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 thecondition is normal at
a next IGN 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-III.

Count up method B
• The counter increases by 1 if an error occurs when IGN switch is ON. The counter will not decrease even

ifthe condition is normal at the next IGN 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-III.

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
