How are sound signals on the cars repaired?

The sound signal is a fairly simple thing, but very serious. Despite the fact that we rarely use horns, it does not mean that it should not be in good order. When the audio signals do not work or emit a quiet squeak, respectively, the instruments need to be replaced. However, there are things that can be repaired. And even the Japanese signal of the sound "Toyota" is no exception. In this article, we will look at how to repair this part with your own hands.

Wire Condition

To begin with, if a fault is found, check the integrity of all the wires and evaluate their contacts. In order to do this, you need to remove the signal panel. The winding on the wires must be intact, without damage. Even if there is a small crack, this is the reason for replacing the damaged part. If you do not change the wire at this moment, after a couple of thousand it will still make itself felt. So do not skimp on the new details and change them in time in case of breakdowns. Sound signals after the replacement of the wire can again earn, but this does not always happen.

What if the horn does not work after changing the wires?

This indicates that you need to check the status of the relay and the switch. This is done with a special device - a multimeter. It can accurately determine the current state of the part. At visual inspection the whole picture is visible, therefore it is better to do check by the multimeter. If no clicks are heard on the relay, be aware that the car has a faulty electronic circuit. Also check the sound signals for voltage. To do this, again take the multimeter and connect it to the signal. We press on the horn and wait for the sound. If it did not appear, it indicates a complete malfunction of the device. In this case, you need to set new sound signals to the car.

Should I run to the car dealer immediately?

Of course, do not. Sometimes the horn can not make sounds because of the rust that has settled on its contacts. After negative readings of the multimeter you need to move a little, and it is best to disassemble all connections. In case of detection of rust it is necessary to remove it with the help of strong agents. If this did not work, the only way out would be to purchase a new part.

What if the sound signals are very quiet?

If the horn operates, but it produces a quiet sound, there can be several things immediately. First, you need to check the charge of the battery. If the green indicator is on the sensor, you should look for the breakdown in the horn itself. To do this, take a small screw and put it to the adjustment lever. Each time you scroll the screw a quarter, check the sound of the machine. Rotate it until the car starts to produce a "healthy" signal.

And finally a useful tip. When you assemble the disassembled part, pay close attention to the gasket, which is installed between the hull and the membrane. If it is not in the assembled parts, consider that all the work will be useless.
