• This diagnostic tests the cables connecting the navi-
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
move to the 6
th
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.
