OPERATION PROCEDURE
1. Start engine.
2. Turn the audio OFF.
3. While pressing the “SETTING” switch, turn volume dial to the left
or right by at least 40 clicks. (When diagnosis function is acti-
vated, a short beep sounds.)
Press the “BACK” switch and the initial system screen will be
shown.
4. The system diagnostic menu is displayed, and then the items of
“Self Diagnosis” and “Confirmation/Adjustment” can be selected.

DIAGNOSIS SYSTEM
Self Diagnosis Mode
EKS00Q6J
1. Start the diagnosis function, and then select “Self Diagnosis”.
–Self-diagnosis screen is displayed. The system enters in the self-diagnosis mode.
–The bar graph visible on the center of screen indicates the
progress of self-diagnosis.
2. Diagnostic results are displayed when the self-diagnosis is com-
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.
–When selecting the screen switch on self-diagnosis screen, the
comment of self-diagnosis results is displayed.

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.
