ing repairs.

HOW TO ERASE SELF-DIAGNOSIS RESULTS

“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
detected on “SELF-DIAG [CURRENT]”.

“SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by
touching “BACK” key of CONSULT-II and select “SELF-DIAG
[PAST]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-
DIAG [PAST]” mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is
not erased, the User mode will continue to show 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.
Self-Diagnosis Function (Without CONSULT-II)EHS000WF

The reading of these results is accomplished using one of two modes — “User mode” and “Diagnosis
mode”.

After a malfunction is repaired, turn the ignition switch OFF for at least one second, then back ON. Diag-
nosis mode returns to the User mode. At that time, the self-diagnostic result is cleared.
