Factory diagnostic screen In Line Diag

NOTE: If the vehicle left the factory in the factory diagnosis mode, or if the navigation unit is replaced, 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 control unit is powered up for the first time at the factory, the factory diagnosis screen (In Line Diag) appears. Normally the factory performs the steps necessary to verify proper operation and terminate the factory diagnostic.

Until the proper confirmation sequence is performed, the screen appears every time the vehicle is started.
