- Start the engine.
- Press and hold the MAP/GUIDE, MENU, and CANCEL buttons for 3 seconds.
- When the Select Diagnosis Items menu is displayed, select Self-Diagnosis Mode.
- When the audio-navigation unit has hard codes stored, the Error History icon appears yellow when the Self Diagnosis mode (System links) screen is displayed. When no hard errors are stored, the icon appears gray to green. To view the errors with their DTC codes, select the error history icon.
- Select Hard ErrorNOTE: Soft errors are for factory use only.
