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].
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 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.

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.

Description
AV CONTROL UNIT
• It is the master unit of the MULTI AV system, and it is connected to each control
unit by communication. It operates each system according to communication
signals from the AV control unit.
• AV control unit includes audio function and vehicle information function.
• It is connected to ECM, A/C auto amp. and combination meter via CAN com-
munication to obtain necessary information for the vehicle information function.
• It is connected to BCM via CAN communication transmitting/receiving for the
vehicle settings function.
• It inputs the illumination signals that are required for the display dimming con-
trol.
• It inputs the signals for driving status recognition (vehicle speed, reverse and
parking brake).
• The camera image signal is input from the camera control unit. The AV control
unit outputs camera image signal to the front display unit.
• BOSE amp. ON signal and sound signal are transmitted to BOSE amp.
• Power (signal VCC and inverter VCC) is transmitted to front display.
Without DVD entertainment system
• Auxiliary image and auxiliary sound signals are input from the auxiliary input
jacks.
With DVD entertainment system
• Composite image signal (auxiliary and DVD images) is input from the video
distributor.
• Sound signal (DVD and auxiliary sounds) is input from the DVD player.
