Both do not burn, I thought the bulbs were burned out or the wires might not be tucked in: I checked - the bulbs are normal (the spiral is whole), the wires also fit where they need to. What could be the reason?
Re: Frog? I mean, the reversing light switch failed.
Or they forgot to put a wire on it, for example ... It happened to me in one service: they forgot to fasten a wire on it, but I thought it flew. ;)
Or maybe they just rotted away ... the tips on the frog
Re: Reversing lights not working. What is the reason?
Hi Zhenya!
It turns out so that if not CHY, then a frog. The point is that one of the pins of the connector is always positive. Therefore, it oxidizes and falls off. Look at the connector. Another option is fuse number 5 (F16), but then the wipers would not work and the turn signals and a bunch of other things ...
Re: Re: Reversing lights not working. What is the reason?
Hello! Thanks, I'll take a look. The fuse means in order. wipers and turn signals work.
Where is this frog on the box?
There is nothing in the book, and I did not find anything on the Internet. Will it be possible to change it without a hole in the conditions "on the street"?
Wow....
Oh Lord, bless this man! He doesn't know where the frog is!
She is at the checkpoint, on the left along the way, below. It sticks out towards the left wheel. It has two wires going to it. You can see on the ground. It is enough to remove the piece of iron that hangs under the engine. Or maybe it is, I don't remember.
If you decide to change the frog, keep in mind - oil will flow.
Yes, I am like this...
Misha, how do I know where it is, if earlier I repaired only a bicycle myself :-) and even then a Soviet one without a gearbox. So you have to ask stupid questions. And since there is no one else to ask them (I have no relatives in St. Petersburg, and so far I’m the only one from my friends on the car), then I have to decide everything through this conf. THANK YOU gentlemen for your answers. ... And I think there will still be a lot of questions, but I'm trying to understand little by little the device of this complex mechanism :-)))
Re: Yes I am...
It's not bad when there is a conf. It’s even better when you don’t mind spending 100 rubles and buying a Talmud for your car. Even if you look only at pictures at night, you can study the car in a week, and if you also read the text, then in a month you can learn how to adjust the carb.

I have three books...
Two devices, and one - minor repairs. Maybe, of course, I didn’t search well, but I didn’t find anything like that there (I’ll look again). One book is specially at home and I read it last night, so I try to match. And then the theory is very good, but practice is better - and I don’t have enough of it ... that’s why I consult with you.
Re: I have 3 books...
And the practice just consists in comparing what is drawn in the picture and what is in the hardware. I don’t believe that the switch for the ZX lights was missing in the picture. Yes, not the gods will burn the pots, you will learn.
The pedestrian is always right as long as he is alive...

Before changing the frog, ring it.
To do this, pull the wires off the frog and measure the resistance of the frog in the "reverse" position and any other position with an ohmmeter. In the "reverse" position, the ohmmeter should show a short circuit (0 ohms), and with the reverse gear turned off, it will show a break (infinity). In this case, the frog is working, and the problem is in the wiring ..
The second option is to short-circuit the wires going to the frog. If the lights come on when the ignition is on, it's a frog. Did not light up - in the wiring.

A reversing light, although it does not belong to the category of mandatory lighting devices, is nevertheless of great importance for the safe movement of your car.
Reversing lamp - main functions
It is quite difficult to imagine how you can drive and not use reverse, or rather, such a situation, in principle, cannot be. Moreover, it is not always possible to move only during daylight hours, when there is excellent visibility outside the window. Therefore, it is very important to ensure maximum comfort for yourself in the evening, as well as at night, and sometimes during the day, during fog, rain and other vagaries of the weather, which do not affect your visibility to other road users in the best way.
Thus, the main function of these lights is to illuminate the roadway when reversing. In addition, they are the ones who warn all participants that you are planning to reverse, thereby performing an informative function. But, unfortunately, sometimes it is necessary to install an additional reversing light, since the standard one is not able to perform all tasks at the required level.
