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.

NOTE:
 Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
1. Try loading a known-good disc.
Go to step 2.
Go to audio disc does not load (see page
23-61).
2. Insert the audio diagnostic CD (T/N: 07AAZ- SDBA100) in the navigation unit or audio unit.
The original disc is faulty, or has an
unreadable format.
 With navigation: Replace the navigation unit (see page 23-155).
 Without navigation: Replace the audio unit (see page 23-80).  Diagnostics CD 07AAZ-SDBA100

1. Confirm the vehicles tires are properly inflated.
2. Check the clients CD for scratches, fingerprints, and marks.
NOTE: Do this following test with audio unit bass
and treble set to clients listening performance.
When comparing to known-good vehicles,
comparison should be performed on same model
and trim level.
3. Test drive to identify when the CD skips. The diagnostics CD (T/N: 07AAZ-SDBA100) can be used
if clients CD is not available. Use tracks 10 to 12.
Go to step 4.
Operation is normal.
4. Compare the clients CD that skips in a known-good vehicle under the same conditions.

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.

Seek Stop Test
23-7823-78 Audio System
Sound Quality Diagnosis (cont’d)
8. Compare the client’s vehicle’s sound quality results
to the known-good vehicle’s results.
 If the sound quality in the customer’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 (Type S model)
– Damaged speaker(s)
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit Do this test to check the performance of the audio unit’s
AM and FM reception. Refer to symptom
troubleshooting: audio sound weak or distorted, or no
sound is heard from speakers (display is normal)
(see page 23-39) before continuing with this test.
NOTE:
 Window tint, aftermarket theft-recovery devices and other aftermarket accessories may reduce radio
reception.
 Changes in cloud cover and other atmosphere conditions will affect the ab ility of the navigation unit
or audio unit to receive radio signals.
1. Park the client’s vehicle in an open area away from buildings or other obstructions.
2. Park a known-good vehicle (same year, model, and trim level) next to the client’s vehicle, facing the
same direction.
3. Start the engine in the client’s vehicle, and turn on the radio.
4. Set the FM receiver to 87.7 MHz.
5. Press the Seek button and record the first station that the navigation unit or audio unit locks onto.
6. Press the Seek button repeatedly, and write down each station that the navigation unit or audio
unit locks onto until the station recorded in step 5 is
reached again.
7. Set the AM receiver to 530 kHz.
8. Press the Seek button, and record the first station that the navigation unit or audio unit locks
on to.
9. Press the Seek button repeatedly, and write down each station that the navigation unit or audio
unit locks onto until the station recorded in step 8 is
reached again.

10. Turn the ignition switch to LOCK (0).
11. Start the engine in the known-good vehicle, andthen perform 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 client’s vehicle receives fewer stations by at least 10 %, go to step 2 of poor AM or FM radio
reception of interference (see page 23-29).
