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 error record displays the time and place of the most recent occurrence of that error. However, take note of
the following points.
• Place of the error occurrence is represented by the position of the current location mark at the time an error

occurred. If current location mark has deviated from the correct position, then the place of the error occur-
rence cannot be located correctly.

• The frequency of occurrence is displayed in a count up manner. The actual count up method differs depend-

ing on the error item.

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.

• 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 if

the 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.
