With NAVI
Count Down Type
When the error is detected, set the counter to 40. If the system is normal when turning the ignition switch
ON, the counter decreases by 1.
The lower limit of the counter is 1. It can be reset to 0 by “Delete log” switch or CONSULT-II.
Count Up Type
When the ignition switch is turned ON if the error is detected, the counter increases 1. Even if it is normal
when the ignition switch is turned ON the next time, the counter does not decrease.
The upper limit of the counter is 50. 51 or more is displayed as 50. It can be reset to 0 by “Delete log”
switch or CONSULT-II.
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

The self-diagnosis is started and self-diagnostic results are dis-
played by touching “START” after selecting “SELF-DIAG RESULTS”.
In CONSULT-II self-diagnosis, self-diagnostic results and error
history are displayed collectively.
The current malfunction indicates “CRNT”. The past malfunction
indicates “PAST”.
