System Links

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..." While the diagnosis is running, do not turn the vehicle to the OFF (LOCK) mode.

NOTE:  The system cannot complete a full diagnosis unless the engine is running.The diagnosis tests the following:

• Most of the links connecting the navigation components are shown in the block diagram.
• The results from the various components shown in the block diagram.
• The audio-navigation unit outputs the "Ba Ba 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.

2. 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 - Refer to: How To Troubleshoot The Navigation System (Without Auto Idle Stop System) (2015-17)  or How To Troubleshoot The Navigation System (With Auto Idle Stop System) (2015-17)  or How to Troubleshoot the Navigation System (2018-19) .
Yellow	Errors that do not require hardware replacement, such as leaving the vehicle in 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 navigation 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 Car Status icon anytime shows gray.

*: The F-CAN icon and the B-CAN icon turns red when the vehicle is in 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.

3. Rotate the interface dial to select the icon when you want to diagnose. Press in the interface dial knob 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.
