The main reasons for the loudspeaker not ringing or hoarseness are the lack of battery storage, the damage of loudspeaker relays and buttons, the damage of the horn and so on. UseCarTesting equipment can find these questions one by one, and then give you a brief introduction.
1, the use ofCarTesting equipment to check the sound of the horn, if you feel the sound is not loud, low and weak, mostly contact contacts are poor.
2, repeatedly press the switch of the horn, if the horn sometimes ringing, sometimes not ringing, mostly according to the switch inside the contact is not good.
3, left and right rolling steering disk, if there is a larger "hissing" friction sound, can be to the relevant contact parts of the injection of some grease.
4, if the horn is not ringing at all, first useCarThe testing equipment checks the fuse to see if it fuses, then pulls out the horn Plug and uses a multimeter to measure whether there is electricity here when the horn switch is pressed. If there is no electricity, should check the horn harness and horn relay; If there is electricity, it is the horn itself problem, at the moment can also try to adjust the horn on the conditioning nut to see if you can sound, if it is still not ringing, you need to change the horn.
5, if the horn chirping dull, it is likely that the horn itself is faulty, then as long as a knock on the horn, most can be improved. The joints are poorly exposed, especially the lines around the steering wheel, because they are used frequently and simply lead to wear and tear.
6, the seal is not strict and easy to damp, although the inside of the horn is closed, but if the seal is not strict to wash the car, simple into the fog or internal space in the air water vapor, water vapor is very simple will cause the contact damp and can not work properly.
7, the operation of the Horn in theCarAt low speed, it is related to the operation of the battery, ifCarTesting equipment detected the battery energy drop, then the sound of the horn also decreased, to check whether the battery storage is normal.
In addition, when you press the Horn button, you can use theCarTesting equipment to check, see if the electricity has a circulation channel to the terminal of the horn, if there is an electric current to the terminal, but the horn is not ringing, to use in the inside of the horn adjustment nut to adjust.
