Error History
The self-diagnosis results are judged depending on whether any
error occurs from when "Self-diagnosis" isselected until the self-
diagnosis results are displayed.
However, the diagnosis results are judged normal if an error has
occurred before the ignition SW is turned ON and then no error has
occurred until the self-diagnosis start. Check the "Error History" to
detect any error that may have occurred before the self-diagnosis
start because of this situation.
Count up method A
• The counter resets to 0 if an error occurs when IGN switch is
turned ON. The counter increases by 1 if the condition is normal at
a next IGN ON cycle.
