Component DescriptionBKS0027K
DISPLAY CONTROL UNIT
Display control unit draws a status of the audio system and air
conditioner system, a TRIP screen, a FUEL ECONOMY screen,
etc., and transmits the image signals to the display screen.
It receives operation signals of audio system and air conditioner
system from A/C and AV switch, and transmits the operation sig-
nal of audio system to the audio unit through the communication
line and transmits the operation signal of air conditioner system
to the unified meter and A/C amp. through CAN communication.
Display signal from audio unit is transmitted to display control
unit through the communication line, and then the operating
state of the audio system is displayed in the screen.
Display signal from unified meter and A/C amp. is transmitted to
display control unit through the CAN communication, and then the operating state of the air conditioner
system is displayed in the screen.
DISPLAY
Images on the display include RGB image and rear view image
displayed when setting the select lever to R range.
Display control unit controls images on the display.
A/C AND AV SWITCH
A/C and AV switch, an integrated combination of audio system
and air conditioner system switches, are adopted.
Operation signal of audio system is transmitted to the audio unit
through display control unit with the communication line.
Operation signal of air conditioner system is transmitted to uni-
fied meter and A/C amp. through display control unit with CAN
communication.
REAR VIEW CAMERA
Rear view camera transmits rear view image signals to the dis-
play screen through the rear view camera control unit, when
reverse signal is input.
The rear view image is a mirror image reversed left and right
that is the same as seeing rear side with a room mirror.

On Board Self-Diagnosis FunctionBKS0027W
DESCRIPTION
Trouble diagnosis function of system has a self-diagnosis mode by automatic operation and a confirma-
tion mode by manual operation.
Self-diagnosis mode checks for connections between the units constituting this system, analyzes each
individual unit at the same time, and displays the results on the display.
Confirmation mode displays trouble diagnosis that require an operation and a judgment by a human
(auto-decision cannot be performed by the system), and an error history of system.
DIAGNOSIS ITEM
Mode Description
DCU Failure Diagnosis
Display control unit diagnosis
Analyzes connection between the display control unit and each unit, and operation of
each unit.
DCU
ConfirmationDCUDisplay DiagnosisColor tone and shading of the display control unit-generated image can be checked by
the display of a color bar and a gray scale.
Vehicle SignalDiagnosis of signals that are input to display control unit can be performed for speed sig-
nal, Light, IGN and Reverse.
History of ErrorMalfunctions that occurred in the past are displayed, along with the number of times each
has occurred.
Software Version Software version of each unit is displayed.
HVAC Self-diagnosis of air conditioner system is performed.
CAN Diagnosis The transmitting/receiving of CAN communication can be monitored.

Vehicle Signal
A comparison check can be made of each actual vehicle signal and
the signals recognized by the display control unit.
History of Error
Diagnosis results of self-diagnosis depend on if any error occurred
during the time after selecting “DCU Failure Diagnosis” until self-
diagnosis results is displayed.
Meanwhile, when an error occurs before selecting “DCU Failure
Diagnosis”, and if an error does not occur until self-diagnosis results
is displayed, a diagnosis result is judged as normal.
Consequently, a diagnosis needs to be performed with “History of
Error” for the past error that is not available with self-diagnosis.
“History of Error” stores error occurrences up to 50, and errors after
the 51st are displayed as the 50th.
