Special Note for Trouble DiagnosisBKS0027V
Prior to performing trouble diagnosis, make sure there are no corresponding description in the “Example of
Symptoms Possible No Malfunction”. Refer to AV- 111 , "
Example of Symptoms Possible No Malfunction" .
A/C and AV Switch Self-Diagnosis FunctionBKS00280
Performing self-diagnosis makes it possible to check operation of A/C and AV switch indicator (LED) and other
switches.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch OFF.
2. With three switches (DEF, REC/FRE and MODE) pressed simul-
taneously, turn the ignition switch to ACC.
DIAGNOSIS FUNCTION
The following are checked:

All the indicators (LED) in the A/C and AV switch.

Continuity of the switches by sounding the buzzer when pressing the A/C and AV switch.

Continuity of the switches by sounding the buzzer when pressing the rear audio control switch.
NOTE:

Indicators (LED) of REC/FRE switch change to “FRE” → “REC” → “FRE” every time the REC/FRE switch
is pressed. (These two do not turn on at the same time.)

Impossible to check rear window defogger switch operation (No beep sound even under normal status).
EXITING THE SELF-DIAGNOSIS MODE

Turn ignition switch OFF.

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.
