”
A current self-diagnosis result is displayed on the CONSULT-II
screen in real time.
After the malfunction is repaired completely, no malfunction is
detected on “SELF-DIAG [CURRENT]”.
l“SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by
touching “BACK” key of CONSULT-II and select “SELF-DIAG
[PAST]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-
DIAG [PAST]” mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is
not erased, the User mode will continue to show the system
malfunction by the operation of the warning lamp even if
the malfunction is repaired completely.
l“TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-II)EHS001XM
lThe reading of these results is accomplished using one of two modes — “User mode” and “Diagnosis
mode”.
lAfter a malfunction is repaired, turn the ignition switch OFF for at least one second, then back ON. Diag-
nosis mode returns to the User mode. At that time, the self-diagnostic result is cleared.

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".

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.
