System Links
- 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.
- 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.
- When the diagnosis finishes, the icons turn different colors based on their test status. 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 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 Links screen, the gray icon turns green. NOTE: By selecting the HELP icon, you can see a description for each color. - 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.
