DIAGNOSIS SYSTEM (AV CONTROL UNIT)

Speaker Test

Select “SPEAKER DIAGNOSIS” to display the Speaker Diagnosis
screen. Press “START and NEXT” to generate a test tone in a
speaker. Press “Start” to generate a test tone in the next speaker.
Press “End” to stop the test tones.
NOTE:
The frequency of test tone emitted from each speaker is as follows.

Climate Control

Refer to “HEATER & AIR CONDITIONING CONTROL SYSTEM” for details.

Navigation

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.

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 SW 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-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.
