7. Check for continuity between navigation unit

connector D (12P) terminal No. 1 and HFL-voice
control switch 5P connector terminal No. 2.

Go to step 8.

Repair open in the wire between the

navigation unit and the HFL-voice control switch, or
replace the cable reel.

8. Disconnect navigation unit connector A (24P).

9. Check for continuity between navigation unit

connector A (24P) terminal No. 5 and HFL-voice
control switch 5P connector terminal No. 4.

Replace the navigation unit (see page 23-355).

Repair open in the wire between navigation

unit and voice control switch, or replace the cable
reel.

10. Use the Mic Level diagnostic under Functional

Setup (see page 23-309) to check the operation of
the microphone.

Check the operation of the voice control

system (see the Navigation System Manual).

Go to step 11.

11. Check the HFL DTCs (see page 23-360).

Repair the indicated DTCs.

Substitute a known-good HFL-navigation

microphone (see page 23-358), then reconnect all
of the connectors and recheck. If the symptom/
indication goes away, replace the original
microphone. If the symptom/indication is still
present, replace the navigation unit (see page
23-355).

Navigation System

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. Go to step 4.

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 the yaw r ate sensor and vehicle speed pulse
OK ?

Does the pr oblem occur in the same place?

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
the same place.

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?

Is the yaw r ate sensor OK ?

Ar e the vehicle speed pulse and the BACK signals
OK ?

Does the pr oblem occur in the same place?
