The tint of the color bar indication is as per the following list if a 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.
*: Squawker
Climate Control
Refer to “HEATER & AIR CONDITIONING CONTROL SYSTEM” for details.
Error History
The self-diagnosis results are judged depending on whether any error occurs from when “Self-diagnosis” is
selected until the self-diagnosis results are displayed.
However, the diagnosis results are judged normal if an error has occurred before the ignition switch is turned
ON and then no error has occurred until the self-diagnosis start. Check the “Error Record” to detect any error
that may have occurred before the self-diagnosis start because of this condition.

DIAGNOSIS SYSTEM (AV CONTROL UNIT)
Count up method A
• The counter resets to 0 if an error occurs when the ignition switch is turned ON. The counter increases by 1
if the condition is normal at the next IGN ON cycle.
• The counter upper limit is 39. Any counts exceeding 39 are ignored. The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT-III.
Count up method B
• The counter increases by 1 if an error occurs when the ignition switch is ON. The counter will not decrease
even if the condition is normal at the next IGN ON cycle.
• The counter upper limit is 50. Any counts exceeding 50 are ignored. The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT-III.
Error item
Error items may be displayed simultaneously according to the cause. If error items are displayed simulta-
neously, the cause can be detected by the combination of display items.

DIAGNOSIS SYSTEM (AV CONTROL UNIT)
Vehicle CAN Diagnosis
• CAN communication status and error counter is displayed.
• The error counter displays “OK” if a malfunction was not detected
in the past and displays “0” if a malfunction is detected. It increases
by 1 if the condition is normal at the next ignition switch ON cycle.
The upper limit of the counter is 39.
• The error counter is erased if reset.
AV COMM Diagnosis
• Displays the communication status between AV control unit (mas-
ter unit) and each unit.
• The error counter displays “OK” if any malfunction was not
detected in the past and displays “0” if a malfunction is detected. It
increases by 1 if the condition is normal at the next ignition switch
ON cycle. The upper limit of the counter is 39.
• The error counter is erased if reset.
Camera Cont.
The two functions of “Connection Confirmation” and “Adjust Offset of Rear View Camera” are available.
CONNECTION CONFIRMATION
The steering angle sensor, reverse signal and vehicle speed sensor
can be inspected.
