System Diagnostic Mode (cont'd)
Factory diagnostic screen In Line Diag
NOTE: If the vehicle left the factory in the factory
diagnostic mode, you will see this screen every time
you turn on the ignition.
When a navigation control 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) shows up. 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 will show up every time the vehicle is started.

unit over its own GA-Net bus. Information sent by the
navigation unit to the display unit includes
commands to control the LCD back light.
• The security system protects the navigation display
unit by daisy-chaining the security signal through it,
and then passing the signal to the audio unit.
• The illumination input from the gauge brightness
control provides back lighting for the buttons
surrounding the screen.
