System Diagnosis Mode
Start-up procedure and Diagnosis Menu
There are two ways to enter the diagnostic mode:
1. Connect the SCS connector (see step 2 on page
23-52) to the navigation service connector focated
in the trunk. Turn the ignition switch to the ON (II)
position. The display will go directly to the diagnostic
menu screen shown below.
Note: when finished troubleshooting, make sure to
remove the SCS connector!
2. Turn the ignition switch to the ON (II) position.
Use the navigation display hard buttons as described
below:
A. If the battery has not been disconnected, then
press and hold the 3 buttons (Menu, Map/Guide,
and Cancel), and keep them pressed for
approximately 5 seconds. The display screen will
go directly to the "Select Diagnosis Items" menu
shown below.
B. If the battery was disconnected and reconnected
prior to this test, hold down the Menu and Zoom
Out buttons at the "Code" or "GPS Acquire"
screen. The display will go to the "Navi System
Link" screen. Push the joystick to go to the
"Functional Setup menu," then touch the Return
icon to get to the "Select Diagnosis Items" menu.
Note: This only allows access to the diagnostic
screens. All other navigation functions are
disabled.

gation components. Ensure that the ignition switch is
in the ON (II) position. When the diagnostic begins, a
"bong" sound is heard. The system is in a
"Detecting" mode, and is waiting for all items in
white to be tested. This includes the voice control
switch, and microphone. Press the TALK button on
the voice control switch, and in a normal voice, say
"testing". The Talk indicator on the screen should
become green, and the voice level indicator should
th
move to the 6 bar to pass. Next, press the BACK
button. This should cause the Cancel indicator to go
green.
• If all of the communication lines connecting the
system components, and the voice control
switch/microphone check out OK (all block dia-
gram items green), then the OK indicator will
become green.
• If there is a problem with the system, the faulty
system component item will change to red, and
the screen will show "NG" in red. Use the trou-
bleshooting index, and other diagnostic screens to
help locate the problem.
• The indication on the screen will not change until
the ignition switch is cycled. 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.
• Touch the Exit Diag icon to exit.
