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 is set to 40 if an error occurs. 1 is subtracted from the counter if the condition is normal at a next
ignition ON cycle.
• The counter lower limit is 1. The counter can be reset (no error record display) with the Delete log switch.
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.
Error item
Some error items may be displayed simultaneously according to the cause. If some error items are displayed
simultaneously, the detection of the cause can be performed by the combination of display items
