DIAGNOSIS SYSTEM (AV CONTROL UNIT)

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

On-board self-diagnosis is not supported. Only CONSULT-III is supported.
Refer to 

HAC-39, "CONSULT-III Function"

 [without 7 inch display].

Refer to 

HAC-161, "CONSULT-III Function"

 [with 7 inch display].

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.
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 the 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.

Error Item
Some error items may be displayed simultaneously according to the cause. If some error items are displayed
simultaneously, the detection of the cause can be performed by the combination of display items
