The reverse gear of the VAZ 2114 does not light up. The reverse light does not light up - what to do?

Many years ago, drivers never dreamed that their vehicle would be illuminated when reversing. Today this is an ordinary, one might even say, mandatory function for any car. lights not only helps drivers when reversing in the dark, but also warns road users about such a maneuver during the day. Therefore, drivers must know what to do when the lights are off. The reverse sensor, or DZH, as it is called in its abbreviated form, lights up the warning lights of the headlights.

How to search for this device

It is not difficult to find the place where the reverse sensor is located. Two devices are installed at the checkpoint, one of them will be the DZH. It is installed at the bottom of the gearbox. This can be clearly seen in the figure below.

Location of the household farm

You can get good access to it when the machine is on an overpass, a lift or above an inspection hole.

The purpose of this device is that when reverse gear is engaged, it should light up a white light in the lamps. The lack of lighting does not mean that it is him. There can be many reasons for this. For example, a light bulb or fuse has burned out, or a wire has come off.

About the signs of a DZH malfunction and its search

It is safe to say that there can only be one sign when the rear 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:

1. Fuse F16 (15A) has blown;
2. Oxidation of contacts in flashlights;
3. Poor contact of the connector with the fuse block;
4. Broken wires;
5. The sensor output terminals have oxidized;
6. 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

In order for the frog to be replaced, you need to prepare:

• New DZH;
• Adding oil to the gearbox;
• Key to "22";
• Rags for cleaning dirt from the installation site;
• Empty containers for transmission oil, since in the case when the reverse frog of a VAZ 2114 is changed, small quantity, may spill from the installation hole.

The machine must be installed on an inspection hole, on a lift or overpass. tighten. To make the work easier, you need to remove the engine crankcase protection. After this, you need to proceed as follows:

1. Determine where the VAZ 2114 reverse sensor is located and remove the connector with wires from it;
2. Clean the installation site of the DZH from dirt with a rag or other means;
3. Using the key “22” they begin to unscrew the device. In some cases this can be difficult to do. Over a long period of use, it can “stick” to the body of the box. A socket wrench for “22” helps out. If this does not help, there is still hope for the “old-fashioned method” - using a small chisel and hammer;
4. After the DZH has been moved from its place, an empty box is placed under its installation location, the spilled transmission oil is collected, and the device is removed.

Installation is carried out in the reverse order, having previously wiped the plane of the box where the DZH will be installed. Before installing a new product, it will be useful to perform a functional test. It's easy to do. Need to connect meter to its terminals, and with your fingers press several times on its protruding rod. The device should show it turning on and off.

If there were traces of leaks on the old DZH, the new product can be installed on a thin layer of automotive sealant. Tighten the device carefully, being careful not to damage the plastic part of the housing.

Check the oil level in the gearbox and add it if necessary. After checking the functionality of the system, the engine protection is put in place. The work is now complete.

A few words about choosing a DZH

We will not give any special advice on this matter. The devices may differ from each other only in the plastic housing of the wire connector. products can range from 100 to 250 rubles.

Failure of reverse lamps is a common occurrence on VAZ 2108, 2109, 21099 vehicles. Many car owners, after repeated lamp failures, leave them inoperative. Let's consider how to check their performance without instruments and accessories, repair them and bring them into proper condition. When carrying out work, remember that voltage is supplied to the rear light lamps on VAZ 2108, 2109, 21099 vehicles after the ignition is turned on.

Malfunction of reverse lamps occurs due to a number of reasons, here are the most common of them.

— Reverse light sensor faulty

The sensor is located at the bottom of the transmission on the left front wheel side. The orange (red) wire supplies current to it, and the green wire goes to the rear lights (the orange one is powered after turning the key in the ignition switch). With the ignition on, remove the plug with the green and orange wires from the sensor and connect them together with a piece of wire. The light comes on - we are changing the sensor. No, we are looking for a reason further.

