Reverse	OFF	Shift the selector lever to a position other than the "R" position	Changes in indication may be delayed. This is normal.

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

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 SW 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.

Count up method A

The counter resets to 0 if an error occurs when the IGN 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 IGN 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.

OCCURRENCE FREQUENCY

Display type of occurrence frequency	Error history display item
Count up method A	CAN communication line, control unit (CAN), AV communication line, control unit (AV communication)
Count up method B	Other than the above

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.
