DIAGNOSIS SYSTEM (NAVI CONTROL UNIT)

Diagnosis Description

INFOID:0000000001728643

MULTI AV SYSTEM on board diagnosis function

• The NAVI control unit diagnosis function starts up with audio switch operation and the NAVI control unit per-

forms a diagnosis for each unit in the system during the on board diagnosis.

• Perform a CONSULT-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display

anything, the multifunction switch does not function. etc.

On board diagnosis

Description

• The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and

a confirmation/adjustment mode for operating manually.

• The self-diagnosis mode performs diagnoses on the NAVI control unit, connections between system compo-

nents as well as connections between NAVI control unit and GPS antenna. Then it displays the diagnosis
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 make judg-
ment automatically).

• 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.

not be started up if any malfunction is detected in a switch.
