WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
Do this test to check the performance of the audio system's AM and FM reception. Refer to AUDIO SYSTEM SOUND WEAK OR DISTORTED, WITH NAVIGATION , WITHOUT NAVIGATION , or NO SOUND IS HEARD FROM THE SPEAKERS (DISPLAY IS NORMAL), WITH NAVIGATION , WITHOUT NAVIGATION 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 system to receive radio signals.
- Park the client's vehicle in an open area away from buildings or other obstructions.
- Park a known-good vehicle (same year, model, and trim level) next to the client's vehicle, facing the same direction.
- Start the engine in the client's vehicle, and turn on the radio.
- Set the FM receiver to 87.7 MHz.
- Press the Seek + button, and record the first station that the audio unit or audio-navigation unit locks onto.
- Press the Seek + button repeatedly, and write down each station that the audio unit or audio-navigation unit locks onto until the station recorded in step 5 is reached again.
- Set the AM receiver to 530 kHz.
- Press the Seek + button, and record the first station that the audio unit locks onto.
- Press the Seek + button repeatedly, and write down each station that the audio unit or audio-navigation unit locks onto until the station recorded in step 8 is reached again.
- Turn the ignition switch to LOCK (0).
- Start the engine in the known-good vehicle, and then do steps 4 thru 10 on the known-good vehicle.
- 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 or audio-navigation 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 poor AM or FM radio reception or interference.
- with navigation (see POOR AM OR FM RADIO RECEPTION OR INTERFERENCE (WITH NAVIGATION) )
- without navigation (see POOR AM OR FM RADIO RECEPTION OR INTERFERENCE (WITHOUT NAVIGATION) )
