To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, Diagnosis mode automatically changes to User mode.
HOW TO ERASE SELF-DIAGNOSIS RESULTS
NOTE:
If the memory in “SELF-DIAG [PAST]” is not erased, User mode will continue to show the system mal-
function by the operation of th e warning lamp even if the malfun ction is repaired completely.
• “SELF-DIAG [CURRENT]” A current self-diagnosis result is displayed on the CO NSULT-III 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-III screen by touching “BACK” key of CONSULT-III and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
