✅ Reverse sensor VAZ 2107 5 mortar

If the white lights on the rear of the “Seven” stop glowing when moving in reverse, then the malfunction requires immediate correction. Not only do non-working reverse lights do not meet the technical requirements for the car and traffic rules, but this breakdown misleads other road users and can provoke an accident; as a rule, the reverse sensor on the VAZ 2107 can be to blame.

Usually, in order to eliminate such a malfunction, it is necessary to replace the VAZ 2107 reverse sensor. It is not necessary to spend time and money on a visit to service station specialists - you can diagnose and replace the sensor yourself. But first you need to make sure that it was he who caused the malfunction.

Self-replacement of the VAZ reverse sensor

Today we will change such a thing - the VAZ reverse sensor.
Have your neighbors started complaining that when you reverse in your favorite VAZ, it is not noticeable to others? Well, it's time to change the reverse sensor and forget about all the problems, including the neighbors. What could be the reasons for the rear lights not shining? How to do it yourself? Is it difficult and what is needed for this? What should I do in what order? This article provides answers to all these questions; it also contains supporting photos showing how to correctly replace this sensor on a VAZ 2106, 2108 and other models:

Stop signal

The brake light switch is located on the brake pedal hanger holder . The brake light is turned on as follows: when you press the brake pedal, the spring in the switch presses the control pin. At the same time, the contacts in the switch close the brake light circuit. When the brake pedal is released, the pin returns to its original position and the brake light goes off.

If the brake lights do not work on a VAZ-2107, you should make sure that the cause of the malfunction is not in the switch. To do this, you need to unscrew the ends of the power wires and place a jumper between them: if the brake lights turn on, the switch should be repaired or replaced. To replace the brake light switch, you must turn it clockwise 90 degrees and remove it from the mount. After installing the new switch, make sure that the neck of the switch fits snugly against the brake pedal and turn it 90 degrees counterclockwise. The new switch is adjusted automatically when the brake pedal is pressed. The switch operates normally if the brake light is turned on no earlier than the brake pedal has been moved 5 mm, but no later than it has been pressed 20 mm.

Fuse F11 is installed in the brake light circuit, which, in addition, is responsible for the operation of the interior body lighting.

Some VAZ-2107 owners install an additional brake light so that the signals given by the driver are more visible on the road. This type of brake light is usually placed on the rear window inside the cabin and operates on LEDs.

Reasons why the reverse lights of a VAZ car do not light up

Why might the reverse lights not light up?

First, you need to find out why the reverse lights do not light up - maybe the bulbs are simply burned out (see Replacing bulbs in the rear light of a VAZ 2110: do it yourself) and you don’t even need to change the sensor? Here are some reasons:

The reverse lights are burnt out. You can check their performance by removing them from the flashlights and checking them with a multimeter.

Damaged wiring is another reason. Everything is more complicated here - you will have to search longer. And it is checked in the same way - using a multimeter for continuity or resistance.
Poor contacts on the reverse sensor. As you know, nothing with poor contact usually works.
Violation of the insulation on the wires near the sensor leads to their short circuit.
The fuse has blown (see VAZ 2110: how to replace fuses). Which one needs to be clarified for each car in the repair manual.
Well, the breakdown of the sensor itself - this is evidenced by both the lights not turning on when reverse gear is engaged, and the constant glow of the lights.

To fix a malfunction of the lights, you may have to perform all the repair points, but you can start with the sensor. The price for it is small - usually about 100 rubles, so you can buy it and change it, and then solve problems as they arise.

Tools

So, what do you need to replace the reverse sensor yourself:

A set of keys. Although this is even said loudly. You will need a 22 key and in some cases a 24 key

An extended 22mm socket will be needed to remove the reverse sensor

Multimeter

Be sure to get a multimeter

Small container for oil
Screwdriver
Pliers
Knife
Insulation tape
Hammer
Chisel

ABOUT THE SIGNS OF DZH MALFUNCTION AND ITS SEARCH

It is safe to say that there can be only one sign when the VAZ 2114 reverse sensor does not work, this is the absence of lighting when driving the car in reverse. But there are quite a few culprits for this. It could be:

Fuse F16 (15A) has blown;
Oxidation of contacts in flashlights;
Poor contact of the connector with the fuse block;
Broken wires;
The sensor output terminals have oxidized;
The light bulb has burned out.

