Factory diagnostic screen In Line Diag
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
If the vehicle left the factory in the factory diagnostic mode, you will see this screen every time you turn the ignition switch to ON (II). You may also see this screen if the audio-navigation unit is replaced.
When the audio-navigation unit is powered up for the first time at the factory or sometimes when 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.
Follow these steps to prevent the screen from showing up in the future:
- Press and hold the MENU, MAP/GUIDE, and CANCEL buttons at the same time until the Select Diagnosis Items screen comes up. Then release the buttons.
- Press and hold the MAP/GUIDE button until the In line Diag Setting screen appears.
- Set the In Diag Setting to Complete, then select Return twice to exit the diagnostic mode.
