Error History
The self-diagnosis results are judged depending on whether any error occurs from when “Self-diagnosis” is
selected until the self-diagnosis results are displayed.
However, the diagnosis results are judged normal if an error has occurred before the ignition switch is turned
ON and then no error has occurred until the self-diagnosis start. Check the “Error Record” to detect any error
that may have occurred before the self-diagnosis start because of this situation.
The frequency of occurrence is displayed in a count up manner. The actual count up method differs depending
on the error item.
Count up method A
• The counter resets to 0 if an error occurs when ignition switch is turned ON. The counter increases by 1 if
the condition is normal at a next ignition ON cycle.
• The counter upper limit is 39. Any counts exceeding 39 are ignored.“ The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT.
Count up method B
• The counter increases by 1 if an error occurs when ignition switch is ON. The counter will not decrease even
if the condition is normal at the next ignition ON cycle.
• The counter upper limit is 50. Any counts exceeding 50 are ignored. “ The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT.
