Hello everyone, today I would like to talk about why the signal on a Lada Largus car does not work. Largus has a two-tone sound signal. There is also no signal relay, and both signals are connected when turned on through a fuse. If it suddenly happens that you press the signal, by the way, the button for turning on the sound signal on Largus is located on the steering column switch on the left, and you do not hear a sound, it means that something went wrong and the first thing you need to do is check fuse F17 (15A).
If necessary, you need to replace the signal fuse, and if after replacing it burns out again, then you need to look for the location of the short circuit. After checking the fuse, if it turns out to be serviceable, then the cause should be looked for in the steering column switch.
In the steering column switch, the black wire at the base of the soldering tends to break off, and in this case you have two options: buy a new switch, which is not that cheap, or do soldering, provided that you know how to do it. Possible malfunctions of the Lada Largus sound signal also include the sound signals themselves. But the likelihood that both will refuse at once is very small.
Well, that’s all we have looked at the main reasons why the sound signal on a Lada Largus car does not work. Bye everyone.
Removing sound signals Lada Largus
We carry out work when replacing sound signals.
Depending on the configuration, the vehicle may be equipped with one or two sound signals. The signals are located behind the front bumper. If there is one signal (high tone), it is located on the right side, if there are two signals, on the right - high tone, on the left - low tone.
. Using a 13mm wrench, unscrew the bracket fastening bolt.
. remove the signal with the bracket and disconnect the wire block from the signal connector (see above).
Set the low tone signal in the reverse order.
Replacing the sound signal on the Lada Largus
Note: see catalog numbers of sound signals here.
Depending on the configuration, Lada Largus can be equipped with either one or two sound signals of different tones. Sound signals are located behind the front bumper on the left and right. If the vehicle has only one signal, it is located on the right side (high tone). If there are two signals, then the one on the right is low-tone and the one on the left is high-tone.
High and low tone signals are marked differently.
The high tone signal is indicated by the letter “ H ” (hight), and the low tone signal is indicated by the letter “ L ” (low).
Place the car in the workplace, apply the parking brake, and turn off the ignition. Raise the hood, disconnect the earth wire terminal from the battery (10mm wrench).
Note: To remove the sound signals, you can either remove the front bumper (a little longer, but more convenient to work with), or remove only the front fender liners. To remove the bumper, in any case, you need to remove the fender liners, so you should start with them, and then decide in a particular case whether you will need to remove the bumper. Mounts on different vehicles may vary slightly. Practice shows that to remove the left signal, you need to remove the bumper together with the bracket, but for the right one, it is not necessary.
Remove the fender liners and front bumper (see here)
Disconnect connector 2, Figure 9-1, of the front wiring harness from the audio warning device.
1 — bolt for fastening the sound signal device; 2 — block of the front wiring harness to the audio signal device; 3 - sound signal device
Unscrew bolt 1 securing the sound signal device 3 to the car body (spanner “13”).
Remove the sound signal device assembled with the bar.
If necessary, unscrew the bracket nut and remove it from the signal.
Install the sound signal device in the reverse order of removal.
The tightening torque of the fastening bolt is 21 N.m (2.1 kgf.m) (replaceable head 13, extension, torque wrench).

Electrical problems
This is a typical disease of all Largus. The main reason is poor contacts installed at the factory.
- instrument readings constantly fluctuate;
- electrical appliances or one of them do not work;
- sensors fail;
- The ignition does not work due to high-voltage wires under the hood.
Troubleshooting
To repair the Lada Largus with your own hands in this case, you first need to determine the cause of the malfunction. Perhaps the contacts have oxidized, causing one or another electrical appliance to stop working. The wire may be broken. In this case, you need to test the circuit to understand which wire is faulty.
