The diagnosis tests the following:

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. Select the red icon and check each diagnostic screen (refer to the description for diagnostic screens in the Unit Check).
Yellow
  • Errors that do not require hardware replacement, or the connection check is in the state which is not done. 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 is 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.

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.
