System Link

Enter this screen by connecting the SCS service connector or by selecting Self-Diagnosis Mode from the navigation screen main menu. The message at the bottom of the screen flashes indicating the diagnostic is running.
NOTE:
- The system cannot complete a full diagnosis unless the engine is running.
- DTC 1801 can be stored when the ignition switch is in ACCESSORY (I), or press the engine start/stop button to select the ACC mode. With the ignition switch is in ACCESSORY (I), or press the engine start/stop button to select the ACC mode, the AcuraLink is turned off and the audio-navigation unit loses communication and stores DTCs. Therefore, there is a possibility that the system is normal even though DTC 1801 is stored. Check System Link with the engine running, and if it appears normal, the system is OK at this time.

Rotate the interface dial to select the icon you want to diagnose. Push in the selector to see the details of that diagnostic function.

The System Link 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 diagnostic tests the following:

Most of the wires 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 tests 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.

When the diagnosis finishes, the icons turn different colors based on their test status. The color definitions are shown below and can also be seen by selecting Help on the System Link screen.

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.

Each icon color is explained in the table.

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. Troubleshoot for navigation DTCs.
Yellow	Errors that do not require hardware replacement, such as leaving the vehicle in ACCESSORY (1) or ACC mode, or because of a missing accessory.
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 Link menu, the gray icon turns green.

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