Factory Diagnostic Screen in Line Diag

NOTE: If the vehicle left the factory in the factory diagnostic mode, or if the audio-navigation unit is replaced, you will see this screen every time you turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

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 diagnostic. until the proper confirmation sequence is done, the screen appears every time the vehicle is started.