— The fuse has blown

The reversing light is controlled by fuse F5 8 A (mounting block 17.3722), also known as F16 15 A (mounting block 2114). Through it, current flows from the mounting block through the orange (red) wire to the reverse light sensor. We replace it with a new one. In the future, it is necessary to find out the reason for the blown fuse, since it is possible that somewhere short circuit. It is worth noting that if this fuse blows, in addition to the reversing light, the instrument panel, “turns”, emergency lights, etc. stop working.

fuse F5 of the mounting block 17.3722 is responsible for the reversing light on VAZ 2108, 2109, 21099 cars

— There is no “ground” to the rear lights

The ground on the rear lights is the black wires from the blocks. Check that they are securely connected to the car body near the rear lights.

— The light bulb burned out

Either one or two light bulbs can burn out at once. Moreover, they may appear to be in good working order. You can check by inserting a known good light bulb into the socket, for example from the “stops” from the same flashlight.

— The contacts in the reversing lamp socket have oxidized

It is necessary to turn the light bulb in the socket several times to restore contact. To enhance the effect, you can clean the contacts with sandpaper.

— The contacts in the plug blocks of the rear lights wires have oxidized. We remove the pads and clean the contact of the green wire (pin 4) responsible for supplying power to the rear light lamps and the corresponding contact on the board track.

— Rear light boards are faulty

Their tracks may crumble or rust. We apply voltage with a piece of wire from terminal 4 of the green wire in the block to the lower contact of the light bulb inserted into the socket. If it lights up, we inspect the track on the board. You can solder wires onto it and restore the track.

— Not served electric current from the mounting block to the rear lights

Current is supplied to the rear light lamps through the green wire, from the transverse plug in the mounting block (W 9 or for 2114 - X9, pin 16), which passes through the entire interior of the car on the left driver's side. Perhaps the plug has become loose, or the tip of the wire has oxidized, or the green wire has broken somewhere. You can remove the plug from the mounting block and apply voltage with a piece of wire from the battery to terminal 16 of the green wire. The lamp lights up - the wire is working, no, we look for the place of damage or immediately replace it with a new one.

— The current supply wire from the mounting block to the sensor is faulty

Through it, current is supplied to the sensor and then through the green wire to the reversing light bulbs in the rear lights of the car. This is a red or orange wire from the leftmost plug in the mounting block (Ш6, X6/12) to the reverse light sensor. Engage reverse gear. Remove the Ш6 plug (X6) from the mounting block and apply voltage with a piece of wire from the battery to pin 12 of the plug. The light comes on - there is a problem with the mounting block, not with the sensor or the green wire.

— The electrical circuit supplying voltage to fuse F5 (F16) is faulty

In this case, the instrument panel will also not work. Items need to be checked electrical circuit for availability: terminal “30” of the generator – 2 pink wires – plug Ш8 (X8) pins 5.8 of the mounting block – plug Ш1 (X1) pins 6.5 of the mounting block – wires blue with black and brown to the ignition switch (brown current comes, blue and black goes to the fifth fuse) - ignition switch (terminals 30/1 and 15/1, they are switched when the key in the ignition switch is turned to the second position).

Notes and additions

- IN lately The quality of manufacturing of reverse light sensors for VAZ 2108, 2109, 21099 cars has deteriorated significantly. Their main problem is not tightness. After some time, the new sensor begins to leak oil from the gearbox through its housing. Therefore, you should periodically monitor its condition. A leaky sensor is the source of the occurrence, and this is unstable idling, loss of power and throttle response, subsequently failure of the elements of the ignition system and electrical equipment.

— Scheme for turning on the reversing light for VAZ 2108, 2109, 21099 cars — .

Lamps indicate that the car is moving backwards white, which are located at the “stern” of the car. If the car's reverse lights are not on, it will create an emergency situation - road users will not be able to predict its (that is, your) maneuvers. And parking in the dark will become a very difficult task - you will hardly be able to see anything without lighting.

