- The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
Detection range of self-diagnosis mode
 The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between NAVI control unit and each unit and the internal operation of the NAVI control unit.
 Because the start condition of diagnosis function is a switch operation, the on board diagnosis function can-
not be started up if any malfunction is detected in a switch.
Self-diagnosis results
Check the applicable display at the following table, and then repair the malfunctioning parts.
