the engine running, and if it shows normal, the
system is OK at this time.

Navigation System

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.
