PROCEDURE

1.CHECK CONDITIONS AROUND THE TIME THE PROBLEM OCCURRED
a.

Check for situations/locations when noise occurs.


Result:
Result Proceed to
Noise occurs in all areas A
Noise occurs in specific areas B



A

2.CHECK FOR ADDITIONAL DEVICES (SUNSHADE FILM, TELECOMMICATIONS ANTENNAS, ETC)

B

RADIO WAVES ARE DISTURBED (RADIO WAVE ENVIRONMENT, ETC. EXTERNAL FACTOR)

2.CHECK FOR ADDITIONAL DEVICES (SUNSHADE FILM, TELECOMMICATIONS ANTENNAS, ETC)
a.

Check that there is no sunshade film or additional devices such as a telecommunications antenna installed.

OK:

AFTERMARKET DEVICES (INCLUDING NON-GENUINE WIRING) ARE NOT INSTALLED


HINT:

The vehicle is equipped with noise filters that prevent other systems in the vehicle from affecting the radio. Therefore, the system will not be affected by large interference. If the system is affected by large interference, confirm that no non-standard wire harnesses are installed, all of the noise filters are installed correctly, and the mount of the antenna is correctly earthed.
