HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT
+``SELF-DIAG [CURRENT]''
A current Self-diagnosis result is displayed on the CONSULT screen in real time. After the malfunction is
repaired completely, no malfunction is detected on ``SELF-DIAG [CURRENT]''.
+``SELF-DIAG [PAST]''
Return to the ``SELF-DIAG [CURRENT]'' CONSULT screen by
pushing ``BACK'' key of CONSULT 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 system malfunction by the
operation of the warning lamp even if the malfunction is
repaired completely.
+``TROUBLE DIAG RECORD''
The memory of ``TROUBLE DIAG RECORD'' cannot be erased.
Without CONSULT
After a malfunction is repaired, return to User mode from Diagnosis mode by switching the ignition ``OFF'' for
at least 1 second, then back ``ON''. At that time, the problem code is cleared.
