NAVIGATION UNIT CONNECTOR A (17P) ILL (GRY)NOTE: Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
1. Turn the ignition switch to ON (II).
2. Turn the combination lighting switch to the parking light position.
3. Check the illumination of the navigation unit buttons.
Intermittent problem: the navigation unit is
OK at this time. Check for loose or poor
connections at navigation unit connector A (17P).
Go to step 4.
4. Check the illumination of several other buttons not related to the navigation system.
Go to step 5.
Troubleshoot the interior lights. Start by
checking the No. 14 (7.5 A) fuse in the under-dash
fuse/relay box. If the fuse is OK, check for an open
in the wire between the under-dash fuse/relay box
and the navigation unit.
5. Turn the ignition switch to LOCK (0).
6. Disconnect navigation unit connector A (17P). 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.
7. Disconnect gauge control module (tach) 36P connector. 8. Check for continuity between navigation unit
connector A (17P) terminal No. 1 and gauge control
module (tach) 36P connector terminal No. 14.
Go to step 9.
Repair open in the wire between the gauge
control module and the navigation unit.
9. Turn the ignition switch to ON (II).
10. With the headlight switch still on, measure the voltage between navigation unit connector A (17P)
terminal No. 10 and body ground.
Check the connections at navigation unit
connector A (17P). If all connections are OK, replace
the navigation unit (see page 23-155).
Repair open in the wire between the under-
dash fuse/relay box and the navigation unit.

PC card will not play/card icon on audio
screen cannot be selected (with navigation)
23-67
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 customer 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.