Often the culprit of such problems is the light bulb socket, where oxidation of the contacts occurs due to poor sealing of the lamp.

TROUBLESHOOTING

The location of the reverse sensor on the VAZ 2114 (2115, 21113) has already been clarified, let's talk about how to determine the true cause of the malfunction. To do this, it is advisable to have a measuring device such as a tester or multimeter, a light bulb with two wires, but in some cases you can do without them.

The check procedure could be as follows:

Open the hood of the car, and then the fuse box cover;
Check fuse F16 and replace it with a new one if necessary. If after this the lighting does not light up, continue the search;
Find and check fuse F 16
The device checks the presence of electrical voltage at the fuse legs when the ignition is turned on. It should be equal to 12 volts. If it is absent, poor contact between the connector and the fuse box may be to blame. If there is tension, then move on;
The search moves down under the car. You need to turn on the ignition and reverse gear. But before that you need to remove the engine protection. After this, check the supply voltage to the DZH connector;
Connect the device or control light with one wire with ground, and the other end with an orange wire. The “movement” of the instrument needle or the glow of a light bulb indicates the presence of supply voltage;
The next step is to short-circuit the conductors of the DZH connector to each other. If lighting appears, then we can safely say that the VAZ 2114 reverse sensor has failed. If it is absent, the search continues. The troubleshooting algorithm for VAZ 2109, VAZ 2113, VAZ 2115 is the same.

The diagnosis has been made, and now they are starting to treat it.

Replacing the sensor

And now it’s time to consider the process of replacing the reverse sensor on various VAZ cars - from 2106 to 2115. Here are the instructions.

VAZ 2107

Let's start with the Classics

Let's start with the VAZ 2107 car. On VAZ Classic models everything is done exactly the same.

Advice! Before replacing the sensor on any car, clean the gearbox housing from dirt to make it easier to find the sensor and to prevent dirt from getting into the oil.

First, we look for the sensor - it is located on the right side of the gearbox, if you look at the car as it moves. It is very difficult to make a mistake - this is the only part in the gearbox where two wires fit.

Sensor location on Classic

If the wires are broken, then look for protruding contacts.
If the wires are still on the sensor, then disconnect them.
Next, you will need a 22 key. They need to unscrew the sensor. For convenience, it is better to take a longer wrench, since over time the sensor will stick to the crankcase.
If you cannot unscrew the reverse sensor using a wrench (head), then you need to do this using a hammer and chisel.

Note! The gearbox housing is very fragile. Therefore, be extremely careful not to damage it with hammer blows.

Then clean the seat from dirt using a knife.
Remove the metal washer along with the dirt and replace it with a new one.
Insert the sensor and tighten it using the same wrench until it stops.
Next you need to put the wires back on. If necessary, crimp the contacts with pliers.
And now, the replacement of the reverse sensor on the VAZ 2107 is completed!

Some people have a question about oil - whether it will leak or not. In this case it will not leak.

VAZ 2109

VAZ 21099 replacement reverse sensor

Let us remind you that this point applies to the Samara family as a whole, and not just to the VAZ 2109 car:

Remove the protection from the car engine, if any.
The location of the sensor on a VAZ 2108 and similar cars is slightly different than on a Classic, since the car has front-wheel drive.
As the vehicle moves, the sensor is located on the left side.
If the Classic had to be driven into a viewing hole, then cars with front-wheel drive can simply be lifted under the left front wheel using a jack.
Again, the electrical wiring leads to the sensor.
Remove the wires.
To remove the sensor you will need an extended 22mm socket and a wrench.
Using the head, remove the sensor.

VAZ 2109 replacement of reverse sensor

Remember! Replacing a reverse sensor on a front-wheel drive vehicle is characterized by small oil leaks from the gearbox housing.

Prepare a container and, as soon as you unscrew the sensor, place it so that the oil does not spill on the floor.
Insert the new sensor as quickly as possible.
Screw it in by hand first and then tighten it using the same socket and ratchet.
Connect the electrical wiring wires.
Add the required amount of oil.

