DIAGNOSIS SYSTEM (AV CONTROL UNIT)
The tint of the color bar indication is as per the following list if RGB signal error is detected.
Vehicle Signals
A comparison check can be made of each actual vehicle signal and
the signals recognized by the system.
Speaker Test
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-156, "
WITHOUT INTELLIGENT AIR CONDITIONER SYSTEM : CONSULT-III Function"for
details.
Camera Cont.
Refer to AV-56, "System Description".

RGB (B: BLUE) SIGNAL CIRCUIT (AV CONTROL UNIT TO DISPLAY UNIT)
DescriptionINFOID:0000000003882743
Transmit the image displayed with AV control unit or NAVI control unit with RGB signal to the display unit.
Diagnosis ProcedureINFOID:0000000003901208
1.CHECK CONTINUITY RGB (B: BLUE) SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect display unit connector and AV control unit connector.
3. Check continuity between display unit harness connector and AV control unit harness connector.
4. Check continuity between display unit harness connector and ground.
Is inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK RGB (B: BLUE) SIGNAL
1. Connect display unit connector and AV control unit connector.
2. Turn ignition switch ON.
3. Check signal between display unit harness connector terminal and ground using an oscilloscope.
Is inspection result normal?
YES >> Replace display unit.
NO >> Replace AV control unit.
