Note: Catalog numbers of sound signals see here.
Depending on the configuration, the Lada Largus can be equipped with one or two sound signals of different tones. The sound signals are located behind the front bumper on the left and right. If the car has only one signal, it is located on the right side (high tone). If there are two signals, then the low-tone one is installed on the right and the high-tone one on the left.
High and low tone signals are marked differently. The high tone signal is designated by the letter "H" (hight), and the low tone signal is designated by the letter "L" (low).
Removal
Place the vehicle in the work area, apply the parking brake, and turn off the ignition. Raise the hood, disconnect the ground wire terminal from the battery (10 mm spanner).
Note: To remove the horns you can either remove the front bumper (it takes a little longer, but it's more convenient to work with), or remove only the front fenders. To remove the bumper, you will need to remove the mudguards in any case, so you should start with them and then decide in a specific case whether you will need to remove the bumper. Mountings may vary slightly between vehicles. Experience shows that to remove the left signal together with the bracket you need to remove the bumper, but for the right one - this is not necessary.
Remove the mudguards and front bumper (see here).
Disconnect connector 2, Figure 9-1, of the front wiring harness from the horn.