VAZ 2110

Cars of the VAZ 2110 family are equipped with engines from the VAZ 2108. Therefore, there is no point in writing the same information a second time. The answer is: VAZ 2110 replacement of the reverse sensor - see the information above.

VAZ 2114

Replacing the reverse sensor on a VAZ 2114 or cars of the Samara-2 family. Instructions:

The essence of the process is the same.
Raise the car using a jack.
If necessary, remove the engine protection, but this may not even be necessary.
Find the sensor; on new gearbox models of Samara-2 models it has a slightly different location, but finding it will also not be difficult.
Disconnect the electrical wiring connector from the sensor.
Using a 22mm wrench (it’s more convenient to use a head, but you can also use a wrench) unscrew the sensor.
Before removing the sensor from the connector, place an oil container.

Note. It is best to replace the sensor on a cold car, as less oil will leak out. Although this is not important.

Take out the old sensor and insert the new one along with a new ring.
Screw the sensor using a wrench or socket.
Wipe the gearbox housing from oil traces.
Connect the wires.
Top up the oil level in the gearbox to the required level.
Reinstall the engine protection (if necessary).

So, the sensors have been changed. Now you can start checking their functionality.

Diagnosis of problems

The reverse sensor on the VAZ 2114 may fail over time as a result of non-compliance with the operating rules of the vehicle.

To diagnose its condition, perform the following actions:

turn the wheels to the left;
looking for contact protection;
remove protection;
consider the device itself and a pair of contacts going to it;
perform a “frog” closure;
engage gear (fourteenth).

If there are no problems with the wiring, contacts and light bulbs (the performance of all these elements is important), the white lights will light up. When there is no switching on, the tester measures the voltage of the red wiring and ground. If there is voltage, check the board. When there is no light, the contact of the sensor or safety valves has probably broken, it is necessary to test the entire unit. The DZH should be located and checked using appropriate equipment.

The main reasons for sensor failure:

the contact points of the lights at the rear have oxidized;
the sensor itself is loose, it should be screwed in as deeply and tightly as possible;
there is no normal contact with the wiring on the car box;
there is no proper contact between the safety block and the plug device;
The fuse burned out and damaged the contacts.

In theory, any fuse in the chain can blow out, which will negatively affect all contacts.

Functionality check

And now the moment has come when everything should work:

Put the car in reverse gear.
Turn the ignition key.
In this case, there is no need to start the car, as some “experts” write about it.
Positive result - both reversing lights are illuminated.

If a positive result is achieved, please accept my congratulations. If not, then let's dig further.

What to do if replacing the sensor did not help?

Earlier in this article, a list of possible reasons was given for why the reversing lights do not light up. The reason could be any of the above, or it could be all of them. Therefore, step by step you will need to take steps to eliminate each of them, and then you will succeed. A video is also provided to help you, which clearly shows how to replace the reverse sensor.

How to change the reverse sensor on a VAZ 2107

The design of VAZ 2107 cars has a light alarm that indicates that the car is moving in reverse. This is one of the main indicators by which accidents can be prevented. The operation of this light alarm depends on the functionality of the sensor. However, situations often arise when the VAZ 2107 reverse sensor fails, which leads to the need for immediate repairs.

Causes of reverse lights not working

If you find that the light on the seven does not light up when reversing, then you need to immediately identify the problem and fix it. Most likely the reason will be:

Fuse blown. If any electrical appliance or circuit malfunctions, the first step is to check the serviceability of the fuses. From the name you can guess that the essence of a fuse is to protect an electrical circuit from high current and short circuit. If the fuse is blown, it needs to be replaced and the lights will work properly.
Bulbs burn out. One of the reasons is the burnout of the lamps, but this factor is easy to exclude, since if the lamps burn out, not both of them burn out at once.
The integrity of the wiring is compromised - mechanical stress often contributes to damage to the wires. Rarely is the cause of their damage due to a short circuit. To determine if the wiring is working properly, you will need to use a multimeter by ringing each wire or measuring the voltage on the lights.
Sensor malfunction - it is also called the reverse switch, since it is responsible for turning on and off the light alarm. Moreover, it may either break, in which case it will need to be replaced, or the terminals may oxidize, compromising the quality of the contact connection.

