REAR VIEW MONITOR SYSTEM
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.

Part name Description
AV CONTROL UNIT Image on display is transmitted to rear view monitor image by serial communi-
cation between AV control unit and display unit.
 AV control unit recognizes the presence of camera system with camera con-
nection recognition signal.
DISPLAY UNIT Camera image signal is input from AV control unit.
 Rear view monitor image is changed by serial communication from AV control
unit.
CAMERA CONTROL UNIT Camera image signal is input from rear view camera. Camera image signal is
output to AV control unit.
 Power supply is transmitted to rear view camera.
 Superimposes the guiding line and predicted course line to the camera image
that outputs to AV control unit.
 Inputs the sensor signal from steering angle sensor, and then controls the pre-
dicted course line.
 Camera control unit is connected via AV communication.
REAR VIEW CAMERA The image of vehicle rear view is transmitted to camera control unit.
 It receives power supply from camera control unit and operates.
STEERING ANGLE SENSORSteering signal necessary for predicted course line control is transmitted to cam-
era control unit.

DIAGNOSIS SYSTEM (AV CONTROL UNIT)
Diagnosis DescriptionINFOID:0000000003765847
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 8-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.
 The self-diagnosis mode performs diagnoses on the AV control unit and NAVI control unit, connections
between system components as well as connections between NAVI control unit and GPS antenna and
between NAVI control unit and TEL antenna. Then it displays the diagnosis results on 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.

4. The trouble diagnosis initial screen is displayed, and then the
items of “Self Diagnosis” and “Confirmation/Adjustment” can be
selected.
SELF-DIAGNOSIS MODE
1. Start the self-diagnosis function and select “Self Diagnosis”.
- Self-diagnosis subdivision screen is displayed, and the self-diagnosis mode starts.
- The bar graph visible on the center of the self-diagnosis subdivision screen indicates progress of the trou-
ble diagnosis.
2. Diagnosis results are displayed after the self-diagnosis is com-
pleted. The unit names and the connection lines are color-coded
according to the diagnostic results.
NOTE:
 In case of connection malfunction of GPS or TEL antenna, diagnosis result follows “unit malfunction”
way to display.
 Replace AV control unit if “Self-Diagnosis did not run because of a control unit malfunction” is indicated.
The symptom is AV control unit internal error. Refer to AV-648, "
Exploded View".
- The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
SELF-DIAGNOSIS RESULTS
 Check the applicable display at the following table, and then repair the malfunctioning parts.
 The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between AV control unit and each unit and the internal operation of the AV control unit.
 Because the start condition of diagnosis function is a switch operation, the on board diagnosis function can-
not be started up if any malfunction is detected in the communication circuit between AV control unit and
multifunction switch.