Reversing lights do not work - possible malfunctions and their causes
In order to assess the condition of the flashlight and understand the cause of possible problems, you should study the device and the principle of operation. The scheme of work is quite simple and is as follows. As soon as reverse gear is engaged, a special switch ball, leaving the stem, closes the contacts. Thus, voltage is supplied to the lantern, and it ignites. After the driver turns off the reverse gear, everything returns to its place, and the contacts open under the action of the return spring.
From the foregoing, it becomes clear that these lighting devices, however, like all the others, are connected with the electrical part, which means that there can be a lot of reasons why the reversing lights do not work. Among them, the most common are:
- burned out light bulb;
- contact oxidation;
- failed fuses;
- lack of "mass" on the board;
- the reverse sensor has broken, or its wires have broken;
- the contacts on the headlight film burned out.
Reversing lights do not light - troubleshooting and repair
In general, the result of such malfunctions is the same - the reversing lights do not light up. Then you need to identify the cause and, accordingly, eliminate it. If the lamp burned out, then it is time to replace it with a new one. To do this, by turning off the external lights, open the trunk and disconnect the wiring block. Of course, you will first have to dismantle all the upholstery located behind the lantern. Further, by squeezing the latches located on the sides, you can remove the panel and, by pressing on the lamp itself, unscrew it. After we put a new one and return everything to its place.
To work with wiring, as a rule, a multimeter is required, and a car is no exception.
Oxidized contacts must be cleaned. To provide access to them, you simply need to remove the headlight assembly. What about the missing "mass", so it should be put in place, and the broken wires are called, and the non-working ones are changed. Failed fuses also need to be replaced, they are all located in a special fuse box, so this is not difficult to do. Another problem may also arise when the reversing lights are constantly on.
There may be several reasons for this behavior, or again, not everything is in order with the electrical part, or a special sensor located on the box has failed. In the first and second cases, arrange for the replacement of defective parts. In addition, the reversing light switch may also fail. You can get to it either from the bottom of the car, or through the engine compartment, but, before dismantling it, make sure that it is he who is out of order.
To do this, after releasing it, you need to start the car and, and then, after closing the contacts, look at the lights that should light up. Next, removing the switch, we check with a multimeter whether the contacts close when it is turned on. In the absence of such a closure, flaring is indispensable. Having cut out a flexible contact from the electromagnetic relay of the required length, we tin it in place of the old one. Then, after checking the reliability of the soldering, we assemble the switch back and call. With a normal circuit, we install it in its original place.
String(10) "error stat"
Every motorist, most likely, is aware that one of his most important duties when driving on public roads is to notify other road users of the intention to make this or that maneuver. For example, to indicate the desire to turn left or right, special indicators are used, controlled by a special lever.
However, progress does not stand still, and some warning signals are given automatically by the machine. A vivid example of this is the reverse gear of the car, during the implementation of which the taillights of white-moon color light up automatically and in advance. This happens due to the presence of a special sensor in the design of the car. It is about the principles of its operation and repair that we will talk in the article below.
The device and principles of operation of the sensor
Reversing is one of the most important features available for any car. It is the inclusion of reverse gear that allows the car to move back without using a 180-degree turn. Thanks to this possibility, the driver can not only be conveniently located in parking areas while driving, but also significantly save his time when performing a number of maneuvers.
When reversing, it is important for a motorist not only to closely monitor compliance with traffic rules and control the location of objects standing behind, but also to be sure that each third-party traffic participant is aware of the desire on his part to move in reverse. Fortunately for all motorists, the notification process in this regard is fully automated and occurs through the use of a reverse sensor installed directly in the vehicle structure. Given such an important function of this component of the car, each car owner must monitor its good condition and, if necessary, repair it.
The reverse gear sensor works according to a simple principle, the essence of which is as follows:
- The motorist, wishing to move in the opposite direction, includes a reverse gear;
- The gearshift lever, reaching a certain place, switches the switch / switch (sensor) of the reverse headlights to the “ON” position and they, respectively, light up;
- After the maneuver is completed, the driver changes the reverse gear to first or neutral, which turns off the previously turned on headlights.