The sensors on 4- and 5-speed gearboxes of 7s are different. You need to pay attention when purchasing.

Malfunction of the reverse sensor is quite common, so you first need to check the integrity of the fuse, then make sure there is voltage on the lights, and only then proceed to replace the switch in question. Moreover, its malfunction can be manifested not only by the lack of lighting of the lights, but also by constant burning. If the 3X lights are constantly on, then it is necessary to replace the sensor.

How to find the reverse sensor VAZ 2107

The element in question, which is responsible for turning the rear lights on and off on the VAZ 2107, is located in the main mechanism - this is the gearbox. To find the location of the switch, you need to crawl under the car and look at the box. The element is attached to the bottom of the gearbox on the right side.

It is impossible to confuse it with another sensor if you know where the box is and what it looks like. There is only one sensor installed on the box, not only on carburetor, but also on injection modifications.

This small part cannot be repaired, so if it is found to be faulty, it will need to be replaced. To make sure that the cause is in the device in question, you should remove the lead wires from the sensor terminal, and then move the gear shift lever to the reverse position. Set the multimeter regulator to the continuity position and touch the two contacts with the probes. If the device emits a sound signal when the reverse gear is engaged and, on the contrary, is silent when the lever is moved to the neutral position, it means that the element is working and you need to look for the cause in other components. Knowing where the frog is located on the VAZ 2107, it will not be difficult to check it further.

Required parts and tools for replacement

The device in question is not the most important part on the car, however, if it malfunctions, an accident may occur. It's not worth the risk, especially if you know that your reverse lights won't turn on. To change the reverse sensor on the seven, you will need to put in very little effort.

Replacing this element lasts no more than 30 minutes, but after the work done, you will put your vehicle in order. To make a replacement, you will need a new sensor, as well as some tools, or rather a “22” wrench, which will be used to unscrew the part, as well as silicone liquid lubricant for processing the contacts. A long socket head on “22”, if available, will help to simplify the replacement of the part.

Changing the sensor

When replacing the 3X sensor, you must first clean the location of this part on the box. This is necessary in order to prevent dirt and dust from entering the mechanism. You need to carry out work to replace the reverse sensor on the seven from the inspection hole, following the following sequence:

Disconnect the contacts from the part (there are two of them). In this case, it is not at all necessary to disconnect the terminals from the battery, since the possibility of shorting the wires is excluded (after all, they are protected by plastic clips).
In the next step, you need to take the key to “22” in your hands, and then unscrew the old and faulty element. The old element must be dismantled together with the metal sealing washer.
If the element cannot be unscrewed, which happens quite often, then you can use WD-40 solvent, and if the lubricant does not give results, then you need to take a hammer and chisel. If the sensor is unscrewed with a hammer and chisel, then the actions must be performed with extreme caution.
After unscrewing, you need to clean the element seat.
Replacing the VAZ 2107 reverse sensor requires the preliminary installation of a metal sealing ring on the threaded connection.
After this, you can screw the device into the hole, tightening it with a wrench, applying manual force.
Finally, you need to connect the terminals to the terminals of the device, and then check the serviceability of the light alarm.

After the new element is installed, it is recommended to treat the contacts with silicone grease and also make sure that the contact connection is reliable. If the contacts are not connected reliably, the reverse light alarm will not work properly. After completing the work, you should check the serviceability of the light alarm.

Description of DZH

Purpose

Let's start with the purpose. DZH is a device designed to activate white lamps, indicating that the car is in reverse gear. The device is used to turn on the reversing lights, which allows other road users to know the driver's intentions and the maneuvers he is about to perform.

When it's dark outside, white headlights will also help warn drivers behind you that your car is in their path. This, in turn, helps prevent possible incidents and emergency situations on the road. Where this device is located - the location may vary slightly, but as a rule, the controller is located on the gearbox.

Design and principle of operation

The DZH itself consists of a housing, contacts for connection, a rod, a moving ball, and a return spring.

