Seek Stop Test

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 speaker(s) (display is normal) (see NO SOUND IS HEARD FROM SPEAKER(S) (DISPLAY IS NORMAL) ) before continuing with this test.

Note. Window tint, aftermarket theft-recovery devices and other aftermarket devices may affect reception. Changes in cloud cover and other atmospheric conditions will affect the ability of the 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 audio unit locks onto.
  6. Press the "Seek +" button repeatedly, and write down each station that the 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 audio unit locks onto.
  9. Press the "Seek +" button repeatedly, and write down each station that the 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 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 radio reception or interference (see «POOR AM OR FM RADIO RECEPTION OR INTERFERENCE»(/acura/rl/ii-2004-2008/remont/entertainment-systems/#audio-system__poor-am-or-fm-radio-reception) ).
