INSPECTION PROCEDURE
PROCEDURE
1. CHECK SPEAKER INSTALLATION
(a) Check the speaker installation condition.
(1) Check that each speaker is securely installed.
OK:
The malfunction disappears.
HINT: The radio is equipped with a noise prevention system that blocks excessively loud noise. If such noise occurs, check that all wiring is proper and that the antenna installation part ground and noise-prevention equipment are installed.
HINT:
- Identify the conditions under which the noise occurs, and check the noise filter on the relevant part.
- First ensure that the noise is not coming from outside. Failure to do so makes noise source detection difficult and may lead to a misdiagnosis.
- Noise should be removed in descending order of loudness.
NG -- INSTALL SPEAKER PROPERLY
