Toyota Corolla (E120): Noise occurs
Inspection procedure
1 Check of speaker installation
- Check speaker installation condition.
- Check that each speaker is securely installed.
Standard: malfunction disappear.
Hint
: the radio is equipped with noise prevention system that does not work against the regular use of the radio, thereby excessively large noise cannot occur in the radio. If large noise occurs, check whether or not the earth on the antenna installation part and the proper noise–prevention equipment are all installed, and whether or not the improper wiring is held.
Hint
:
- identify the condition under which the noise occurs, and check the noise filter on the related part.
- Make sure first that there is no noise from outside. Failing to do so makes the noise occurrence source detection impossible and leads to misunderstanding.
- The noise should be removed in descending order of loudness.
