Navigation System Diagnostic Mode
NOTE: The screens detail indicated may change depending on equipment or specification.

Start-Up Procedure and Diagnostic Menu

NOTE: Check the vehicle battery condition first.

1.
Turn the vehicle to the ON mode. If needed, start the engine.

2.
Press and hold the POWER (enu_4460341_1.0) button, the MENU button, and the DAY/NIGHT (enu_1740914_1.0) button until the Select Diagnosis Items menu screen is displayed:
Self-Diagnosis Mode (runs the automatic diagnosis of the navigation system)
Detail Information & Setting (allows you to manually diagnose the navigation system)
Displaying Select Diagnosis Items Menu Screen
System Links

NOTE: This diagnosis must have the engine running.

1.
Select the Self-Diagnosis Mode from the Select Diagnosis Items menu. The message at the bottom of the screen flashes indicating ‘‘Diagnosis in progress...’’ and a bong sound is heard from the speakers. While the diagnosis is running, do not turn the vehicle to the OFF (LOCK) mode.

NOTE: The display differs depending on the equipments and specifications.

2.
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 audio-navigation unit checks the microphone 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.

NOTE: By selecting the Help icon, you can see a description for each color.

Icon Colors
Description
Green
The system ran a diagnosis and the results are OK.
Red*
Errors that require replacement of hardware or harness. Examples are connection error or memory diagnosis errors. Check for hard error codes. Check for and troubleshooting all DTCs before continuing.
Yellow
Errors that do not require hardware replacement, such as leaving the vehicle in the ACCESSORY mode, or because of a missing accessory.
When the audio-navigation unit detects a failure, and stores DTC, the Error History icon turns yellow.
White
The diagnosis is running. The screen functions are locked out while the diagnosis runs.
Gray
The system cannot automatically check this function. You have to select the diagnosis item and manually do additional testing, like checking the audio-navigation unit buttons in the Hard Key test. When you complete the Hard Key test and return to the System Links screen, the gray icon turns green.
The Vehicle Status icon anytime shows gray.
When the audio-navigation unit does not store DTCs, the Error History icon shows gray.
*: The F-CAN icon and the B-CAN icon turns red when the vehicle in the ACCESSORY mode. Check the System Links with the engine running, and if the F-CAN icon and the B-CAN icon turns green, the system is OK at this time. If they remain red, check for and troubleshoot and DTCs before continuing.

4.
Select the icon to see the details of that diagnostic function. The icon colors 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.
Factory Diagnostic Screen In Line Diag

If the vehicle left the factory in the factory diagnostic mode, you will see this screen every time you turn the vehicle to the ON mode. Sometimes this screen also appears after you replace the audio-navigation unit with a new or remanufactured unit. 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 the vehicle to the ON mode.

NOTE: The system cannot complete a full diagnosis unless vehicle is in the ON mode.

1.
Select the Start Diag icon to check the connection between the audio-navigation unit and related components. When the connection diagnosis is in progress, the icon (A) indicates Detecting... , and each icon turns white. If the connection is OK, the icon turns green. If the connection is NG, the icon turns red. Check for connection between the audio-navigation unit and related unit on the failure connection line.

NOTE: When the item is a variation equipment, the icon shows yellow, and it is not reflected in diagnosis.
2.
If the connection diagnosis is finished, press the steering commander switch buttons (the TALK button, the PICK-UP button, and the HANG-UP/BACK button) to check the HFL switch. As each button is pressed, the corresponding icon on the display should turn green. If all icons do not turn green, Check for gauge control module DTCs.

3.
Press the TALK button, and within 5 seconds in a normal voice say ' 'testing' ' toward the microphone in the roof console.

4.
If all the diagnosis are OK, the icon (A) indicates OK. Select the EXIT Diag icon to exit the diagnostic mode. The In Line Diag should not appear again.
Forced Completing of In Line Diag

Follow the steps below to prevent the screen from showing up in the future:

1.
While displaying the In Line Diag screen, press and hold the POWER (enu_4460341_1.0) button, the MENU button, and the DAY/NIGHT (enu_1740914_1.0) button until the Select Diagnosis Items menu screen is displayed.

2.
While displaying the Select Diagnosis Items menu screen, press and hold the MENU button until the In Line Diag setting screen is displayed.

3.
Set the Inline Diag Setting to Completion. The system restarts and a normal start-up process occurs. The In Line Diag should not appear again.

Select the Import icon to move the two files stored by the Export process from the USB device to the new audio-navigation unit. Select the Yes icon on the Import User Data Confirmation screen. When the transfer is finished (a few seconds) the system automatically reboots. After the system reboots, remove the USB device from the USB port.

NOTE: If the Import icon is grayed out, check if the Model and the Program Version shown on the DA Unit and Version screens are the same.
LaneWatch

This diagnosis checks the LaneWatch detail status.
If Connection shows NG, check for hard error codes.
Error Status: Indicates LaneWatch camera status OK or NG. If Error Status shows NG, replace the LaneWatch camera. When the LaneWatch camera is disconnected, the status shows hyphen ( - ).
If Error Status shows OK, press the MENU button to display the LaneWatch camera image. To return to the previous screen, press the MENU button again.
LaneWatch Switch: LaneWatch switch status on or off. When the LaneWatch switch is pressing, the status shows ON. When the LaneWatch switch is released, the status shows hyphen ( - ).

GPS Information

This screen shows the current status of GPS reception. The circular diagram shows the current location of the GPS satellites (yellow numbers) as they would appear in the sky. The outer circle represents the horizon (0 degrees elevation). The middle and inner circles represents 30 and 60 degrees respectively. The very center of the diagram (90 degrees elevation) is directly overhead. Nearby obstructions, like tall buildings will block satellites in that direction. That is why it is necessary to be in an open area to effectively troubleshoot GPS reception issues. There are always at least 24 active GPS satellites in orbit. Because satellites fail, and have to be removed from service, spares are always parked in orbit, ready to be activated. This is why the PRN can be greater than 24.

NOTE: When you use this screen for troubleshooting, park the vehicle outside, away from buildings, tall trees, and high tension wires for at least 10 minutes with the engine running.
The Number of Satellites box shows the number of acquired satellites (maximum of 12). It should contain three or more icons.
The Current Position shows latitude, longitude, and elevation (in feet). If there are less than four satellites, the elevation can be grossly inaccurate.
The date/time field shows the current date, and also a time that includes daylight savings and other offsets entered by the customer in Setup screen 2 Adjust Time Zone/Clock.
