On Board Diagnosis Item

WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

The on board diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and a confirmation/adjustment mode for operating manually.
Self-diagnosis mode performs the diagnosis at the AV control unit, connections between each unit that composes the system, and connections between AV control unit and GPS antenna. It displays the results on the display.
The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and set values, as well as to monitor the system error records and system communication status. The check, modify or adjust actions generally require human intervention and judgment (the system cannot judge automatically).
