NOTE: If only the XM stations are lost, go to XM radio
preset memory is lost (see page 23-71).
1. Set each of the radio station preset buttons.
Go to step 2.
 With navigation: Replace the navigation unit (see page 23-155).
 Without navigation: Replace the audio unit (see page 23-80).
2. Turn the ignition switch to LOCK (0) for 1 minute, then turn it back to ON (II).
3. Test the preset buttons for proper recall operation.
System is normal at this time. Check the
connections at the navigation unit or audio unit.
 With navigation: Replace the navigation unit (see page 23-155).
 Without navigation: Replace the audio unit (see page 23-80). NOTE:
 Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
 Set the fader and balance positions to the center.
1. Listen for sound from the speakers.
Go to step 2.
Go to audio system sound is weak or
distorted, or no sound is heard from speaker(s)
(see page 23-39).
2. Operate the volume knob to see if the volume changes.
Operation is normal.
 With navigation: Replace the navigation unit (see page 23-155).
 Without navigation: Replace the audio unit (see page 23-80).

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)

Special Tools Required
Electrical Noise Test
23-75
Diagnostics CD 07AAZ-SDBA100
Do this test to check for electrical noise being induced
into the audio system.
NOTE: Electrical noise may be caused by outside
sources that cannot be handled by the audio system.
Make sure you remove any cell phones and/or turn off
any aftermarket device before beginning this test.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 4 (digital zero) at a normal, or slightly higher than normal, volume level.
3. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
4. Play track No. 5 (near digital zero) at a normal, or slightly higher than normal, volume level.
5. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
6. Play track No. 6 (SNR) at a normal, or slightly higher than normal, volume level. 7. Operate any electrical device that may create
electrical noise in the audio system, including
starting the engine.
 If no abnormal noise is heard, go to individual speaker test.
 If the noise is present only during the SNR track, replace the navigation unit or audio unit.
 If the noise is heard during the digital zero or near digital zero track, check for;
– Poor ground for the audio unit, amplifier, engine or battery cable
– Pinched or shorted speaker or amplifier wire
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit
– Other faulty components causing excessive electrical noise (ignition coils, alternator, door
lock actuators, etc.). Disconnect any suspect
components, and then replay the tracks that
were originally noisy. If the noise is gone,
check the component’s circuit and the
component.
