System DescriptionINFOID:0000000003882704
The audio system is equipped with following function. Each function can be operated with the multifunction
switch, preset switch, rear control switch or steering switch. It indicates the operation status of AUDIO to the
display unit.
FUNCTION DESCRIPTION
Operating Signal
Operation of the audio system can be performed via the multifunction switch, preset switch, rear control switch
or steering switch.
 Operating signal is transmitted to AV control unit via AV communication when it is operated by multifunction
switch, preset switch or rear control switch. The CD ejection operating signal is performed by hard-wire.
 Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering
switch.
Screen Display
 The display switching of the screen is performed by the communication signal between the display unit and
the AV control unit.
 The image signal to display operating condition is performed by RGB image signal, RGB area signal and
RGB image synchronizing signal.
AM/FM Radio Mode
 AM/FM radio tuner is built into AV control unit.
 AM/FM radio wave is received by glass antenna, next it is amplified by antenna amp., and finally it is input to
AV control unit. The FM sub antenna is installed on the rear window glass and the AV control unit is
received.
 Sound signal is input to AV control unit, and AV control unit outputs to each speaker.
CD Mode
 CD function is built into AV control unit.

CAMERA IMAGE OPERATION PRINCIPLE
 Power is supplied to rear view camera from camera control unit and the rear view camera outputs the cam-
era image to camera control unit when selector lever is set to reverse position and the reverse signal on
camera control unit is input.
 Camera control unit superimposes the guiding line and predicted course line to the image from rear view
camera and outputs to display unit. In this case, the reverse signal is also input to AV control unit. Therefore,
AV control unit recognizes the selector lever as in the reverse position. And then AV control unit switches the
image displayed by the communication signal between AV control unit and display unit with the camera
image.
 AV control unit outputs camera image signal that is inputted from camera control unit to display unit.
 Camera control unit controls the direction and distance of predicted course line according to the sensor sig-
nal from steering angle sensor.
 AV control unit determines whether rear view camera is equipped or not, based on the presence of camera
connection recognition signal. It switches to rear view monitor image at the time of reverse signal input when
rear view camera is equipped.

PREDICTED COURSE LINE OPERATION PRINCIPLE
Detection Of Steering Rotation Direction
Camera control unit detects the rotation direction of steering according to the phase difference of two pairs of
pulse signals (sensor signal 1 and sensor signal 2) input from steering angle sensor.
Detection Of Steering Neutral Position
The sensor signal 3 input from steering angle sensor is generated at 1 pulse per 1 rotation of the steering
wheel. Camera control unit detects the steering neutral position from this pulse.
Correction Of Steering Neutral Position
Camera control unit corrects the steering neutral position during driving according to the vehicle speed signal
and sensor signal.

MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION
The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be
checked.
Self-diagnosis Mode
 Press the “BACK” switch and the “UP” switch of the 4-direction
switches within 10 seconds after turning the ignition switch from
OFF to ACC and hold them for 3 seconds or more. Then the
buzzer sounds, all indicators of the preset switch illuminate, and
the self-diagnosis mode starts.
 The continuity of each switch at the ON position can be checked
by pressing the switch. The buzzer sounds if the switch is normal.
NOTE:
The hazard switch and disk eject switch cannot be checked.
Finishing Self-diagnosis Mode
Self-diagnosis mode is canceled when turning the ignition switch OFF.
MULTI AV SYSTEM ON BOARD DIAGNOSIS FUNCTION
 The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit
performs a diagnosis for each unit in the system during the on board diagnosis.
 Perform a CONSULT-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display
anything, the multifunction switch does not function, etc.
ON BOARD DIAGNOSIS
Description
 The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and
a confirmation/adjustment mode for operating manually.
 Self-diagnosis mode performs the AV control unit diagnosis and the connection diagnosis between each of
the units that make up the system, and it indicates the results to the display.
 The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and
set values, as well as to monitor the system error records and system communication status. The check,
modify or adjust actions generally require human intervention and judgment (the system cannot make judg-
ment automatically).
