Confirm/Change Bluetooth Passkey
 The passkey of Bluetooth can be confirmed and changed.
 The passkey can be changed by four to eight digits within the num-
ber of 0 to 9.
Confirm/Change Bluetooth Device Name
 The device name of Bluetooth can be confirmed and changed.
 The device name can be changed within the range of twenty digits
of alphabets and codes.
Speaker Test
Select “SPEAKER TEST” 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-159, "
WITH INTELLIGENT AIR CONDITIONER SYSTEM : CONSULT-III Function" for details.
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 frequency of occurrence in error history is displayed in a count up manner. The actual count up method
differs depending on the error item.