Causes of the malfunction and ways to eliminate it

If the reverse lights of a VAZ 2114 do not light up, the reason may be as follows:
1. The light bulb has burned out. We simply replace it with an identical part.
2. Fuses are defective. Replace fuse F 16 and check the others. It is possible that the reason lies in one of them.
3. Contacts have oxidized. Remove the taillight block and clean all the contacts there, as well as at the 3/4 sensor.
4. A situation in which the reverse gear of a VAZ 2114 does not light up may occur due to the fact that there is no ground on the board (located under the lamp). We put it in place or just tighten it.
5. The power supply wire of the Z/X sensor is broken. We find an open circuit and fix it.
6. The travel sensor is faulty. This detail must be checked, since it is precisely this common cause the fact that the reverse lights of the VAZ 2109, as well as many other car models, do not light up. Place the car on the overpass, disconnect the wires from the “frog” and connect them “directly”. Turn on the ignition and reverse gear. If the light comes on, this means that the sensor is faulty and needs to be replaced.
7. The contact located on the headlight film has burned out. But this is one of the most common cases when the reverse gear of a VAZ 2115 does not light up, since this malfunction is a “disease” of all Lada SAMARA cars. You can cure it by replacing the standard board with an improved one, or by installing the contact group yourself.
We present to your attention some examples of such improvements.

That's all we wanted to tell you about this important and responsible topic. We hope you don’t need to explain how to change the reverse light on a VAZ 2114 or change any of the fuses. However, all other work to “eliminate” this problem is also not particularly difficult.

What are reverse lights? These are white road lights that turn on in reverse gear, guaranteeing safety while driving. If the reverse lights are not on, then the possibility of the driver getting into an emergency increases; it is very difficult to park in the dark when the road is not visible, and passengers will not be able to predict the actions of vehicles, which can lead to unpleasant consequences.

The frog signal device is a necessary device. As they say “in the language of a motorist”: everything that is in the car must function properly, the safety of vehicle traffic depends on it!

So, at the slightest breakdown or short circuit of the reverse light, you need to immediately begin repairing it. This can be done both at stations maintenance, and at home, quickly and very simply. And this theoretical basis will be a great help!

Causes of reverse gear malfunction

What could cause the lack of illumination to the rear headlights?

• The light bulb has burned out and you simply need to replace it by checking the contacts.

• The fuse has failed, which may impair operation. complete chain contacts.
• Lack of mass on the board, which is located under the lamp.

• Plaque and oxidation have formed on the contacts.
• If the wiring is broken, you can check it visually and also make a call.
• The contact on the headlight film burned out.
• Malfunction of the gearbox mechanism.

• The reverse frog of a VAZ 2114 has broken.

This is why the reverse lights on the VAZ 2114 do not light up!

There can be many reasons, which means that every driver should know how to properly eliminate such malfunctions.

Removing the backplane board

First you need to remove tail lights on a VAZ 2114, and for this you will need:

• Open rear trunk
• Remove unnecessary things
• Remove decorative trim
• Unscrew the plastic casing
• Take out the back panel

Now you have access to the socket and lamp of the rear license plate lamp, which also needs to be removed. The frog mounting pins are removed and the flashlight is already in your hands. The main thing is not to confuse it with the speed sensor, which is also located on the gearbox.

How to check the functionality of the frog?

The contacts from the sensor are removed and clamped together, after which the ignition is turned on. If there is light, then you need to replace the sensor. If not, then the problem is in the circuit, but the frog is fine.

When the reverse lamp does not light up, it is often necessary to replace the old sensor with a new one.

What to do:

• place the car on the overpass;
• install the handbrake;
• remove protection;
• remove the contacts of the old sensor;
• place the container and remove the frog;
• Unscrew the faulty device and replace it with a new one.

Attention, the price of a new sensor is within 250 rubles.

The next option is if the reverse light does not light up on a VAZ 2114, then the problem is in the light bulb. To replace it, you need to disconnect the wiring block, remove the plastic contact panel from the flashlight, while squeezing the side fixing elements.

We rotate the light bulb counterclockwise and, pressing slightly on the socket, remove it. Now we install a new one, check the contacts and put the entire unit back together.

We visually assess the condition of the wiring; if necessary, we strip the wires, check for breaks using the ringing method, and check the contacts on the headlight film.

Why aren't the reverse lights on yet?

A blown fuse is a common cause, which means you need to know exactly where they are located and how they change.

The products are located in the fuse box, which can be found under the steering wheel on the left side. It can be easily removed with just one touch of your hand. There is no need to unscrew anything.

