Note. Disc labels should not be used in the audio unit. They may damage the player mechanism. Make sure the CD disc is compatible with the system (refer to the owner's manual for more information).

1. Insert a known-good disc to see if the symptom can be duplicated. Does the disc load? YES - Operation is normal. If the disc loads normally. But will not play, go to disc does not play (see AUDIO DISC DOES NOT PLAY ). NO - Go to step 2.
2. Insert another disc. Does the disc load? YES - The original disc is faulty. NO - With navigation: Replace the CD changer. Without navigation: Replace the audio unit.

Audio disc skips

1. Confirm the vehicle tires are properly inflated.
2. Check the customer's CD for scratches, fingerprints, and marks. NOTE: The following test should be performed with audio unit bass and treble set to customer's listening performance. When comparing to a known-good vehicle, comparison should be performed on same model and trim level.
3. Test drive to identify when the customer's CD skipping occurs. The audio diagnostic CD (T/N: 07AAZ-SDBA100) can be used if the customer's CD is not available. Use tracks 10-12. Does the skipping occur? YES - Go to step 4. NO - Operation is normal.
4. Compare the customer's CD that is skipping to a known-good vehicle under the same conditions. Does the CD skip in the known-good vehicle under the same conditions? YES - Operation is normal. NO - Go to step 5. NOTE: The following test should be performed with the vehicle parked and engine running.
5. Insert the diagnostic skip test CD (07AAZ-SDBA300) (ABEX TCD 721). Play tracks 2-11 and note the track number(s) the CD starts skipping. Do the same test on a known-good vehicle. Does the CD skip on same track(s) number as the known-good vehicle? YES - Operation is normal. NO - Go to step 6.
6. Insert the diagnostic skip test CD (07AAZ-SDBA200) (ABEX TCD 725B) play tracks 7-11 and tracks 13-15 and note the track number(s) the CD starts skipping. Perform the same test on a known-good vehicle. Does the CD skip on same track(s) number as the known-good vehicle? YES - Operation is normal. NO - With navigation: Replace the CD changer. Without navigation: Replace the audio unit.

Scheme 67

1. Test the radio remote switch (see RADIO REMOTE SWITCH TEST ). Is the radio remote switch OK? YES - Go to step 2. NO - Replace the radio remote switch.
2. Check the audio unit operation (volume up, volume down, CH (-), CH (+), MODE). Is the audio unit operation OK? YES - Go to step 3. NO - Replace the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ), and recheck.
3. Remove the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ).
4. Measure resistance between the audio unit connector (20P) A3 and A11 terminals as specified in the table shown in AUDIO UNIT CONNECTOR (20P) A3 AND A11 . AUDIO UNIT CONNECTOR (20P) A3 AND A11 Button held down VOL DOWN VOL UP CH (-) CH (+) MODE (NONE) Resistance about 100 ohm about 370 ohm about 770 ohm about 1.7 Kohm about 3.7 Kohm 10 k ohm Is resistance OK? YES - Go to step 5. NO - Repair open or high resistance in the circuit between the audio unit and the radio remote switch. If the wires are OK, replace the cable reel (see CABLE REEL REPLACEMENT ).
5. Check for continuity between the No. 3 and No. 11 terminals of the audio unit connector A (20P) and body ground. Is there continuity? YES - Repair the short to body ground in the circuit between the audio unit and the radio remote switch. If the wires are OK, replace the cable reel (see CABLE REEL REPLACEMENT ). NO - Replace the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ).

Radio displays error code: XM NO SIGNAL or XM ANTENNA

Note. Check the XM radio reception in an open area. Poor reception/interference can be caused by tall buildings, mountains, or high-voltage power lines.

1. Park the vehicle outside with a clear view of the southern horizon. Does the XM radio receive a signal? YES - Reception interference operation is normal. NO - Go to step 2.
2. Check XM antenna connector B (2P) at XM receiver. Is XM antenna connector B connected? YES - Go to step 3. NO - Reconnect XM connector B, recheck the XM radio operation. If the signal is restored, operation is normal. If signal not restored go to step 3.
3. Substitute a known-good XM antenna. Does the XM radio receiver a signal? YES - Replace the XM antenna. NO - Substitute a known-good XM antenna subharness. If the XM radio receives signal, replace the original XM antenna subharness.

Left/Right Channel ID

Do this test to confirm proper channel routing.

1. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the CD player.
2. Play the track No. 1 (left, both, right channel ID) at a normal, or slightly higher than normal, volume level.
3. The voice should be audible only from the channel or channels when indicated. If the channel ID is correct for each side, go to PHASE TEST . If the channel ID is not correct, check for - Shorted speaker wire - Faulty amplifier - Faulty audio unit

Frequency sweep

Do this test to find rattles or reverberation that may cause a perception of poor sound quality.

1. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the CD player.
2. Play the track No. 13 (sweep from 500 Hz to 35 Hz) at a normal, or slightly higher than normal, volume level.
3. Listen to each speaker for poor sound quality or reverberations caused by specific frequencies. Use the voice-over to estimate the frequency that causes the vibration. Use the audio unit's fader and balance settings to help isolate the channel with the problem. If vibrations or poor sound quality is heard, go to step 4. If no vibrations or poor sound quality is heard, go to SOUND JUDGING .
4. Choose the appropriate track from No. 14 to 25 (small range frequency sweep) or 26 to 53 (single frequencies) to recreate the frequency that caused the poor sound quality or vibration located in step 3 : this aids in diagnosis of the cause. NOTE: When you get to the track that recreates the problem, select the repeat function on the audio unit, this will help you isolate the cause.
5. Replace or insulate the source of the vibration or, if the speaker is the source of the poor sound quality, replace it.

Sound judging

Do this test to compare overall sound quality, imaging, and dynamics between the client's vehicle and a known-good vehicle. Only use a vehicle of the same model and trim level for this test.

1. In the client's vehicle, set the bass, treble, fader, and balance settings to the client's normal settings that were written down before beginning testing.
2. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the CD player.
3. Play the tracks No. 7 to 12 (sound quality, midland, dynamics, and imaging demonstration tracks) at a normal, or slightly higher than normal, volume level. Write down the volume setting being used.
4. Listen to areas of the track that stand out as being either real clear or poorer than other areas of the track.
5. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the CD player of a known-good vehicle.
6. Play the tracks at the same volume level and the same bass, treble, balance, and fader settings as used in step 3 in the client's vehicle.
7. Listen to the same area of the track that stood out as being either real clear or poorer than other areas of the track.
8. Compare the client's vehicle's sound quality results with the known-good vehicle's results. If the sound quality in the client's vehicle is comparable to the sound quality in the known-good vehicle, then the client's vehicle is operating as designed. If the sound quality is not comparable, check these items in order. - Loose or improperly installed speakers or other hardware that may become excited by the vibrations generated by the speakers - Poor power or ground to the stereo amplifier - Damaged speaker(s) - Faulty amplifier - Faulty audio unit

Window Antenna Repair

Note. To make an effective repair, the broken section must be no longer than one inch.

Scheme 68

Scheme 69

1. Lightly rub the area around the broken section (A) with fine steel wool, then clean it with alcohol.
2. Carefully mask above and below the broken portion of the window antenna wire (B) with cellophane tape (C).
3. Mix the silver conductive paint thoroughly. Using a small brush, apply a heavy coat of paint (A) extending about 1/8" on both sides of the break. Allow 30 minutes to dry.
4. Check for continuity in the repaired wire.
5. Apply a second coat of paint in the same way. Let it dry 3 hours before removing the tape.
