8. Compare the client’s vehicle’s sound quality results to 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 (Type S model)
– Damaged speaker(s)
– Faulty amplifier
– 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 23-206) 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, 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.
