Symptom Troubleshooting (cont’d)
NOTE:
 Check the vehicle battery condition first.
 Check the connectors for poor connection or loose terminals.
 Before troubleshooting, get the navigation system anti-theft code.
 After troubleshooting, enter the navigation system anti-theft code.
 Full brightness on the instrument panel brightness control with the head lights turned on causes the
system to stay in the day mode, even when the lights
are on.
1. Make sure the instrument panel brightness control is not on full brightness. Turn the headlights on and
adjust the dash brightness to the middle range.
2. Change the day/night mode under Set-up to AUTO, and recheck.
The system is OK at this time.
Go to step 3.
3. Go into the Diagnostic Menu and use the Car Status test to check for an ILL signal (see page 23-141).
Replace the navigation unit (see page 23-155).
Check the ILL circuit between the
navigation unit and the No. 14 (7.5 A) fuse in the
under-dash fuse/relay box. NOTE:
 Check the vehicle battery condition first.
 Make sure that the correct DVD color and version are installed.
 Check any official Honda service website for more service information about the navigation system.
1. Start the engine and turn the ignition switch to LOCK (0), then turn the ignition switch to ON (II).
The system is OK at this time.
Check the DVD for scratches or damage, and
the navigation unit for water damage. If OK, go into
the Diagnostic Menu and do all of the Unit Check
tests (see page 23-139). Also check for low battery
charge or poor charging system performance.

NOTE: This is often caused by a loss of battery power, a low or poor battery condition, or a poor ground.
 Make sure that the correct DVD color and version are installed.
 Check any official Honda service website for more service information about navigation system.
1. Measure the voltage between navigation unit connector A (17P) terminal No. 17 and body ground.
Go to step 2.
Repair open in the wire between the under-
dash fuse/relay box and the navigation unit. 2. Turn the ignition switch to ON (II).
3. Measure the voltage between navigation unit
connector A (17P) terminal No. 14 and body ground.
Go to step 4.

There is no PC card in the PC slot, and the screen
should display, PC card is not inserted.
If the factory provides a PC card and instructs you to
insert it, the screen displays the Manufacturer, and
Product Name as shown in the following screen. Touch
the FILES button to see the contents of the card.
This diagnostic screen checks the status of each of the
hard buttons surrounding the navigation display. When
you press each hard button, the corresponding item on
the screen should flash blue. Touch the return key, or
press and hold the joystick to exit.
NOTE: It is normal for the VOL ( , ) CH ( , ) and
MODEbuttontobeinactive. Use this screen to confirm that navigation unit is
properly receiving input signals. Signals equal to (0) are
OFF, and signals equal to (1) are ON. If the value on the
display does not match the actual vehicle status, then
check the wire carrying the signal.
 VSP-Vehicle Speed Pulse from ECM/PCM connector A (Navigation unit connector A (17P) terminal No. 13)
a) OFF (0) when vehicle is not moving
b) ON (1) when vehicle is moving
The VSP comes from the ECM/PCM as a dedicated
signal. Internally, the navigation unit compares the
actual VP on the map against street data to adjust the
pulse to speed scaling factor.
 BACK-Reverse indication from taillight relay (Navigation unit connector C (12P) terminal No. 7)
a) OFF (0) when shift lever is in any position other
than reverse
b) ON (1) when shift lever is in reverse
The Back signal is used by the navigation unit to allow
the map screen to show the VP moving backwards
when in reverse and to trigger the optional rear view
camera. This signal is needed because the Speed Pulse
does not provide any directional information to the
system.
ILLCANCEL a) OFF (0) when the dash lights brightness control
button is less than 90 % brightness with the
headlights turned on.
b) ON (1) when the dash lights brightness control
button is more than 90 % brightness with the
headlights turned on.

(XM) OFF AIR XM channel not in service. Try another XM channel.
(XM) NO SIGNAL Loss of signal. Both terrestrial and satellite antennas have lost
signal. Park the vehicle outside with a clear
view of the southern horizon.
(XM) UPDATING XM radio is receiving
information update from the
network. This message disappears once the update
finishes.
(XM) CHECK ANTENNA XM antenna error. Repair open or short in the satellite antenna.
Substitute the XM antenna with a known-good
one, and recheck. If the error is gone, replace
the original XM antenna. If the error is still
present, replace the antenna lead.
(XM) ANTENNA ERROR
No signal from XM. Check a known-good vehicle with XM radio. If
the known-good vehicle has the same
symptoms, contact XM Satellite Radio at
800-852-9696.

CODE ERROR E Anti-theft code mismatch
(10 try). Remove the No. 23 (10 A) fuse in the under-

have 10 more tries to enter the correct anti-
theft code.
NOTE: Do XM error codes checks with the vehicle parked outside with a clear view of the southern horizon.

NOTE:
 Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
1. Turn the ignition switch to ON (II).
2. Push the power switch ON to see if the navigation unit turns ON.
Intermittent failure, the system is OK at this
time.
Go to step 3.
3. Turn the ignition switch to LOCK (0).
4. Check the No. 23 (10 A) fuse in the under-hood fuse/relay box and No. 35 (7.5 A) fuse in the under-
dash fuse/relay box.
Go to step 5.
Replace the fuse(s), and recheck.
5. Remove the navigation unit (see page 23-355). Check that the navigation unit is properly
connected.
NOTE: Eject all the discs before removing the navigation unit to prevent damaging the CD player’s load
mechanism.
 Remove the PC card before removing the navigation unit.
Go to step 6.
Reconnect the connector, and recheck the
function. 6. Disconnect navigation unit connector A (24P)
7. Turn the ignition switch to ON (II).
8. Measure the voltage between body ground and
navigation unit connector A (24P) terminals No. 14
and No. 24 individually.
Go to step 9.
Repair open in the wire(s) between the No. 23
(10 A) fuse in the under-hood fuse/relay box and
the No. 35 (7.5 A) in the under-dash fuse/relay box
and the navigation unit.
9. Turn the ignition switch to LOCK (0).
10. Reconnect navigation unit connector A (24P).
