Factory Diagnostic Screen In Line Diag

If the vehicle left the factory in the factory diagnostic mode, you will see this screen every time you turn the vehicle to the ON mode. Sometimes this screen also appears after you replace the audio-navigation unit with a new or remanufactured unit.

When the audio-navigation unit is powered up for the first time at the factory or sometimes a remanufactured audio-navigation unit is installed, the factory diagnosis screen (In Line Diag) appears. Normally the factory does the steps necessary to verify proper operation and terminate the factory diagnosis. Until the proper confirmation sequence is done, the screen appears every time you turn the vehicle to the ON mode.
