Reverse sensor VAZ-2123 factory 2123-3710410 Automatic device. Wholesale and retail.

1 – side light lamps in the front lights; 2 – fuse block; 3 – external lighting switch; 4 – instrument lighting switch;

5 – indicator lamp for external lighting in the instrument cluster; 6 – license plate lights; 7 – side light lamps in the rear lights; A – to the lighting lamps of the instrument cluster, switches and backlight display.

The parking light is on when the exterior lighting switch is pressed (fully or partially). At the same time, the rear license plate lamps also light up. The interior lamps light up if one of the doors is open or the lamp switch is in the appropriate position. The instrument lighting turns on simultaneously with the exterior lighting. The brightness of the backlight lamps is controlled by the light switch (rheostat) on the instrument panel. The reverse lamps come on when the ignition is turned on and the reverse switch located on the transmission is closed.

To turn on the rear fog lights, there is a corresponding button on the instrument panel. Voltage is supplied through fuse No. 13 (8 A), located in the lower block. The rear fog lights can only be turned on if the exterior lights are on.

Reversing lights are generally not a legal requirement, but they are useful. They serve two main purposes - to warn other road users that you are about to reverse, and to illuminate if you are reversing at night. The circuit is a simple mechanism consisting of one or two rear lights, which are activated using a switch. So if something goes wrong and you find that the reversing lights are not on, it will be quite easy to identify the cause of the failure.

On most cars, the switch is installed on the transmission, and it operates automatically when reverse is engaged. If you or the previous owner of the car made your own adjustments by adding lights yourself, the reverse lights can light up manually. In this case, the switch is most often installed on the dashboard, closer to the driver.

Burnt out lamps

One of the most common problems is a burnt out lamp. To check this, remove the light bulb from the holder and connect it to the battery terminals with a short wire. If the light comes on, then the fault must be looked for at another point in the electrical circuit.

First, check that the light bulb socket and electrical terminals are clean and bright. If there are any signs of corrosion, clean the socket with wet and dry paper, then reinstall the bulb and retest.

A burnt out light bulb is the most common cause

If the reverse light still does not come on, the fuse may have blown. Also, everything indicates a blown fuse if two reversing lights are constantly on. In this case, a replacement will be needed. Fortunately, getting to the fuse box where they are located will not be too difficult for you.

Fuses

In many cases, the fuse protects the reversing lamps and also covers other accessories. If this does not give a positive result, replace the fuse and test again. If after replacement the new fuse melts again, then this indicates a short circuit that has occurred somewhere in the circuit. In this case, you should contact an electrician who can quickly determine the location of the short circuit in the electrical circuit.

If the other fused components are still working, then you need to check the rest of the circuit using a test light.

Basic faults

Below is a list of malfunctions that are typical for the failure of the DSA.

• There is no indication on the dashboard about the vehicle speed;
• Electric power steering does not work;
• There are no increased speeds when coasting;
• Increased fuel consumption;
• Lighting of the “CheckEngine” lamp;

Why does the DSA fail?

There can be many reasons for the failure of a given electrical appliance, but there are several of the same type that occur quite often.

• Oxidation of contacts on the sensor connector;
• Broken sensor power wires;
• Mechanical damage (external and internal);
• Short circuit between contacts on the connector;

If similar signs of malfunction appear on your car or when inspecting the car you notice reasons associated with the failure of the DSA, it must be replaced.

Checking the reverse sensor

It doesn't take too much effort to check your vehicle's reverse sensor (switch). In fact, this process can be completed in several steps.

Step 1: Locate the reverse sensor location. In almost all models it is located at the bottom of the gearbox housing. In fact, there are two sensors installed there: one to measure the speed of movement, and the second is a reverse sensor. To get to it, you will need to drive into the “pit”.

This is what the reverse sensor looks like

Step 2. Once you reach the sensor, disconnect the power wires from it.

Step 3. Connect the disconnected wires to each other (connect them).

Connect the wires together

Step 4. After this, you need to turn on the ignition and “stick” the reverse gear.

DIY replacement instructions

Now let's take a closer look at how the replacement is performed.