As for the operating principle, it is as follows:

The driver shifts the transmission lever to the reverse gear position.
In this case, the gear shift fork is pressed against the controller.
Next, the device shorts the cable to ground.
After this, the light source installed in the rear lights is activated, which warns other drivers that the car has started to reverse.

Symptoms of a problem

What signs of malfunction may indicate a breakdown of the DZH:

One of the problems that happens most often is oxidation of contacts on the terminals or wiring. This problem is relevant for many car owners. To solve this problem, it is necessary to thoroughly clean the contacts and then install them in place. When performing this work, the battery should be disconnected. If the contacts are inoperative due to the fact that they are burned out, then they will have to be changed in any case. But before making a replacement, it is necessary to find out why the burnout occurred; most likely, the essence of the problem lies in voltage surges in the on-board network.
The device became loose in its seat. During vehicle operation, the controller may slightly move out of its installation location; this problem is usually caused by high vibrations. In this case, you will simply need to more securely fix the device at the installation site.
Another reason for inoperability is the lack of contact with the on-board network in the gearbox. In this case, it is necessary to diagnose the condition of the contacts, as well as electrical circuits. If necessary, failed components must either be cleaned or replaced.
The next problem is that there is no contact between the connection connector and the safety mounting block. In this case, you also need to diagnose the condition of the contacts, as well as clean and change the wires, if necessary.
Failure of the safety device. In this case, the problem can only be solved by replacing the fuse. If this part often fails, then the reason may lie in the same voltage surges. It is necessary to check the electrical circuit more carefully.
The reverse light may not turn on because the light source itself, that is, the lamp, has burned out. In this case, you will have to dismantle the optics cover in the trunk and replace the failed device.
And finally, the last reason for inoperability is the breakdown of the DZH. In this case, you will not be able to repair it, since such devices, as a rule, cannot be repaired. The controller will need to be changed (the author of the video is the Do-It-Yourself Auto Repair channel).

Replacement of reverse sensor VAZ 2107

Symptoms of malfunctions

Of course, it is very easy to suspect that the reverse sensor is not working - when you engage reverse gear, the lights do not light up.

In such a situation, there are only three options for the development of events:

The light bulb itself has burned out, so the element itself may be intact.
The power fuse has stopped working. It’s not uncommon for him to simply burn out.
The sensor itself does not work. This does not happen so often, but you will have to check its condition.

Is it because of the sensor?

Indeed, how can one determine that it is the one that has failed and not a fuse or light bulb that has blown? Everything is quite simple.

You will have to remove the fuse and check it for integrity. For a VAZ 2110 car, it is planned to install a fuse number 19, the rated current of which is 7.5A. It is located in the mounting block, and the mounting block is under the dashboard.
Check the condition of the lamp. If everything is fine with it too, then there is only one option left - the reverse sensor has broken.

Why don't the reverse lights come on?

There are several reasons why the lamps in the reversing lights may not light:

The fuse protecting the power supply circuit for the reverse lamps has blown. The breakdown is visible visually; you just need to pull the fuse out of the block.
The lamps have burned out. To check the functionality of the lamps, they should be removed one by one from the lantern and make sure that there is no break in the spiral using an ohmmeter (multimeter) or a continuity tester.
Wiring is damaged. You can also check it using a multimeter and a continuity test, but finding a break will be much more difficult.
Poor contact of wires with the terminals of the reverse sensor. The check should begin with a visual inspection and cleaning of dirt and oxides. Then you can use a multimeter to measure the resistance of the circuit.
There is a short circuit in the power wires. You can check the absence or presence of a short to ground wire with a continuity tester or a multimeter.
The reverse sensor of the VAZ 2107 is broken. You can check it with a continuity tester or a multimeter. Visually, the malfunction is expressed in the fact that the reversing lights either do not turn on at all or are constantly on.

parking lights

The dimensions on the VAZ-2107 are activated by the leftmost of the four key switches located under the gearbox control lever. This switch is a three-position switch: the side light, along with the license plate light and instrument lighting, is turned on in the second position.

The side lights are activated by a three-position switch located under the gearshift lever.

