Symptom Troubleshooting (cont’d)
NOTE:
 Check the vehicle battery condition first.
 Check that the GPS antenna is plugged in.
 This is not the same condition as when driving off- road (or on a fire or logging road). This condition is
caused by a loss of map matching from a bad sensor
input. Check for after market window tinting or other
objects that can block the GPS signal. Always do the
Map matching (see page 23-269) before proceeding
with the troubleshooting.
 Make sure that the correct DVD color and version are installed.
 Inspect the DVD for dirt or damage.
 Check any official Honda service website for more service information about the navigation system.
 Check the GPS signal reception in an open area.
1. Check the GPS icon on the navigation screen.
Do the troubleshooting for GPS icon is white
or not shown (see page 23-341).
Go to step 2. 2. Go into the Self-Diagnosis Mode, and use the Yaw
Rate test (see page 23-314) to check the yaw rate
sensor.
3. Go into the Self-Diagnosis Mode, and use the Car Status test (see page 23-315) to check the vehicle
speed pulse.
The condition may be normal. Check to see if
the condition occurs in the same place in a known-
good vehicle. If it does, the problem could be in the
database.Gotostep4.
If the problem is the yaw rate sensor, replace
the navigation unit (see page 23-355). If the
problem is the vehicle speed pulse, check for an
open in the wire between the navigation unit and
the ECM/PCM (VSP signal). If the wire is OK,
substitute a known-good navigation unit, and retest.
If the problem goes away, replace the original
navigation unit. If the problem is still present,
replace the ECM/PCM.
4. Substitute a known-good navigation unit, and check to see if the problem occurs in the same
place.
The problem is in the database. Report the
problem according to the Navigation System
Manual under Reporting Errors.
Replace the original navigation unit (see page
23-355).
Is the GPS icon white? Ar e t he y aw r at e sensor and v ehi cl e speed pul se

NOTE:
 Check the vehicle battery condition first.
 This is not the same condition as when driving off-road (or on a fire or logging road).
 This condition is caused by a loss of map matching from a bad sensor input. Check for aftermarket or
other objects that can block the GPS signal. Always
perform Map matching (see page 23-269) before
proceeding with the troubleshooting.
 Always check for and resolve all CAN DTCs before troubleshooting the navigation system.
 Verify that the correct navigation unit is installed for this model. Go into the Diagnostic mode, and use
Version (see page 23-316).
 Make sure that the correct DVD color and version are installed.
 Check for aftermarket metallic window tinting.
 Inspect the DVD for dirt or damage.
 Check any official Honda service website for more service information about the navigation system.
 Before troubleshooting, make sure you have anti- theft codes for the navigation system.
 After troubleshooting, enter the anti-theft codes for the navigation system.
 Check the DVD for damage or scratches.
 Check for connectors for poor connections or loose terminals.
1. Check the GPS icon on the navigation screen.
Do the troubleshooting for GPS icon is white
or not shown (see page 23-341).
Go to step 2.
2. Go into the Self-Diagnostic mode, and use the Yaw Rate diagnosis (see page 23- 314) to check the yaw
rate sensor.
Go to step 3.
Replace the navigation unit (see page 23-355). 3. Go into the Diagnostic mode, and use the Car
Status diagnosis (see page 23-315) to check the
vehicle speed pulse (VSP) and the BACK signals.
The problem may be a characteristic of the
system. Check to see if the problem occurs in the
same place in a known-good vehicle. If it does, the
problem could be in the database. Go to step 4.
 If the problem is the vehicle speed pulse, troubleshoot the vehicle speed signal circuit. BLU
wire for open or short. If OK, good ECM/PCM. If
the problem or symptom goes Update the ECM/
PCM (see page 11-227) if it does not have the
latest software or substitute a known-good ECM/
PCM (see page 11-228).
 If the BACK signal is indicated ON (I), when in any shift lever position other than reverse,
troubleshoot the back-up light switch circuit or
MICU (A/T).
4. Substitute a known-good navigation unit (see page 23-355), and check to see if the problem occurs in
thesameplace.
The problem is in the database and should
be considered a characteristic of the system.
Report the problem according to the Navigation
System Owner’s Manual under Reporting Errors
and look for improvements in future databases.
Replace the navigation unit (see page 23-355).
Is the GPS icon white or missing?

 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 23-315).
Replace the navigation unit (see page 23-355).
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 23-305). Also check for low battery
charge or poor charging system performance.

 After troubleshooting, re-enter the anti-theft code, and re-initialize the navigation system, then enter the
audio presets.
 Check for aftermarket accessories that use the same power circuit. A feedback can cause this problem.
1. Remove the key from the ignition.
Go to step 2.
The system is OK at this time.
2. The vehicle may have been used as a demonstration vehicle at an event like an auto
show. In these events, power is often jumpered to
the navigation system so that the ignition key is not
needed in the vehicle. At the end of the show, the
jumper wire may not have been removed. Check
the navigation unit connector A (24P) for a non-
factory jumper wire in series with the factory cable.
Remove the jumper wire, and re-test. Return
the jumper wire to Tech Line.
Go to step 3.
3. Check if the audio unit works.
Troubleshoot the ACC circuit for a short to
power with another circuit.
Replace the navigation unit (see page 23-355). NOTE:
 Check the vehicle battery condition first.

(After 10 consecutive tries, you must cycle the key to
continue trying)
 The Navigation System Diagnosis and Core Return From is available online, under Job aids, and can be
printed out for recording this information. This
information will help the reman facility determine
what caused the failure.
 Check the connectors for poor connections or loose terminals.
 Before troubleshooting, make sure you have the anti- theft codes for the navigation system.
 Verify that the correct navigation unit is installed for this model. Go into the Diagnostic mode, and use
Version (see page 23-316).
 Make sure that the correct navigation DVD color and version are installed.
 Check any official Honda service website for more service information about the navigation system.

brief diagnostic runs for 20 seconds, and the serial
number is displayed.
Go to step 4.
Go to step 2.
2. Remove the navigation unit (see page 23-355).
3. Check the serial number on the label on the underside of the navigation unit.
Go to step 4.
Replace the navigation unit (see page 23-355). 4. Using the serial number, look up the navigation
security code in the Interactive Network. (click:
Service, Vehicle Information, Anti-Theft code
Inquiry, and then select Navigation from the
Product dropdown box). Enter the serial number.
Go to step 5.
Call the Warranty Department to obtain the
code (the telephone number is in the PDI service
bulletin).Thengotostep5.
5. Check that the obtained code works to bypass the code screen in the navigation system.
The system is OK at this time Return the
vehicle to the client, and give them the anti-theft
code.
Go to step 6.
6. Try entering four zeros (0000) in place for the code.
Replace the navigation unit, and enter
Security code is 0000 in the problem description
field of the core return form.