When the reverse light does not light, you need to check the condition of the fuses. How to do this? You can visually look at the fuses and determine the breakdown - the integrity of the middle part.

But the burnt jumper is not always so clearly visible, so you need to turn on the dimensions and, without removing the fuses, check the voltage; if one end is on and the other is not, the device is faulty.

Attention: when such a breakdown often occurs, you need to check the entire electrical wiring system, which causes such malfunctions in the car.

To replace the product, you don’t need tools, just take tweezers, remove the old unit and install a working one.

You can find out where the VAZ 2114 reverse sensor is located very simply by looking up at the gearbox, and if the driver cannot get under the car, then the hood opens and thus the condition of the frog is checked.

To completely make sure that the brake gearbox is broken, you need to turn the wheels to the left and look at the gearbox from the driver’s side. There is a protection with contacts inside on the side, remove it, close the contacts on the DZH and turn on the ignition. When everything is in order, a white light appears.

If not, then use a tester to measure the voltage on ground and on the orange wire that comes from the frog. If voltage is present, then we check the flashlight board itself and clean the contacts.

There is also a chance that the contact between the frog and the fuse block has “frozen”; you need to find it and check its condition.

Attention: when everything is normal, but the lights do not light, the reason may be the contact of the lamp, so even when screwing in a new one, you must check its functionality. As the people say, it’s no joke, because a breakdown can be the easiest, but it can lead to a lot of troubles.

This is why the reverse light on the VAZ 2114 does not light up, as you can see, there can be many reasons, and for the motorist it is important to carefully check the integrity of all frog mechanisms, identify the malfunction and repair the functionality of the lighting.

Have a nice journey, good fellow travelers and a smooth road!

Reverse sensor(DZH) - is a device that activates the reversing lights (white) when you engage the appropriate gear and start moving in reverse. In this way, you notify motorists (pedestrians) standing behind you of your intentions, that is, that you are going to drive in the opposite direction.

Today we will talk not only about what this sensor is, but also how to check it if it malfunctions and replace it with your own hands, if necessary.

I would like to note right away that non-working reverse lights are not conclusive evidence that the reverse sensor is faulty; perhaps the reason is quite trivial, for example, a wiring has come loose or a light bulb has burned out. Therefore, in order not to make unnecessary movements, make sure that the reason is in this sensor, and not in the light bulb or wiring.

Additional reasons why the lights do not light up when reverse gear is engaged:

1. , which is connected by a DZH chain and lanterns;
2. Failure to fit the reverse sensor;
3. The contacts of the flashlights have oxidized;
4. There is no wiring contact between the fuse block and the plug.

Where is the reverse sensor located?

The DZH can be seen if you drive onto an overpass and climb under the car, there will be two sensors on the gearbox, one of them is - , the second - reverse sensor.

Symptoms of a faulty reverse sensor

You put the car in reverse, but the lights do not come on, although both the bulb and the wiring are in good condition.

How to check the reverse sensor on a VAZ 2114?

1. Disconnect the power wires from the reverse sensor.
2. Connect the wires directly to each other.
3. Turn on and .

Conclusions:

• If the lights are on in this position, the sensor is faulty and must be replaced.
• If even in this position the lights do not light up, the reason is in the circuit, the sensor most likely has nothing to do with it.
• Using a tester or multimeter, measure the voltage on ground and the orange wire that comes from the DZH; if there is voltage, you need to check the board of white lights, as well as the contacts. There may be no contact between the fuse block and the sensor contacts.

Replacing the reverse sensor on the "fourteenth"

To replace the sensor you will need: a new reverse sensor, an overpass, transmission oil, as well as empty containers and rags. The fact is that when you unscrew the old ESD, oil will flow out of the hole.

1. Drive the car into the pit and place it on.
2. Remove the engine crankcase protection.
3. Remove contacts from DZH.
4. Carefully clean workplace from dirt and dust.
5. Bring the container prepared for the oil to the reverse sensor and unscrew it.
6. Try to quickly remove the old ESD and install a new one in its place, then quickly tighten it until it stops.
7. Connect the power wires to the new sensor.
8. Wipe off all remaining oil using a rag.
9. (add oil if necessary) and make sure the new reverse sensor is working.
