SELF-DIAG RESULTS
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”.
If DTC [U1000], [U1300] are detected, “0” is displayed at TIME.
If it is normal the next time ignition switch is ON of next time, add
1 to the TIME.
Display Item of Self-Diagnostic Results
Self-diagnostic results may be displayed simultaneously according to the cause. If some error items are dis-
played simultaneously, the detection of the cause can be performed by the combination of display items
