Renault Logan has a modern electronic speedometer. It, like any other device, is subject to breakdowns and malfunctions.
If the speedometer on Renault Logan failed, it is necessary to check the operability of the installed instrument panel. It is also worth paying attention to the serviceability of the speed sensor. It is installed on the manual transmission. The sensor can be found near the engine shield, at the top of the manual transmission.
The speedometer on Renault Logan does not work - some useful tips
It is necessary to diagnose the instrument panel - for this there is a special button, after pressing it, it is very important to hold the button itself in this position, while turning on the ignition. If there are no noticeable problems with the movement of the arrows of the shield, you need to get the speed sensor, after disconnecting it from the special plug. You need to do everything carefully and do not rotate the sensor itself.
Checking the performance of the sensor is simple - it is connected back to the plug, then the output shaft is clamped in the cartridge with a drill. Turn on a hand power tool - a partner will be able to see if the speedometer is working.
If in this situation the speedometer is working properly, the problem must be sought in the drive gears. These elements are made of plastic - when replacing them, you will have to partially disassemble the gearbox. If, after the procedure, the Renault Logan speedometer does not work correctly, the speed sensor will have to be replaced. You need to purchase an identical sensor - for this you need to use its catalog number, which is indicated on each part - this will allow you to buy the right part in any modern car shop.
Sometimes the speedometer needle just goes up - but it doesn't show the speed of the vehicle. You will have to dismantle the instrument panel, this will allow you to access the contacts that are responsible for the movement of this arrow. You need to carefully check them for any damage.
Often, the Renault Logan speedometer stops functioning correctly after visiting the salon and installing certain additional equipment. It's all about the mistake of the masters, who, when installing an alarm or other equipment, damaged the green wire. They used it to power equipment.
How to turn off the speedometer on Renault Logan
You just need to get the fuse for the ABS, it will no longer show the speed, the abs will also stop working. Mileage will not be counted. To resume the operation of all these systems - return the fuse to its original position.

Description of the beep
The location of the button for sounding the beep in Renault Logan is not usual. It is located at the end of the low beam and high beam switch. Such a location often confuses novice owners of such cars, but if you get used to it, then it is no worse than any other.
Feedback from car owners suggests that after a certain period of operation, this element often fails and the beep disappears. This is quite dangerous, because you may urgently need it on the road.
Signs and causes of malfunctions
The most common causes of malfunctions of this Renault Logan element include the following:
- breakage of the wire plus due to frequent twisting when the dipped beam is turned on;
- blown fuse responsible for this node.
Both of these problems can be solved with your own hands without any problems. You can understand that you have problems with this button by the operation of the beep itself.
It happens that it does not disappear at all, but sometimes it works, sometimes it doesn’t. This is usually due to the fact that in a certain position a broken wire begins to conduct a signal again. There are also malfunctions with the system of the horn itself, but they occur much less frequently.
In any case, if you notice a malfunction in the operation of this part, it is worth fixing them as soon as possible. The horn constantly helps the driver to prevent accidents and other dangerous situations.
The video below is devoted to the repair of the left stalk, on which the horn activation button is located (author - Aloshka Ya).
Do-it-yourself signal troubleshooting
Repairing a signal on Renault Logan in case of wire damage is quite simple, in a few steps:
- disconnect the battery from the electrical network of your car;
- dismantle the plastic casing by unscrewing the two screws to gain access to the switch;
- then remove the lever with the platform, they are also on two self-tapping screws;
- the place of soldering of the disconnected wire should be clearly visible, but to be sure, look at the electrical circuit of the car;
- after degreasing the wire and contact, solder the end of the wire;
- place the wire so that it does not break during assembly of the device;
- install everything in the reverse order, taking into account the connection diagram of this node.
After you complete the work, you can check the work with the klaxon. This diagram will help you solve the most common audio problem.
Video "The sound signal on Logan disappeared"
In this video, you will learn how to disassemble the regulator responsible for activating the horn and how to fix the main problems (the author of the video is the Renault Repair channel).
It is known that Renault Logan is a budget car, and therefore the manufacturer is trying to save on some of its elements in order to thereby reduce the cost of the car. Such systems also include the contact group of the sound signal, which is located in the steering column switches.
Audio repair video below.
The main reasons for the breakdown of the sound signal
Most car owners do not often use a sound signal in everyday life. But if such a malfunction is detected, then in the event that the car is under warranty and the signal stops working, you can contact an authorized dealer. You can also fix the problem yourself.
Understeering's shifter
The most common cause of signal failure is the included head lighting. The culprit in this switch, . It may lose contact. It is also noted that such a design cannot always withstand even the warranty period for a car. Since the entire bundle of wires passes along the axis of the switch, when the regulator is turned, the entire contact structure also rotates, as a result of which the contact itself disappears.
To correct the situation, you need to remove the lever. This will not take long if you have some experience.

Location of fuses in the main unit
Also, the sound signal may not work if the fuse blows. It is located in the mounting block in the passenger compartment.

