HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
lªSELF-DAIG [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.
lªSELF-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.
lªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, return to User mode from Diagnosis mode by switching the ignition ªOFFº
for at least 1 second, then back ªONº. Diagnosis mode returns to the User mode. At that time, self-diagno-
sis result is cleared.
