Self Diagnosis Result

WARNING: This page is about a different car, the 2008 Infiniti M45 and 2008 Infiniti M35. However, it is still accessible from the selected car via links, so may be relevant.

In CONSULT-III self-diagnosis, self-diagnosis results and error history are displayed collectively.
The current malfunction indicates "CRNT". The past malfunction indicates "PAST".
The timing is displayed as "0" if any of the error codes [U1000], [U1010], [U1300] and [U1310] is detected.
The counter increases by 1 if the condition is normal at the next ignition switch ON cycle.
