How to Check Error History (Navigation DTCs)
NOTE: The navigation DTCs cannot be retrieved with the HDS.
The Error History feature is to record intermittent audio/navigation issues that occur while the customer is using the system. Sometimes the customer complaint cannot be duplicated. The error history may record the information needed to diagnose the problem. To check the error history:
1. Turn the vehicle to the ON mode
2. At any screen except the HOME screen, press and hold the EJECT button, the POWER (
) button, and the HOME button until the Select Diagnosis Items menu screen is displayed.
NOTE: When HOME screen is displayed, the HOME button illumination goes out, and is hard to check.
