HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-II
From User Mode to Diagnosis Mode
After selecting ªAIR BAGº on the ªSELECT SYSTEMº screen, User mode automatically changes to Diagno-
sis mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch ªBACKº key of CONSULT-II until ªSELECT SYSTEMº
appears, Diagnosis mode automatically changes to User mode.
HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-II
From User Mode to Diagnosis Mode
When a malfunction is detected, activate the Diagnosis mode by turning the ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.
SRS will not enter Diagnosis mode if no malfunction is detected.
From Diagnosis Mode to User Mode
After a malfunction is repaired, switch the ignition ªOFFº for at least one second, then back ªONº. Diagnosis
mode is returned to User mode.
When a malfunction is detected, switch from Diagnosis mode to User mode by turning the ignition switch as
follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
IªSELF-DIAG [CURRENT]º
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 ªSELF-DIAG [CURRENT]º.
IªSELF-DIAG [PAST]º
Return to the ªSELF-DIAG [CURRENT]º CONSULT-II screen by pushing ªBACKº key of CONSULT-II and
select ªSELF-DIAG [CURRENT]º in SELECT DIAG MODE. Touch ªERASEº in ªSELF-DIAG [CURRENT]º
mode.
NOTE:
If the memory of the malfunction in ªSELF-DIAG [PAST]º 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.
IªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, switch the ignition ªOFFº for at least one second, then back ªONº. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.