On the fuse block, which is located under the hood of the car near the windshield closer to the passenger seat, the rear side lights fuses are numbered F14 (8A/10A) and F15 (8A/10A). In this case, fuse F14 is responsible for the operation of the side lights of the left front headlight and the right rear light, as well as:

a lamp indicating the operation of the dimensions;
license plate lights;
engine compartment light bulbs.

Fuse F15 is installed in the side light circuit of the right headlight and left rear light, as well as:

instrument lighting;
cigarette lighter lamps;
glove compartment lighting.

If one of these lamps does not work, you should check the integrity of fuses F14 and F15.

Fuses F14 and F15 are responsible for the operation of the side lights.

Where is the reverse sensor located on the VAZ 2107?

On the “seven”, as on all “classic” VAZ models, the reverse sensor is located on the gearbox. It is attached to the bottom and right of the gearbox, when viewed in the direction of travel of the car.

It is impossible to confuse it with something else - this is the only part on the gearbox to which it happens that the wires going to the sensor are broken. In this case, it is easy to distinguish by a pair of protruding contacts.

What is needed for replacement

To change the part, you only need two things: a 22mm wrench and a new reverse sensor with a metal washer-spacer. It is advisable to use a socket wrench with a long wrench. But, if you don’t find one, you can get by with a cap or even a carob.

Principle of operation

Connection

This regulator works more than simply:

You shift the gear stick to reverse;
Simultaneously with turning on the reverse speed, the shift fork is pressed against the sensor;
A wire short to ground is created;
The light turns on, indicating that the car is starting to move in reverse.

How to change the reverse sensor on a VAZ 2107

Before replacing the sensor, it is advisable to clean the gearbox of dirt. If this is not done, it may get into the oil, which is located in the crankcase. Replacement of the VAZ 2107 reverse sensor is carried out in the following sequence:

disconnect the wire tips from the sensor contacts;
Using a 22mm wrench, unscrew the old sensor from the gearbox, removing it along with the metal washer;

Note: if the sensor is “stuck” and cannot be unscrewed with a wrench, you can try to unscrew it using a chisel and hammer. However, this must be done extremely carefully so as not to damage the gearbox housing, which is made of a fragile aluminum alloy.

clean the sensor seat;
put a new washer on the new sensor and screw it into the gearbox using a 22mm wrench;
Place the wire ends on the sensor contacts.

Now you know how to change the reverse sensor on a VAZ 2107. After installing the new sensor, pay attention to how tightly the wire tips fit on the sensor contacts. They should not dangle or fall off. If necessary, tighten the tips using pliers. It is a good idea to clean the tips before placing them on the sensor contacts. This way you can be sure of reliable contact on this connection.

Dear! Why do you need a so-called electrical circuit diagram if you call a switch a sensor? Here is a guide to replacing the switch. There are no sensors at all on the gearbox. The term sensor comes from the same root Russian word to give, to issue. What “toad”?! checking and replacing the reverse light switch on a VAZ 2107. Checking the reverse light switch on a VAZ 2107. 1. Place the VAZ 2107 on an inspection hole or overpass (see “Preparing the VAZ 2107 for maintenance and repair”). 2. We clean the place where the reverse switch is attached and the switch itself from dirt. 3. Disconnect the wire blocks from the reverse switch terminals.

After connecting the wires to the terminals of the reverse switch, apply grease to them to protect them from water and dirt. Thank you very much for the detailed information. The car was bought in poor condition. The circuit for switching on the reverse lights is, to put it mildly, broken. I looked at the circuit from the light bulb to the switch (toad), but then I don’t know. There is a diagram, but I can’t find its description. Maybe someone can tell me? Thanks in advance!

Thank you
I do not like

Thank you very much for the detailed information. The car was bought in poor condition. The circuit for switching on the reverse lights is, to put it mildly, broken.

Descriptions of the operation of the elements in accordance with the diagram, at least I don’t remember seeing them. The diagram is read in the direction from the “plus” terminal on the battery through the wires, through the elements and “ground”, that is, the body to the “minus” terminal. In front of you is the so-called interactive diagram. So lay a path from “+” through the “ignition switch”, “relay and fuse mounting block”, “reverse light switch” and “flashlight lamp” to “-” or vice versa.
