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-38, "CONSULT-III Function"

 [without 7 inch display].

Refer to 

HAC-157, "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

DIAGNOSIS SYSTEM (TEL ADAPTER UNIT)

Diagnosis Description

INFOID:0000000003356762

HANDS-FREE PHONE SYSTEM ON BOARD DIAGNOSIS

 During on board diagnosis the diagnosis function of TEL adapter unit starts with the operation of the steering
switch and performs the diagnosis when ignition switch ACC. 

On board diagnosis item

The on board diagnosis has 3 modes: the self-diagnosis mode that performs the trouble diagnosis, the
speaker adaptation data deleting mode and the hands-free phone system initialization mode.

CAUTION:

• Perform the diagnosis with the vehicle stopped.
• Perform STEP2 if necessary.

Self-diagnosis results

Self-diagnosis mode reads out the self-diagnosis results and indicates DTC on the display.
NOTE:
• Error count is read out simultaneously when reading out the DTC name.
• The errors are read out continuously when some errors occur at the same time. The DTC displays are com-

bined and displayed. For example, DTC 01100 is displayed when DTC 01000 and DTC 00100 are indicated
at the same time.

Self-diagnosis results

The details of error count

The error count guides “0” when the error occurs. The next time it counts up “1” if it is normal with the ignition
switch ON. It continues the count up unless the initialization of hands-free phone system is performed.

STEP

MODE

Description

STEP1

Self-diagnosis

• The self-diagnosis mode performs the microphone test.
• The self-diagnosis mode also diagnoses TEL adapter unit, TEL 

antenna and steering switch.

• Those results are indicated with voice guidance and displayed 

on the screen.

STEP2

Speaker adaptation data deleting

The speaker adaptation data deleting mode can delete the speaker 
adaptation data.

Hands-free phone system initialization

Hands-free phone system initialization mode can perform the ini-
tialization of hands-free phone system.

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000003356763

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independently). In CAN communication, control units are connected with 2
communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.
