dial clockwise or counterclockwise for 40 clicks or more. (When
the self-diagnosis mode is started, a short beep will be heard.)
 Shifting from current screen to previous screen is performed
by pressing “BACK” button.
4. The trouble diagnosis initial screen is displayed, and then the
items of “Self Diagnosis” and “Confirmation/Adjustment” can be
selected.
SELF-DIAGNOSIS MODE
1. Start the self-diagnosis function and select “Self Diagnosis”.
- Self-diagnosis subdivision screen is displayed, and the self-diagnosis mode starts.
- The bar graph visible on the center of the self-diagnosis subdivision screen indicates progress of the trou-
ble diagnosis.
Confirmation/
AdjustmentDisplay DiagnosisThe following check functions are available: color tone check by color
bar display, light and shade check by grey scale display and touch panel
calibration response check.
Vehicle SignalsDiagnosis of signals can be performed for vehicle speed, parking brake,
lights, ignition switch, and reverse.
Speaker Test The connection of a speaker can be confirmed by test tone.

DIAGNOSIS SYSTEM (AV CONTROL UNIT)
2. Diagnosis results are displayed after the self-diagnosis is com-
pleted. The unit names and the connection lines are color-coded
according to the diagnostic results.
NOTE:
 Only the control unit (AV control unit) is displayed in red.
 Replace AV control unit if “Self-Diagnosis did not run because of a control unit malfunction” is indicated.
The symptom is AV control unit internal error. Refer to AV-378, "
Removal and Installation".
- If multiple errors occur at the same time for a single unit, the screen switch colors are determined accord-
ing to the following order of priority: red > yellow > gray.
- The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
SELF-DIAGNOSIS RESULTS
 The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between AV control unit and each unit and the internal operation of the AV 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 the communication circuit between AV control unit and
multifunction switch.
 Check the applicable display in the following table, and then repair the malfunctioning parts.

Error History
The self-diagnosis results are judged depending on whether any error occurs from when “Self-diagnosis” is
selected until the self-diagnosis results are displayed.
However, the diagnosis results are judged normal if an error has occurred before the ignition switch is turned
ON and then no error has occurred until the self-diagnosis start. Check the “Error Record” to detect any error
that may have occurred before the self-diagnosis start because of this situation.
The error record displays the time and place of the most recent occurrence of that error. However, take note of
the following points.
 Place of the error occurrence is represented by the position of the current location mark at the time an error
occurred. If current location mark has deviated from the correct position, then the place of the error occur-
rence cannot be located correctly.
 The frequency of occurrence is displayed in a count up manner. The actual count up method differs depend-
ing on the error item.
Count up method A
 The counter resets to 0 if an error occurs when IGN switch is turned ON. The counter increases by 1 if the
condition is normal at a next IGN ON cycle.
 The counter upper limit is 39. Any counts exceeding 39 are ignored.“ The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT-III.
Count up method B
 The counter increases by 1 if an error occurs when IGN switch is ON. The counter will not decrease even if
the condition is normal at the next IGN ON cycle.
 The counter upper limit is 50. Any counts exceeding 50 are ignored. “ The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT-III.Squawker : 3 kHz
