System Diagnostic Mode (cont’d)
The System Links function runs automatically and
displays a flashing message at the bottom of the
screen reminding you to have the engine running
for the test. The diagnostic tests the following:
 Most of the wires connecting the navigation components shown in the block diagram.
 The results from the various components shown in the block diagram.
 The microphone is tested by listening to the bong sound produced by the navigation unit from the
speakers when the diagnostic is started. This
requires that the audio system be operating
normally.
When the diagnostic finishes, the icons turn
different colors based on their test status. The color
definitions are shown below and can also be seen
by selecting Help on the System Links screen.
The indication on the screen may not change until
you exit and reenter the Self-Diagnosis mode. In
some cases, you may have to restart the engine for
the indication to change. After you repair the
affected component or harness, repeat this
diagnostic. Explanation of each icon
Each icon color is explained in the table below.
Green The system ran a diagnosis and the results are OK.
Red Errors that require replacement of hardware or harness. Examples
are connection error or memory
diagnosis errors. Troubleshooting
for DTCs.
Yellow Errors that doesn’t require hardware replacement, such as an
open display cover, an incorrect
DVD, leaving the vehicle in
ACCESSORY (I), or because of a
missing accessory, like the
rearview camera.
White The diagnosis is running. The screen functions are locked out
while the diagnosis is runs.
Gray The system cannot automatically check this function. You have to
select the diagnosis item and
manually do additional testing,
like checking the navigation
buttons in the Hard Key test.
When you complete the Hard Key
test and return to the System
Links menu, the gray icon turns
green.
NOTE: By selecting the HELP icon, you can see a
description for each color.

(Navi will check internal function. connections, etc.
Perform this test with vehicle stopped and engine running.)
(Individual Diagnostic screens to confirma specific diagnostic screen.)
NOTE: If the vehicle left the factory in the factory
diagnostic mode, or if the navigation unit is replaced
you will see this screen every time you turn on the
ignition.
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.
Follow the steps below to prevent the screen from
showingupinthefuture:
 Press and hold the buttons (MENU, MAP/GUIDE, and CANCEL) for about 3 seconds. The Select Diagnosis
items screen appears.
 Press and hold the MAP/GUIDE button for 5 10 seconds. A screen with a Complete button,
appears.
 Press complete, then Return, and then shut the key off for 5 seconds. Do not disconnect the battery
during this period as the unit is saving the setting to
the SRAM memory. The In Line Diag should not
appear again.
 Restart the vehicle, and confirm normal operation by completing the TQI of the Navigation System Service
Bulletin. These section allows you to run a specific diagnostic
and allows additional setting choices for some screens
that are not shown when selecting an icon from the
System Links screen.
When you select the menu item Detail Information &
Setting menu, the main diagnosis menu is displayed.

Overview of navigation display
The illumination input from the gauge brightness
control provides back lighting for the buttons
surrounding the screen.
These screens allow you to troubleshoot the navigation
display. Select the item you want to troubleshoot, and
follow the diagnostic instructions. This screen verifies that the display unit is receiving the
video (R, G, B and Composite sync) signals properly.
The three primary colors should all appear without
distortion. The combination of all three should produce
a central white section. If the picture has lines in it, or
scrolls horizontally or vertically, and any of the colors
are missing, troubleshoot for a composite sync and
color signal problem (see page 23-339).
This screen diagnoses problems with contrast. You
should be able to see the changes from bar to bar
across the scale. It is normal for the two bars on either
side to appear the same. If you can’t see changes from
bar to bar, replace the navigation unit.
