HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result is displayed on the CONSULT-II screen in real time. After the malfunc-
tion is repaired completely, no malfunction is detected on ªSELF-DIAG [CURRENT]º.
+ªSELF-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 ªSELECT DIAG MODEº. 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 system malfunction by
the operation of the warning lamp even if the malfunction is
repaired completely.
+ªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, return Diagnosis mode to User mode by switching the ignition ªOFFº for at
least 1 second, then back ªONº. At that time, the self-diagnostic result is cleared.
How to Perform Trouble Diagnoses for Quick
and Accurate Repair
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
INFORMATION FROM CUSTOMER
WHAT ........ Vehicle model
WHEN ....... Date, Frequencies
WHERE ..... Road conditions
HOW .......... Operating conditions, Symptoms
PRELIMINARY CHECK
Check that the following parts are in good order.
+Battery [Refer to EL section (ªBATTERYº) of Service Manual.]
+Fuse [Refer to EL section (ªFuseº, ªPOWER SUPPLY ROUTINGº) of Service Manual.]

6. Turn ignition switch ªONº. ªAIR BAGº warning lamp operates
in User mode. Compare ªAIR BAGº warning lamp operation
to the chart below.
NOTE:
If switching Diagnosis mode to User mode is required while
malfunction is being detected, by turning 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 twice (Perform 3 times in total).
5) Turn ignition switch ªONº.
