HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-IINJRS0043S04From User Mode to Diagnosis ModeNJRS0043S0401When a malfunction is detected, activate the Diagnosis mode by turning theignition switch as follows:
1) Turn ignition switch “ON”.
2) After “AIR BAG” warning lamp lights for 7 seconds, turn ignition switch “OFF” within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch “ON”.
SRS will not enter Diagnosis mode if no malfunction is detected.

HOW TO ERASE SELF-DIAGNOSIS RESULTS=NJRS0043S05With CONSULT-IINJRS0043S0501“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 detectedon “SELF-DIAG [CURRENT]”.
“SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by pushing “BACK” key of CONSULT-II and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is not erased, the User mode shows the sys-
tem malfunction by the operation of the warning lamp even if the malfunction is repaired completely.
SRS701
“TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Without CONSULT-IINJRS0043S0502After a malfunction is repaired, switch the ignition “OFF” for at least onesecond, then back “ON”. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.

If no malfunction is detected on “SELF-DIAG [CURRENT]” but mal-
function is indicated by the “AIR BAG” warning lamp, go to DIAG-
NOSTIC PROCEDURE 4, page RS-56, to diagnose the following
situations:
Self-diagnostic result “SELF-DIAG [PAST]” (previously stored
in the memory) might not be erased after repair.
The SRS system malfunctions intermittently.
8. Touch “PRINT”.
9. Compare diagnostic codes to “CONSULT-II Diagnostic Code
Chart”, RS-51.
10. Touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears in order to return to User mode from Diagnosis mode.
11. Turn ignition switch “OFF”, then turn off and disconnect
CONSULT-II, and disconnect both battery cables.
12. Repair the system as outlined by the “Repair order” in “CON-
SULT-II Diagnostic Code Chart”, that corresponds to the self-
diagnostic result. For replacement procedure of component
parts, refer to RS-26.
13. After repairing the system, go to DIAGNOSTIC PROCEDURE
3, page RS-54 for final checking.