It should be remembered that Renault Logan also has two more small blocks located in the engine compartment. It is recommended to check them all for blown fuses.
The beep itself
The sound signal itself can also refuse to work. It is located in the engine compartment on the left. It can only be accessed after removing the mudguard.

The battery must be disconnected.
conclusions
Knowing these points, you can independently identify the cause of the malfunction of the sound signal and eliminate it.
Before proceeding with the diagnosis and repair of the Renault Logan stove, we will briefly describe how ventilation and heating work for it.
It must be clearly understood that these systems work independently of each other.
So, heating and ventilation of the cabin, as well as the removal of frost and other types of moisture, is carried out separately from other systems. At the same time, the stove enters the heating system.
The main components of the heating system include a heater heat exchanger, also known as a radiator. The purpose of the radiator is to heat the air entering the cabin to a comfortable temperature set by the driver or passenger. The radiator heats up due to the circulation of coolant through it, which, in turn, heats up, removing heat from the running engine. The cooling system is closed and under pressure, so it can withstand temperatures over 100 degrees. With the help of an electric fan, you can control the intensity of the flow of warm air into the passenger compartment through the dampers of the air conditioner and heater.
This system also includes an electrically driven fan that provides and regulates the supply of outside air. Air is supplied to the dampers of the air conditioner and heater. The system also includes a damper for the air temperature regulator, which comes from the heater to the car interior. How you turn it will determine the amount of air that will pass through the heat exchanger of the heater, as well as the outside air that passes through the heat exchanger. It is also worth noting the air distribution flaps that come from the heater through the air ducts into the passenger compartment or in order to blow the windshield.
A little about the Renault Logan air conditioning system
The Logan air conditioning system is a compressor driven by a belt from the engine crankshaft pulley. The compressor pulley has a friction-type electromagnetic clutch that will disconnect the compressor shaft from the pulley or connect them when the air conditioner is running according to a certain signal from the electronic engine control unit.
During operation, the compressor compresses to a sufficiently high pressure the refrigerant vapor that will come from the evaporator heat exchanger. In this way, a significant reduction in temperature is achieved.
A pressure reducing valve is built into the compressor and can perform a protection function that is triggered when the pressure increase exceeds the value allowed at the outlet of the compressor itself. The reasons for the operation of the pressure reducing valve may include the failure of the valve, which is responsible for high pressure, as well as the failure of the electric fan. Other malfunctions are also possible.
The presence of a sound signal in a Renault Logan car allows its owner to avoid an emergency in some cases.
What to do if a malfunction of this important unit is detected and the sound does not come from the horn, that is, the sound signal does not work?
Some owners of Renault Logan express dissatisfaction with the sudden onset of this dangerous breakdown. Our material is addressed to this particular category of drivers, because it will consider the features of troubleshooting and measures to eliminate it. We will also tell you where the sound signal is located and how the sound signal is repaired.
The essence of the search
To quickly identify the reason that prompted the Renault Logan horn to remain stubbornly silent, you first need to check the fuse for its integrity. Sometimes a breakdown can hide directly in the signal, which also needs to be checked. Where the sound signal is located, almost every Logan owner has an idea.
- Let's get to the element.
- Armed with a multimeter, we control the presence of voltage at its terminals. The operation can be carried out with an assistant, since during this action (measurement) the sound signal must be activated by pressing the button on the steering wheel.
- If there is no voltage, we move to the mounting block to check the safety element.
- If the fuse is intact, but there is still no power, then we are looking for the cause of the malfunction in the steering wheel contact diagram.
- Next, you will need to disassemble the sound tone activation button with a detailed inspection of the state of its contact group. In most situations, it is the contacts that become the “culprits” of the loss of the signal, since at the moment the button is pressed, they may burn.
- The elastic elements of the button should be cleaned and lubricated. If the sound does not appear here, do not despair, we continue the search work.
- We check the relay for its ability to supply an electrical signal to the sound device.
- By pressing the button several times, we listen to the relay and, making sure that there are no signs of its viability, we replace it with a new element. Even with a working relay, power supply to its outputs may be lost. We check the integrity of the circuit.
- Sometimes there are malfunctions caused by the burnout of the high-voltage cable, through which power is supplied to the relay. Here we check the presence of voltage on the positive output of the relay. You can perform a test action using a multimeter, and in its absence - with a test lamp.
- When no voltage is detected, we disassemble the relay unit and look for an open contact. This work is within the power of the owner himself without the need to involve an auto electrician.
- We carefully check the integrity of the cable of the positive contact up to the head source, because no one is safe from loss of power in it.
- Among the common causes may be oxidation or a break in mass contact with the Renault Logan body. If there is a fact of a break, then this may be indicated by a failure in the operation of other current collectors of the on-board automobile network.
The indicated malfunctions are completely eliminated in a garage. The main condition is the adoption of security measures. If the sound signal does not work, after the manipulations, seek help from specialists.
Summing up
Repairing a sound signal in a Renault Logan car will require a simple set of tools and little experience in “communicating” with the electrical part of a Renault Logan car. Our material is suitable as an instruction that allows you to identify and fix a malfunction in accordance with the algorithm of actions indicated here.