Let's consider the procedure using the example of a VAZ 2110 car:

1. First, the car is driven into a pit. The area around the installed device must be cleared of dirt, since after removing the device, all dust and debris will get into the transmission. And this, in turn, can lead to its failure.
2. Next, the crankcase protection is removed; to do this, you will need to unscrew several bolts.
3. Now you will need a small container to collect the oil from the gearbox. When dismantling the DZH, part of the lubricating fluid will come out of the seat, which will subsequently need to be refilled.
4. Disconnect the power connector from the controller and unscrew it from the installation location.
5. Then clean the socket so that the new device can be installed in the seat without any problems. Install the new controller, do not forget the O-ring.
6. Next, you will need to fill the transmission with the required amount of lubricating fluid, that is, what you drained needs to be poured back. But if the lubricant that you collected when removing the DZH contains traces of wear products, for example, metal shavings or sediment, then you need to think about replacing the fluid. Or, at a minimum, you need to fill the box not with collected oil, but with new one.
7. Then all you have to do is reassemble all the elements in the reverse order and check the functionality of the installed DZH.

Checking the electrical wiring

If the current does not reach the lamp socket, you should check the rest of the electrical circuit in reverse order.

1. Check your repair manual for the color and route of the reversing wires.
2. Probe each wire along its entire length.
3. In most cases the wire will disappear into the cable where you can't reach it.
4. In this case, you should be extremely careful, because you risk damaging the working wire.
5. Once you have identified the faulty section of the wire, remove it and install a piece of new wire in its place.

Important! Be sure to provide high-quality insulation at the wire connection points. The quality of the insulation primarily determines the reliability of the contact and the safety of the driver. You can also eliminate the possibility of a short circuit.

When reversing the car, a special white light must be turned on - the reverse switch (sensor) installed on the gearbox is responsible for this. Read the article about what a reverse switch is, how it works and works, as well as about selecting this device and replacing it.

Place of the switch in the light switching circuit

On cars with manual transmission, voltage to the lamps when reversing is supplied through a limit switch (the so-called frog), which is screwed directly into the gearbox housing. When reverse gear is engaged, the switch button is pressed inside the gearbox. The contacts inside the “frog” bridge, and current begins to flow to the lamps.

On the circuit diagram for turning on the reversing lights, we can see that on the VAZ 1118 Kalina, the current from the battery through the ignition switch (No. 2) is supplied to fuse F1. Passing through the fuse that protects the switching circuit, “+” goes to the limit switch (No. 10). The contacts are in a normally open state and close only when reverse gear is engaged. Thus, current begins to flow to the light bulbs. The second contact of the lamps is connected to the “–” battery through the common ground contact of the lamps.

On cars with automatic transmission, the role of the limit switch lies with the selector position sensor. Information about changing the location of the gearshift knob is transmitted to the engine ECU, the light control unit.

How to check the "frog"

1. Remove the headlight switch chip.

2. Turn on the ignition.
3. Using a small piece of wire, connect the contacts of the reverse gear sensor connector to each other.

If the reverse lights are on, then the problem is in the “frog”. Some drivers disassemble the switches, clean the contacts, after which the device continues to work properly. It is up to you to judge the appropriateness of such measures. But keep in mind that on many cars (including VAZ models) the limit switch is located below the oil level in the gearbox. We recommend simply replacing the power sensor. To minimize oil loss, jack up the car on the side where the end switch is installed.

On some cars, the reversing lights do not light up due to incomplete activation of the limit switch. The problem can be solved by installing a thinner washer under the “frog”. To make sure that the switch is working, check with a multimeter in ohmmeter mode whether the contacts close when you press the button.

Checking the circuit

The essence of diagnosing the reason why the reverse lights do not work comes down to identifying the section of the circuit where the voltage is lost. To do this, you can use a regular control light. Continuity testing is done with an ohmmeter, so you need to know how to use a multimeter.

You can start checking directly from the limit switch connector. Turn on the ignition. Connect one contact of the control light to an unpainted metal part in contact with the body, and the second to the “+” connector.

• If power comes in, check the reverse sensor.
• If after installing the “jumper” in the connector the lights do not light up, then the problem is in the section of the wire circuit going from the connector to the lights. Ring the wire to the point where it divides into light bulbs on the left and right sides. Most likely, the reason is the break.

To find the pinout of connectors, light contacts, and wire colors, be sure to study the electrical diagram of your model and vehicle configuration.

The lamps are constantly on

If the lights on your car are constantly on or come on regardless of whether reverse gear is engaged, the cause will be among the following breakdowns:

• short-circuiting the “+” going to the reverse gear sensor and the light bulb wires from the switch;
• the wire going from the connector to the lights has a short to “+” (this happens if the wires in the harness fray);
• The sensor is stuck in a closed state.

5 – indicator lamp for external lighting in the instrument cluster; 6 – license plate lights; 7 – side light lamps in the rear lights; A – to the lighting lamps of the instrument cluster, switches and backlight display.

