General Troubleshooting Information
Refer to the Navigation System manual for the
navigation system operating procedures.
The navigation system has a coded theft protection
circuit. Be sure you have the client’s anti-theft security
code before;
 Disconnecting the battery
 Disconnecting the navigation unit A (17P) and C (12P) connector
 Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box
After service, reconnect power to the navigation unit,
and turn the ignition switch ON (II). Enter the 4-digit
anti-theft security codes, then select Done.
If the code cannot be found, use the interactive Network
(iN) to look it up. You can view the serial number in one
of the Navi ECU diagnostic screen (see page 23-139).
Alternatively, you can find the serial number from the
navigation unit in the dash.
When replacing the navigation unit, be sure to give the
client the new anti-theft security code.
Certain circumstances and system limitations can result
in occasional vehicle positioning errors. Some clients
may think this indicates a problem with the navigation
system when, in fact, the system is normal. Keep the
following items in mind when interviewing clients
about symptoms of the navigation system. The limitations of the self-inertial portion of the
navigation system (the yaw rate sensor and the vehicle
speed signal) can cause some discrepancies between
the vehicle’s actual position and the indicated vehicle
position (GPS vehicle position).
The following circumstances may cause vehicle
positioning errors:
 Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if
the vehicle is spun on a turn table.
 Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in
travel distances. Examples of this include:
– Continuous tire slippage on a slippery surface.
– Driving with snow chains mounted.
– Abnormal tire pressure.
– Incorrect tire size.
– Frequent lane changes across a wide highway.
– Continuous driving on a straight or gently curving highway.
 Tolerances in the system and map inaccuracies will sometimes limit how precisely the vehicle position is
indicated. Examples of this include:
– Driving on roads not shown on the map (map matching is not possible).
– Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking
garage.
– Driving on a road with a series of sharp hair-pin turns.
– Driving near a gradual highway exit or transition.
– Driving on one of two close parallel roads.
– Making many 90 degree turns.
– The direction to destination icon or the destination icon shown or the map may be up to several
hundred feet away from the actual location.

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.
 Check the connectors for poor connections or loose terminals.
 Before troubleshooting, make sure you have the navigation system anti-theft code.
1. 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, and reinstall the fuse if it is OK.
Go to step 2.
Replace the fuse and recheck.
2. Turn the ignition switch to ON (II).
3. Operate the radio and listen to the audio.
Go to step 4.
Refer to audio system troubleshooting.
4. Turn the ignition switch to LOCK (0).
5. Remove the navigation unit (see page 23-155). 6. Measure the voltage between navigation unit
connector A (17P) terminal No. 17 and body ground.
Go to step 7.
Repair open in the wire between the under-
dash fuse/relay box and the navigation unit.
7. Turn the ignition switch to ON (II).
8. Measure the voltage between navigation unit connector A (17P) terminal No. 14 and body ground.
Go to step 9.

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.
