Function Check
- Panel & Steering Switch Check Mode
Once the screen is displayed, press the push switches to check that the number of pushed switches matches the number shown in pushed SW.
If the number of SW does not match, SW conditions are not properly recognized. Therefore, perform inspection for unrecognized switches.
In addition, turn the rotary switch clockwise or counterclockwise to check that the screen indicates correct status according to the operation. If the screen display does not match the actual operation, the rotary SW may be faulty. Perform inspection for the rotary SW.

NOTE: The following shows information to be displayed and its description.Item Contents + (Cursor) Appears when the screen is touched.
The displayed white-outlined + (cursor) stays on, even when a touching finger is removed, until the screen is switched. - Microphone Check
With the microphone input level screen displayed, make sound toward the microphone.
Fluctuate the sound volume to check that the microphone input level changes accordingly.
If the input level does not become green or the input level does not change even when the sound volume is fluctuated, the microphone may be faulty.
NOTE: The microphone input function is enabled while this screen is displayed.- The sound volume is indicated in eight levels.
The maximum input volume of microphone is equally divided into eight levels from level 0 to level 7.
- The microphone input level is sampled every 100 ms, and the result is indicated in eight levels.
Display of the input level is also updated every 100 ms.
The microphone input level gauge is updated even during recording.

- System Sensors Check
GPS related check: Status of the GPS signal reception can be checked. When there is faulty in reception status, position detection or date indication, re-check the reception status at a location with a fine view and no obstacles around that will interrupt the signal reception. When normal condition is still not obtained, the GPS antenna may be faulty.
- GPS/Reception number: Normal when it is indicated in blue.
- GPS/Status: Normal when OK is indicated.

- Drive the vehicle at 9 km/h (6 MPH) or more.
- Check that SPD indicates vehicle speed that is almost equivalent to the figure displayed on the combination meter.
- Vehicle speed is not displayed. Or, when different vehicle speed is indicated, check if CAN system DTC is stored. If so, perform the diagnosis according to the DTC. When CAN system DTC is not stored, check if the DTC related to the vehicle sensor is stored for the VDC system, and perform inspection according to the procedure. If no fault is found with the CAN system and vehicle speed sensor, and the vehicle speed is displayed on the combination meter, the unit itself may be faulty.
Gyro sensor related check: Status of the Gyro sensor signal can be checked. If fault is found with the Gyro sensor related indications, the main unit could be faulty.
- Gyro sensor/Gyro Voltage: Shake the vehicle to the left and right to check that the voltage changes.
- Gyro/Distance correction study situation: Study situation can be checked.
- Reset: Press and hold the Reset button for three seconds to reset the pulse count of SPD, relative bearing of Gyro sensor, relative angle of inclined angle sensor.NOTE: The following shows information to be displayed and its description.
