Display Diagnosis

Vehicle Signals

A comparison check can be made of each actual vehicle signal and the signals recognized by the system.

Diagnosis item	Display	Vehicle status	Remarks
Vehicle speed	ON	Vehicle speed >= 8 km/h (5 MPH)	Changes in indication may be delayed. This is normal.
	OFF	Vehicle speed < 8 km/h (5 MPH)
Parking brake	ON	Parking brake is applied.
	OFF	Parking brake is released.
Lights	ON	Block the light from the auto light optical sensor when the lighting switch is 1st or 2nd.	-
	OFF	Either of the following conditions. Lighting switch is OFF Expose the auto light optical sensor to light when the lighting switch is 1st or 2nd.
Ignition	ON	Ignition switch is ON.	-
	OFF	Ignition switch is in ACC position.
Reverse	ON	Selector lever is in "R" position.	Changes in indication may be delayed. This is normal.
	OFF	Selector lever is in other than "R" position.
Side view Switch	OFF	-	This item is displayed, but cannot be monitored.
Room Lamp	OFF	-	This item is displayed, but cannot be monitored.

Speaker Test

Select "SPEAKER DIAGNOSIS" to display the Speaker Diagnosis screen. Press "Start" to generate a test tone in a speaker. Press "Start" to generate a test tone in the next speaker. Press "Stop" to stop the test tones.

Navigation

STEERING ANGLE ADJUSTMENT

The steering angle output value detected with the gyroscope is adjusted.

SPEED CALIBRATION

During normal driving, distance error caused by tire wear and tire pressure change is automatically adjusted for by the automatic distance correction function. This function, on the other hand, is for immediate adjustment, in cases such as driving with tire chain fitted on tires.

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 situation.

The error record displays the time and place of the most recent occurrence of that error. However, take note of the following points.

• If there is a malfunction with the GPS antenna circuit board in the AV control unit, the correct date and time of occurrence may not be able to be displayed.
• Place of the error occurrence is represented by the position of the current location mark at the time an error occurred. If current location mark has deviated from the correct position, then the place of the error occurrence cannot be located correctly.
• The frequency of occurrence is displayed in a count up manner. The actual count up method differs depending on the error item.

Count up method A

• The counter resets to 0 if an error occurs when ignition switch is turned ON. The counter increases by 1 if the condition is normal at a next ignition 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 ignition switch is ON. The counter will not decrease even if the condition is normal at the next ignition 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".

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)
Count up method B	Other than the above