Replacing the standard sound signal in case of breakdown
First you need to prepare the car for work by putting the parking brake on and turning off the ignition. Then you need to lift the hood and, armed with a “10” key, disconnect the negative terminal from the battery. Then you should dismantle the front bumper, which is best done with an assistant, so as not to damage the paintwork on the bumper itself and on the wings of Vesta.
The figure shows the mounting location of the Vesta signal, its plug and the signal itself.
Once this is completed, all that remains is to disconnect the plug with the wires from the signal horn. Then you can dismantle the signal itself, the bracket of which is attached to the body with one nut. For dismantling you will need an extension, a wrench and a 13mm socket.
Removing and installing the front bumper requires an assistant.
Assembly is carried out in the reverse order - you need to secure the signal, inspect its operation, install the bumper with an assistant and tighten the terminal on the Vesta battery.
CV joint malfunction
A common malfunction of Largus is wear of the CV joint. This is evidenced by its characteristic crunch. This problem often occurs on new cars and is fixed under warranty.
A torn boot may be to blame for the wear of the CV joint. Dirt from the road gets into the mechanism, as a result the part stops working. To prevent this, periodically inspect the mechanisms and check the integrity of the anthers.
How to remove the Lada Largus standard radio and enter the code
- Files
- Engine
When removing the battery or for other reasons, the Lada Largus head unit requires entering a 4-digit code.
The code is usually written in the service book, but anything can happen - they lost the book, changed the radio, etc.
The radio code can be restored using our Renault and Lada Largus standard radio code generator
To do this, we need to find out the so-called PRE-CODE , which is contained in the information on the radio itself; to find it out, we remove the radio.
How to remove the standard radio of Lada Largus
The standard radio on the Lada Largus is removed in the same way as removing the standard radio on many Renault models, for example: Megane
For removal there is an original tool from Renault, code - 7711381821
But there is no need to buy it; 4 or even 2 regular ballpoint pen refills are suitable for removal.
Insert 4 rods into the holes around the perimeter to release the fixation (see photo below), you can pry it from below with a plastic card or a flat-head screwdriver. The rods can be inserted alternately, first 2 on the left, then 2 on the right.
To understand what you are clicking, here is a photo:
Reverse part of the Largus standard radio
How to find the PRE-CODE on the Lada Largus head unit
After removing the radio, we look for the barcode, we need the last 4 characters - 1 letter and 3 numbers
In this example it is: K068
We enter the resulting PRE-CODE into the code generator and get our code for the radio.
How to enter the code for the Lada Largus radio?
The code for the Lada Largus standard radio contains 4 digits.
To enter it, you need to dial it using the standard joystick of the radio or using the radio keys, after entering, press and hold the “6” button.
1. Press button 1 on the panel successively until the required value for the first digit of the code appears.
2. Press button 2, the second digit will start flashing.
3. Press button 2 on the panel successively until the required value for the second digit of the code appears.
4. Press button 3, the third digit will start flashing.
5. Press button 3 on the panel successively until the required value for the third digit of the code appears.
6. Press button 4, the fourth digit will start flashing.
7. Press button 4 on the panel successively until the required value for the fourth digit of the code appears. When the secret code is completely displayed on the screen, to save it in the radio's memory, press and hold button 6 on the panel until a confirmation sound sounds.

Wear of ball joints
This is a weak point on all seven-seater cars, as the load is much higher than on the five-seater versions. When buying a used car, ask in what conditions it was used and how often the Lada Largus was repaired. To assess the condition of the ball joints, contact a car service center or check them yourself on an overpass.
- knocking in the suspension when passing a speed bump;
- play when the wheels swing on an overpass;
- instability of the front wheels.
Repair
If you encounter such a problem, you need to immediately repair Largus in order to extend the life of the entire suspension. It is performed on a special machine for restoring ball joints, so you need to contact a car service center. Carrying out such repairs on your own is problematic.
Auto-assistance
The electrical circuit for connecting a two-tone sound signal on a Lada Largus passenger car is quite simple, since there is no relay for turning it on. It turns out that both signals, when turned on, are connected through the fuse and its power button directly to the battery power source or generator.
