plete. Each unit name and connection lines between each unit
will be colored according to the diagnostic results, as follows.
* : Only control unit (NAVI control unit) is displayed in red.
NOTE:
lSwitch: AV switch
lControl unit: NAVI control unit
lAmplifier is built in Audio unit.
–If multiple malfunctions occur at the same time for a single unit, the screen switch colors are determined
according to the following order of priority: red > yellow > gray.

ERROR DETECTION RANGE OF SELF-DIAGNOSIS MODE
lSelf-diagnosis mode can perform the connection condition diagnosis of communication circuit between
NAVI control unit and each unit and the NAVI control unit diagnosis.
lSince the start condition of diagnosis function is switch operation, if the malfunction is detected in the
communication circuit between NAVI control unit and AV switch, on board diagnosis function cannot be
started.
DIAGNOSIS RESULTS
Check the applicable display at the DTC quick reference table, and then repair the malfunctioning parts.
