DIAGNOSIS SYSTEM (AV CONTROL UNIT)

Description

INFOID:0000000009163339

• The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit

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

• Perform a CONSULT 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 Function

INFOID:0000000009163340

MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION

The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be
checked.

Self-diagnosis Mode

• Press both the preset switches “1” and “6” simultaneously within 10

seconds after turning the ignition switch from OFF to ACC and hold
them for 3 seconds or more. Then release the switches. The
buzzer sounds, all indicators of the centralized and preset switches
illuminate, and the self-diagnosis mode starts.

• The continuity of each switch at the ON position can be checked

by pressing the switch. The buzzer sounds if the switch is normal.

Finishing Self-diagnosis Mode

Self-diagnosis mode is canceled when turning the ignition switch OFF.

ON BOARD DIAGNOSIS ITEM

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 AV control unit, connections between system compo-

nents as well as connections between AV 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 checking,
modifying or adjusting generally require human intervention and judgment (the system cannot make judg-
ment automatically).

The trouble diagnosis initial screen is displayed, and then the
items of “Self Diagnosis” and “Confirmation/Adjustment” can be
selected.

SELF-DIAGNOSIS MODE

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.

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 con-

trol unit internal error. Refer to

AV-168, "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 > gray.

The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.

SELF-DIAGNOSIS RESULTS

Check the applicable display at the following table, and then repair the malfunctioning parts.

STEERING ANGLE ADJUSTMENT
The steering angle output value detected with the gyroscope is
adjusted.

SPEED CALIBRATION
During normal driving, distance error caused by tire wear and tire
pressure change is automatically adjusted for by the automatic dis-
tance correction function. This function, on the other hand, is for
immediate adjustment, in cases such as driving with tire chain fitted
on tires.

XM SAT SUBSCRIPTION STATUS
The XM NavTraffic subscription status can be checked.

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.

• If there is a malfunction with the GPS antenna circuit board in the AV control unit, the correct date and time

of occurrence may not be able to be displayed.

• 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.

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.
