Self-diagnostic Function
A
The audio system has a self-diagnostic function.
To obtain the audio unit serial number on a vehicle, do the following:
NOTE: This procedure can only be performed when the battery power is disconnected from the audio unit and the audio unit displays CODE.
 To obtain the navigation unit serial number, refer to Navi ECU in the navigation system diagnostic mode (see page 23-135).
1. Turn the ignition switch to ON (II).
2. Make sure the audio system is turned off.
3. Push and hold the preset No. 1 and No. 6 buttons.
4. While holding the buttons, push the VOL PUSH PWR knob (A) to ON.
5. Release the buttons and the self-diagnostic begins.
6. The display shows a 8 digit serial number.
7. Use all 8 numbers as the serial number when using the Interactive Network (iN) to retrieve the 5 digit anti-theft code.
8. To end the self-diagnostic function, turn the audio unit off, or turn the ignition switch to LOCK (0).

Error Codes
The audio system displays error codes when a problem is detected with the disc changer, the disc, the XM radio, or
the anti-theft code.
This is not a complete list of audio error codes. Refer to symptom troubleshooting, or go to any official Honda service
website for more service information.
DISC ERROR The system cannot read the disc because an audio or video DVD
is inserted into the unit. The CD
may be inserted upside down.Verify that the unit functions with a standard
mass production CD.
MECH ERROR There is a problem with the mechanism A CD label may be
jammed in the mechanism.Replace the navigation unit.




BAD DISC-PLEASE CHECK
OWNERS MANUAL PUSH
EJECT
CDlabeljammedinthe
mechanism.
CD eject mechanism or motor
is inoperative.
CD spindle motor won’t spin
up the CD.
The wrong type disc is
inserted.Press the EJECT button and hold it for 5
seconds. If the disc does not eject, try again.
If the disc still won’t eject, replace the unit.




HEAT ERROR CD player is too hot. This can
happen if the vehicle is parked
in the sunlight all day.The unit should function normally when it
cools off.
FORMAT Audio unit cannot read the files on the CD or CD-R.Current track is skipped. The next supported
track or file plays automatically.
Verify that CD, CD-R or CD-RW file names
endinCD-AorWMA.
Verify that CD, CD-R or CD-RW with
compressed music formats end in MP3 or
WMA.
Other file formats like I-tunes or Ogg are
not recognized.
WMA files may have (DRM) copy
protection and cannot be read.

NOTE:
 Check the vehicle battery condition first.
 Check for aftermarket accessories plugged into the vehicle accessory power sockets (including cell
phone).
 Check the connectors for poor connections or loose terminals.
 Check the radio reception in an open area. Compare it to a known-good vehicle when ever possible.Poor
reception/interference can be caused by the
following:
– The radio station is far away.
– Atmospheric conditions are unfavorable.
– Tall buildings, mountains, or high-voltage power lines are nearby.
– Aftermarket metallic wi ndow tint.
1. Turn the ignition switch to ON (II).
2. Do the seek stop test (see page 23-78).
Multipath interference or weak station.
Operation is normal. Go to step 3.
3. Check if the radio reception/interference is the same in several locations.
Go to step 4.
Multipath interference or weak station.
Operation is normal.
4. Start the engine.
5. Check the reception/interference.
Check the antenna and radio grounds. If OK,
check the charging system and the ignition
system. Go to step 6.
6. Turn the ignition switch to LOCK (0). 7. Remove the right side C-pillar trim (see page 20-75).
8. Check the connections from the AM/FM antenna
amplifier to the window antenna.
Repair the connections, or substitute a
known-good AM/FM antenna amplifier and retest.
If the symptom/condition goes away, replace the
original AM/FM antenna amplifier (see page 23-87).
Go to step 9.
9. With the help of an assistant inside the vehicle, have the assistant shine a flashlight (A) along each
antenna wire (B). Check from the outside of the
vehicle for any breaks or openings in the antenna
wires (the light shines through).
Repair the window antenna. Go to AM/FM
antenna repair (see page 23-87), or replace the rear
window (see page 20-47).
Go to step 10.

antenna amplifier and body ground.
Go to step 19.
Go to step 15.
15. Turn the ignition switch to LOCK (0).
16. Disconnect navigation unit connector G (3P). 17. Check for continuity between the AM/FM antenna
amplifier 3P connector terminal No. 3 and body
ground.
Repair short to body ground in the wire
between the navigation unit and the AM/FM
antenna amplifier.
Go to step 18.
18. Check for continuity between navigation unit connector G (3P) terminal No. 3 and the AM/FM
antenna amplifier 3P connector terminal No. 3.
Substitute a known-good navigation unit
(see page 23-155), and recheck.
Repair open in the wire between the
navigation unit and the AM/FM antenna
amplifier.
