Reception Level Indication Mode

NOTE: This diagnostic screen checks the AM/FM reception level in the electric field strength (dB?V). This level then can be used in the diagnosis of audio unit reception quality.

Preparation:

	Park the vehicle outside in a good location away from tall buildings, mountains, high-voltage power line or any other object that may interfere with reception.
	Tune to a powerful local FM radio station then write down the radio station number.
	Tune to a powerful local AM radio station then write down the radio station number.

1.	Enter the Reception Level Indication Mode in the self-diagnostic function.

2.	Tune to the FM radio station you wrote down in preparation using the SEEK/SKIP () or SEEK/SKIP () button, and note the decibel level of that station.

3.	Press and hold the FM/AM button to enter the AM reception mode.

4.	Tune to the AM radio station you wrote down in preparation using the SEEK/SKIP () or SEEK/SKIP () button, and note the decibel level of that station.

5.	To end the self-diagnostic function, press the VOLUME/POWER () knob, or turn the vehicle to the OFF mode.

Compare your results to a known-good, (make sure it is the same year and trim level) in the same location and direction, and under the same environmental conditions.

	If the reception level is within 10 % of the known-good vehicle, no repair is needed at this time.
	If the reception level is at least 10 % less than the known good vehicle, go to Poor AM or FM radio reception or interference troubleshooting.
