Navigation System Diagnostic Mode
Start-Up Procedure and Diagnostic Menu
NOTE: Check the vehicle battery condition first Battery Test.
1. Start the engine.
2. At the disclaimer screen use the audio-navigation unit hard buttons:
Press and hold the MAP/GUIDE, the DEST, and the CANCEL buttons for 3 seconds. The display screen goes directly to the Select Diagnosis Items menu shown.
* Self-Diagnosis Mode (runs the automatic diagnosis of the navigation system)
* Detail Information & Setting (allows you to manually diagnose the navigation system)
System Links
1. Select the Self-Diagnosis Mode from the Select Diagnosis Items menu. The message at the bottom of the screen flashes indicating the diagnosis is running.
2. Select the icon you want to diagnose to see the details of that diagnostic function.
The System Links function runs automatically and displays a flashing message at the bottom of the screen reminding you to have the engine running for the test. The diagnosis tests the following:
* Most of the wires connecting the external navigation components shown in the block diagram.
* The results from the various components shown in the block diagram.
* The microphone is tested by listening to the bong sound produced by the audio-navigation unit from the speakers when the diagnosis is started. This requires that the audio system be operating normally.
3. When the diagnosis finishes, the icons turn different colors based on their test status. Each icon color is explained in the table.
NOTE: By selecting the HELP icon, you can see a description for each color.
4. The indication on the screen may not change until you exit and reenter the Self-Diagnosis Mode. In some cases, you may have to restart the engine for the indication to change. After you repair the affected component or harness, repeat this diagnosis.
USB
This diagnosis displays directly from the System Links screen by selecting the USB icon.
This diagnosis checks the connection about USB harness.
If Connection shows NG, check for open in the wire between audio-navigation unit connector H (7P) terminals No. 6 (USB ADPT) and No. 7 (USB ON).
Flash Memory
This diagnosis displays directly from the System Links screen by selecting the Flash Memory icon.
This diagnosis checks the SD module status.
* Insert: Displays the result of the insert status about the SD module (OK; Inserted, NG; Not Inserted).
* Access: Displays the result of the access to the SD module (OK/NG). If NG, replace the SD module SD Module Removal and Installation, and recheck.
Factory Diagnostic Screen In Line Diag
NOTE: If the vehicle left the factory in the factory diagnostic mode, you will see this screen every time you turn on the ignition. Sometimes this screen also appears after you replace the audio-navigation unit with a new or remanufactured unit.
When an audio-navigation unit is powered up for the first time at the factory, the factory diagnosis screen (In Line Diag) appears. Normally the factory does the steps necessary to verify proper operation and terminate the factory diagnosis.
Until the proper confirmation sequence is done, the screen appears every time you turn on the ignition.
Follow the steps to prevent the screen from showing up in the future:
1. Press and hold the MAP/GUIDE, the DEST, and the CANCEL buttons for about 3 seconds. The Select Diagnosis Items screen appears.
2. Press and hold the MAP/GUIDE button until the In Line Diag CSF Setting screen appears.
3. Set the In Diag Setting to Complete, and make sure the CSF setting is ON, then select Return twice to exit the diagnostic mode. The In Line Diag should not appear again.

Monitor Check
Overview of the navigation display.
These screens allow you to troubleshoot the navigation display. Select the item you want to troubleshoot, and follow the diagnostic instructions.
* RGB Color
* Gray Tone
* White Raster
* Black Raster
* Color Pattern
* Monitor Adjustment
* Touch Panel Check
* Touch Panel Calibration
RGB Color
This screen verifies that the navigation display is receiving the video (R, G, B, and Composite sync) signals properly. The three primary colors should all appear without distortion. The combination of all three should produce a central white section. If the picture has lines in it, or scrolls horizontally or vertically, and any of the colors are missing, or scrolls horizontally troubleshoot for the color signal and composite sync problem.
Gray Tone
This screen checks problems with contrast. You should be able to see the changes from bar to bar across the scale. It is normal for the two bars on either side to appear the same. If you cannot see changes from bar to bar, replace the audio-navigation unit Audio-Navigation Unit Removal and Installation.
White Raster
This screen checks for pixels that may be dead (off). The entire display must be white. If there are dead pixels, replace the audio-navigation unit Audio-Navigation Unit Removal and Installation.
Black Raster
This screen checks for pixels that may be stuck on. The entire display must be black. If pixels are stuck on, replace the audio-navigation unit Audio-Navigation Unit Removal and Installation.
Color Pattern
The screen shows the colors being used for the map and menu screens. This is for factory use only. To check the color signal, use the RGB Color diagnosis.
Monitor Adjustment
This screen allows you to adjust the navigation display. Select the item you want to adjust.
* Navi: This allows you to center the navigation display.
* Rear Camera: This allows you to adjust the rearview camera guide lines. Not activated in this model (grayed out).
Navi
If you selected the Navi, use the joystick to move the picture up/down or left/right. then select the Set to save the selection. Do not adjust the monitor position unless directed by a service bulletin. The Default resets the display position to factory specifications.
Touch Panel Check
The panel touch sensing system consists of a touch sensitive resistive membrane covering the display. The screen has to be physically touched to make it work. The display has the capability of 479 touch locations (left to right), and 233 touch locations (top to bottom). The upper left hand corner is position (0, 0) and the lower right hand corner is (479, 233) as displayed. Touching anywhere on the screen displays the coordinate of the location, and cause the place you touch to display a + icon. If any area of the screen either does not respond, or responds at some other location when touched, then replace the audio-navigation unit Audio-Navigation Unit Removal and Installation.
NOTE:
* Unlike earlier screens that used infrared sensors, direct sunlight does not affect this test.
* A box appears after you touch the screen.
Touch Panel Calibration
The display screen uses a touch sensitive membrane. This means that every location of the entire surface of the display is touch sensitive. This diagnosis allows alignment of these touch locations with the location of the buttons images on the screen.
This should never need adjustment, and is used only by the factory to adjust the touch locations for parallax (the touch locations appear different when viewed at an angle). If you are directed to make an adjustment by the factory or other service information, follow this procedure:
* The screen consists of the + icons. Touch the center of the five + icons on order 1-5.
NOTE: Touch the center of the + icon correctly.
* To store any changes you make, touch the Set button.
* Select Return to exit the diagnosis.