If, when you press the horn button located on the left lever under the steering switch (which is unusual for VAZ cars), not a single sound is heard indicating that the signal did not work, then the driver will have to look for a malfunction in his electrical circuit . First of all, you need to check the condition of fuse F17 (15A), which protects only this electrical circuit, located in the interior mounting block on the left side of the front panel. Its location can be determined by the pictogram printed on the back of the cover covering the mounting block.
Replace the blown fuse F17 with a new one. If, after turning on the sound signal, this fuse fails again, then you will have to look for a short circuit in its electrical circuit. And if fuse F17 turns out to be intact, then most likely you will have to look for a fault in the left under the steering switch, since it is there that the black wire most often breaks off at the base of the solder, as a result of which power to the sound signals stops being supplied.
There are two ways to fix this problem. The first way, which consists in replacing the steering switch, is the most expensive financially, since the prices for it are quite high. The second way is only for those drivers who can normally use a soldering iron and are not afraid to disassemble this one for the steering switch. To do this, you will need to remove the casing covering the steering column, unscrew a couple of screws and remove the switch housing. But, for soldering you will need a soldering iron with a thin tip, since the contact to which the wire needs to be soldered is located in a recess.
Possible malfunctions include the failure of the sound signals themselves, but the likelihood that both will not work at once is quite small. And if one of them refuses to work, then you can get to its location (behind the bumper) by removing the right or left wheel arch protection, depending on which of the sound signals has stopped working.

Remedy
Despite the fact that this malfunction is covered by the seller’s warranty, repairing the sound signal on Logan yourself is not so difficult, unless we are talking about replacing the entire assembly or a specific part. Logbook When the low beam is on, the horn (sound signal) does not work. The complex of work itself will not take much time and effort.
First, you need to disconnect the battery from the car's electrical network, and only after the current has disappeared should you begin disassembly. Renault Logan Car Enthusiasts Club View topic - Not working. After which it is necessary to dismantle the decorative plastic casing, which is attached using two self-tapping screws, while providing access to the switch mechanism. Instructions if the sound signal does not work on Renault Sandero. The lever with the platform must also be removed by unscrewing two screws. gelar wrote: where can I download Renault Duster the radio does not work, does it require a code? Intersections with TOP20 competitors on request:. The disconnected wire, more precisely, the place of soldering, will be visible, however, to guarantee a reliable result, you should check it with the car's wiring diagram.
The next stage of repair involves the use of a soldering iron. En: Renault Megan Scenic speedometer does not work. After degreasing the wire and contact, the end is soldered, and the wire is placed in such a way that it does not become crushed as a result of reassembly.
It is necessary to install the mechanism in the reverse order of repair, taking into account the connection diagram of the unit. After assembling the switch, connect the battery and check whether the horn works.
Of course, the described procedure is not a panacea in cases where the sound signal has disappeared, since the problem may be in the horn itself, and the causes of its occurrence can only be determined under appropriate conditions. Where is the fuel filter located on Renault Logan? Do valves bend when the timing belt breaks on a Renault Logan? However, as the practice of servicing this car model shows, problems with sound signals on Logans associated with wire damage occur in the vast majority of cases.
Floating idle speed
If your speed fluctuates while driving or idling, there may be several reasons:
- valves are deformed;
- cylinder head gasket burnt out;
- Malfunction of the idle speed sensor or throttle position sensor.
Using additional signs, you can find out the location of the malfunction - directly in the engine or in the sensors. The method of eliminating the problem also depends on this. You can see how to change sensors in the Lada Largus repair manual.
Besides. that the service life of domestic engines is short, car enthusiasts note their low torque and high fuel consumption. Another common problem is that when the timing belt breaks, the valves are immediately deformed. To prevent this from happening, you need to carry out timely maintenance and repair of the Lada Largus.
