Factory diagnostic screen In Line Diag: Notes
NOTE:
If the vehicle left the factory in the factory diagnostic mode, you will see this screen every time you turn on the ignition. You may also see this screen if you recently replaced the navigation unit.
When a navigation unit is powered up for the first time at the factory or after replacement with a new or remanufactured navigation unit, 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.
