NOTE: Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
1. Verify the SVC mode setting in the navigation unit sound set-up.
Change the setting to Mid and retest
(see page 23-164).
Go to step 2.
2. Do the self-diagnostic function for the vehicle speed pulse indication (see page 23-190).
Substitute a known-good navigation unit
(see page 23-355), and retest. If the symptom/
indication goes away, replace the original
navigation unit.
Go to step 3.
3. Test-drive the vehicle at highway speeds, and monitor if the volume increases.
Intermittent failure, the system is OK at this
time.
Go to step 4. 4. Remove the navigation unit (see page 23-355) and
disconnect navigation unit connector A (24P).
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.
5. Drive the vehicle, and have an assistant measure voltage at navigation unit connector A (24P)
terminal No. 15.
Replace the navigation unit (see page 23-355).
Repair open or shorts in the wire between
navigation unit connector A (24P) terminal No. 15
and ECM/PCM connector A (44P) terminal No. 29. If
no opens or shorts are found, 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).

23-234Audio System
Symptom Troubleshooting (cont’d)
Unfortunately there are no error messages, and no
diagnostics for the PC card. There are many reasons
why a card won’t play audio files in the audio unit.
 The card may not be fully inserted into the slot. Eject the card, and inspect for warping or damage to the
edge connector. N ever use excessive force to insert a
card. This can result in damage to the pins in the rear
of the slot.
 The client’s card may contain audio files that are not recognized by the system. Only MP3, and WMA
music files are played.
 The flash card type may not be accepted by the system. Only Compact Flash and ATA cards have
been tested.
 The card’s PCMCIA adaptor may be preventing a known-good card from playing. New PCMCIA
adaptors are constantly being released, and have not
been tested.
 The card’s capacity may exceed 1 GB. Only cards with capacities of up to 1 GB (1000 MB) have been
tested.
 There may not be any files on the card. Some cards have write protection, make sure it is turned off
before putting files on the card.
 Although flash memory chips are reliable, occasionally they develop bad sectors or other
formatting errors that prevents them from playing.
The client should re-format the card using the FAT, or
FAT32 format.  The card may have been damaged by heat. Suggest
that the client remove their card when exiting the
vehicle.
 The client may have formatted the card using the format NTFS. Only the formats FAT, and FAT32 are
accepted by the system.
 Hard Disc Drive (HDD) cards may not work properly in the system and can overheat and quit functioning,
particularly in a hot vehicle. They are not
recommended.
 The filing structure of the card may exceed the specification of 8 folder levels deep, 99 folders
maximum, and 999 total tracks maximum. If any of
these limitations is exceeded, the system may not
properly display or play the tracks.
NOTE: A delay when first inserting a card is normal.
The system is reading the File Tag information for
album names, artist, and song titles and there is no
hour glass, The delay length depends on the number of
tracks, and the complexity of the folder structure.
See the audio section glossary for an explanation of the
terms used above.

10. Turn the ignition switch to LOCK (0).
11. Start the engine in the known-good vehicle, and
then do steps 4 thru 10 on the known-good vehicle.
12. Compare the number of stations received in steps 6 and 9 in the client’s vehicle with the number of
stations received in the known-good vehicle.
 If the number of stations received is the same, or within 10 %, the audio unit’s tuner performance
is OK. The problem may be atmospheric
conditions, multi path interference, or other
obstructions to the radio signal.
 If the customer’s vehicle receives fewer stations by at least 10 %, go to step 2 of poor AM or FM
radio reception of interference, with navigation
(see page 23-196), wit hout navigation (see page
23-199). SRS components are located in this area. Review the
SRS component location (see page 24-11).
Also review the precautions and procedures (see page
24-13) in the SRS section before doing repairs or
service.
NOTE:
 Put on gloves to protect your hands.
 Take care not to scratch the dashboard and related parts.
 Lay a workshop towel under the parts when working on them to protect the face panel from scratches or
other damage.
 Do not work in a dusty or dirty place.
 Discharge static electricity from your body before and during the work.
 Do not touch the circuit board(s) with your bare hands.
 Do not work with dirty hands.
 Be careful not to fold the flat plate cable.
 Do not touch the terminal connector of the flat plate cable with your bare hands (If you have touched it,
wipe it off thoroughly.).
 Eject all the discs before removing the audio unit to prevent damaging the CD/DVD player’s load
mechanism.
 If you are replacing the audio unit, write down the audio presets (if possible), and enter them into the
new audio unit.

(Individual Diagnostic screens to confirma specific diagnostic screen.)
NOTE: If the vehicle left the factory in the factory
diagnostic mode, or if the navigation unit is replaced
you will see this screen every time you turn on the
ignition.
When a navigation unit is powered up for the first time
at the factory or after replacement with a new or
remanufactured navigation unit, the factory diagnosis
screen (In Line Diag) appears. Normally the factory
does the steps necessary to verify proper operation and
terminate the factory diagnostic.
Until the proper confirmation sequence is done, the
screen appears every time the vehicle is started.
Follow the steps below to prevent the screen from
showingupinthefuture:
 Press and hold the buttons (MENU, MAP/GUIDE, and CANCEL) for about 3 seconds. The Select Diagnosis
items screen appears.
 Press and hold the MAP/GUIDE button for 5 10 seconds. A screen with a Complete button,
appears.
 Press complete, then Return, and then shut the key off for 5 seconds. Do not disconnect the battery
during this period as the unit is saving the setting to
the SRAM memory. The In Line Diag should not
appear again.
 Restart the vehicle, and confirm normal operation by completing the TQI of the Navigation System Service
Bulletin. These section allows you to run a specific diagnostic
and allows additional setting choices for some screens
that are not shown when selecting an icon from the
System Links screen.
When you select the menu item Detail Information &
Setting menu, the main diagnosis menu is displayed.

This screen is for factory use only, and should always
be set to OFF. Occasionally the DEMO setting is turned
ON when vehicles are being used at Auto Shows or
similar events. Turning this feature on, allows the
navigation system to automatically follow a route to a
destination when the vehicle is stationary. The Speed
changes the speed of the demo mode. This diagnostic allows you to independently test the
microphone and the navigation TALK and BACK
buttons. They are used to activate the voice control
system. The microphone is located near the map light
in the roof console. It is directional, and works only with
the voice coming from the driver’s seat.
 Press the navigation TALK button on the steering wheel, wait unit you hear a beep, and in a normal
voice say ‘‘testing’’. The TALK indicator on the screen
should momentarily turn green, and the text Now
Recording... should appear in yellow. If the talk
indicator shown on the screen does not briefly turn
green, check the wiring from the steering wheel
navigation TALK button to the navigation unit. If there
is no Mic Level movement when you speak, then you
should check the wires running from the microphone
in the roof console to the HandsFreeLink control unit
and the navigation unit. If the wires are OK, the
microphone must be faulty; replace the microphone
located in roof console (see page 23-358).
 PressthenavigationBACKbuttononthesteering wheel. This should cause the Cancel indicator on the