The parking light is on when the exterior lighting switch is pressed (fully or partially). At the same time, the rear license plate lamps also light up. The interior lamps light up if one of the doors is open or the lamp switch is in the appropriate position. The instrument lighting turns on simultaneously with the exterior lighting. The brightness of the backlight lamps is controlled by the light switch (rheostat) on the instrument panel. The reverse lamps come on when the ignition is turned on and the reverse switch located on the transmission is closed.

To turn on the rear fog lights, there is a corresponding button on the instrument panel. Voltage is supplied through fuse No. 13 (8 A), located in the lower block. The rear fog lights can only be turned on if the exterior lights are on.

Reversing lights are generally not a legal requirement, but they are useful. They serve two main purposes - to warn other road users that you are about to reverse, and to illuminate if you are reversing at night. The circuit is a simple mechanism consisting of one or two rear lights, which are activated using a switch.

If you or the previous owner of the car made your own adjustments by adding lights yourself, the reverse lights can light up manually. In this case, the switch is most often installed on the dashboard, closer to the driver.

How to change the oil in the box

As stated in the regulations, it should be changed every forty-five thousand kilometers, and before that, it is advisable to warm up the car or drive it so that it does not become completely cold and is sufficiently liquid. To make the change you need the following set of tools:

• Special hexagon and preferably twelve
• Any unnecessary container to drain waste
• Any key for seventeen

Engage reverse gear and move away. Then turn off the engine and leave the gear engaged, putting shoes under the wheels and putting the car on the handbrake.

On the overpass, loosen the bolts securing the rocker.

Oxidation of contacts

Quite often it happens that the contacts in the rear lights of the “fourteenth” oxidize, and this leads to an increase in the resistance between the power circuit and the lamp. This problem contributes to non-functioning rear running lights.

This problem can be checked by removing the lamps and inspecting their contacts; if the lamp sockets have characteristic traces of oxidation, they must be cleaned with sandpaper and the lamps reinstalled. After which the lights should work.

Summing up

A reverse light that doesn't come on is just as potentially dangerous a problem as a reverse light that stays on all the time, even when the car is moving forward.

Therefore, such a problem cannot be ignored under any circumstances. Just like installing a flashing brake light for the sake of beauty. It may look impressive, but it confuses drivers significantly.

In some cases, you can find and eliminate the cause yourself. And without any problems. But there are also situations when the best solution is to visit an experienced auto electrician.

Why are Eurobonds issued?

For the same reason as bonds in the currency of your country. This is how issuers attract money, and securities in other currencies expand the circle of potential investors. Eurobonds are issued to attract creditors from among foreigners and non-residents. Eurobonds can be traded on one or more exchanges, but their initial placement is often carried out on a foreign site. Otherwise, this instrument is similar to government and corporate bonds.

Diagram of the passive safety system on the Chevrolet Niva

It is practically no different from other cars. The central unit is the control unit for the passive safety system. In the event of a collision, it receives a signal from the impact sensors, then makes a decision about the deployment of certain airbags. The unit is located under the center console of the car and attached to the body:

To get to it, all this needs to be disassembled. But we most likely won't need it.

It is worth noting that there are airbags on the steering wheel, above the glove compartment and in the seats (side). Depending on the direction of the impact, the desired airbag is deployed.

In addition, there is a seat belt pretensioner that retracts the seat belt at the moment of impact. They use the same squibs that are in the airbag.

Location

The location of the switch or frog largely depends not on the make and model of the car, but on the transmission with which the vehicle is equipped.

If it is a manual transmission, then the switch will be installed directly on the gearbox housing. When reverse gear is engaged, the switch button is pressed, the frog contacts are bridged, and current flows to the rear lights.

As for automatic transmissions, instead of a standard limit switch (frog), a selector position sensor is used. Depending on the change in the position of the automatic transmission handle, the corresponding signal is transmitted to the power unit control unit, which transmits it to the unit that controls the light.

Re: Reverse light on (((Help

When on At ignition, you connect the terminals removed from the frog to each other - the rear lights come on. This means the onboard wiring is fine. You put it on a frog and it lights up. This means it is already turned on. A couple of washers for the frog. does not burn. You turn on the “rear” and it lights up. (the sensitivity of turning on the “frog” is adjusted with washers) Another variant of the problem is in the box, when the rear slider is turned on, it does not reach the frog, they say they screw a self-tapping screw into it, or try to throw the washer out from under the frog, thereby lengthening it and tighten it with sealant, you just have to pull neatly, easily break the threads in the box. The simplest thing is to replace it with a new frog, in case it’s the only problem
