There are two ways to enter the diagnostic mode:

1. Connect the SCS service connector to the

navigation service connector located in the trunk.
Turn the ignition switch to the ON (II) position. The
display will go directly to the diagnostic menu
screen.

NOTE: When finished troubleshooting, make sure
to remove the SCS service connector.

2. Turn the ignition switch ON (II). Use the navigation

display hard buttons, press and hold the 3 buttons
(Menu, Map/Guide, and cancel), and keep them
pressed for about 5 seconds. The display screen
will go directly to the Select Diagnosis Items menu.

3. After the display changes to the Diagnostic items

menu, select the item you want to check, and the
diagnostic will start. To return to the previous
screen, select ‘‘Return’’.

NOTE: If the vehicle left the factory in the factory
diagnosis 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, the ‘‘factory diagnosis‘‘ screen
(In Line Diag) shows up. 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 will show up every time the vehicle is started.

Follow the steps below to prevent the screen from
showing up in the future:

• Hold down the buttons (Menu

Map/Guide

Cancel) for about 5 seconds (the ‘‘Select Diagnosis
items’’ screen will appear).

• Hold down the Map/Guide button for 5

10 seconds

(A screen with a ‘‘Complete’’ button, will appear).

• Touch ‘‘Complete’’, and then the ‘‘Return’’ button (the

system may re-boot).

• Restart the vehicle, and confirm normal operation by

completing the ‘‘TQI of the Navigation System’’
Service Bulletin.

• This diagnostic tests the cables connecting the

navigation components. Ensure that the ignition
switch is in the ON (II) position. When the diagnostic
begins, you hear a ‘‘bong‘‘ sound. The system is in a
‘‘Detecting’’ mode, and is waiting for all items in
white to be tested. This includes the voice control
switch (TALK/BACK buttons), and microphone. Press
the TALK button on the steering wheel, and in a
normal voice, say ‘‘testing‘‘. The talk indicator on the
screen should turn green, and the voice level
indicator should move to at least the 6th bar to pass.
Next, press the BACK button. The ‘‘Cancel‘‘ indicator
should turn green.

• If all of the communication lines connecting the

system components, and the TALK/BACK buttons/
microphone check out OK (all block diagram items
green), then the ‘‘OK’’ indicator turns green.

• If there is a problem with the system, the faulty

system component item turns red, and the screen will
show ‘‘NG’’ in red. Use the troubleshooting index,
and other diagnostic screens to help locate the
problem.

• The indication on the screen may not change until

you cycle the ignition switch. After repairing the
affected cable or system, repeat this diagnostic.
NOTE: Green boxes and green ‘‘OK’’ indicate that the
communications lines (cables) are intact. This
diagnostic does not necessarily imply that the
individual components are functioning properly. For
instance, the GPS antenna wire may be crushed, but
still show as ‘‘green’’. A road test, or other diagnostic
may be necessary to find the problem. The rearview
camera feature is optional. If the camera is not
installed, the ‘‘rear camera’’ icon is yellow/orange.
When the camera is installed the icon is green. If the
icon is not green with the rearview camera installed,
check for opens or shorts in the rearview camera
cable.

• Select ‘‘Return’’ to return to the Diagnostic Menu or

the ‘‘Exit Diag’’ button to exit.

NOTE:

• The Mic Level indicator must reach the 6th bar or

greater to pass the test.

• If the XM link is red or flashing red, go to audio

system symptom troubleshooting, or see XM (HIP)
diagnostic screen.