The electrical circuit of the reverse sensor is quite simple, if not primitive. Its operation, as a rule, is based on the use of a limit switch, which is some kind of button located on the path of the gearshift lever along the path of the reverse speed and is pressed / pressed when it is turned on / off. That is, when wondering how to change the reverse sensor, you should be prepared for a partial disassembly of the gearbox, because this unit is installed in it or within its operation.
Possible malfunctions
Repair of the reverse sensor is perhaps exactly what no one is immune from. It happens that the node needs to be replaced only for the reason that it simply does not work. How to act in such a situation? First of all, it is important to understand why the sensor is faulty or does not work correctly.
To date, it is customary to single out the following possible node malfunctions:
- there was an oxidation of the contacts in some place of the electronic circuit;
- the sensor is “loose” or out of order;
- there was a "breakdown" in the electrical circuit of the identifier;
- the contact of the sensor and the mounting block is broken;
- its fuse has blown;
- burned out taillight bulbs ("stop").
The symptomatology of a malfunction of the reverse sensor is probably clear to everyone - the corresponding headlights are inoperative or function extremely incorrectly. It is simply unacceptable to operate a car in this state, therefore, first of all, if a problem with a node occurs, you should think about where the reverse sensor is located and how to properly repair it. We will talk about this in more detail below.
Sensor repair: replacement and fault diagnosis
A complete replacement of the reverse sensor is definitely not something that should be done first if the “stoppers” do not work properly. Before dismantling the old assembly and installing a new one, it is important to exclude the possibility of manual repair of the chain and only then resort to replacement. In a typical case, the procedure for repairing a sensor looks like this:
Note that in most cases, the repair of the car's reverse sensor ends either at the first or at the second step of the repair. Considering the absolute simplicity of repair measures, it is only necessary to carry them out correctly and in due measure, then there will certainly not be any problems with the discomfort node.
Perhaps the most important information on the subject under consideration has come to an end. We hope that today's material has answered your questions. Good luck on the roads and in the repair!

The KamAZ stop signal circuit is somewhat more complicated than that of other cars. This is due to the use of several sensors that ensure the inclusion of brake lights when several brake systems are operating. Although the brake system is called KAMAZ, it is now used on other cars due to its reliability. The circuit diagram for all such cars is identical and differs only in design. The KamAZ stop signal circuit includes sensors, an intermediate relay, a buzzer and a parking brake warning lamp, and of course signal lamps in the rear lights of the tractor and trailer. The sensors are installed on the circuits of the brake system in the area of the brake valve and are triggered when the pressure in the circuit changes. On the latest models, a push-button switch mounted under the pedal is used as a brake light sensor, as is the case on most cars. When the pressure changes in any of the circuits, and in the presence of a push-button switch, when you press the pedal, the sensor contacts close and connect the winding of the intermediate relay to the vehicle ground.
In this case, the current from the fuse passes through the relay winding, the contacts of one of the sensors to the car body. The relay contacts close and energize the signal lamps in the rear lights. When the parking brake is applied, in addition to the signal lamps, the parking brake warning lamp flashes. This is due to the fact that the parking brake interrupter and the control lamp receive a minus through the parking brake sensor. Since all the sensors are connected to the intermediate relay coil, when any sensor is closed, a minus appears on all sensors. In order for the control lamp not to turn on when other sensors are triggered, a diode is included in the circuit, which prevents minus from entering the parking brake sensor wire. During operation, some malfunctions are possible. The most common, for all vehicles, is when the brake lights are off. In this case, it is necessary to check whether the lamps are on when the parking brake is applied or not. If the lamps are on, then the sensor is faulty or the wire from it to the relay is broken. To check, it is necessary to disconnect the wire from the sensor and connect it to the vehicle ground. If the signal lamps light up, the sensor is faulty. Otherwise, there is a break in the wire. If the lamps do not light up when applying the parking brake, then it is necessary to check the fuse, signal lamps and relay. Defective elements must be replaced. The cause of the malfunction may also be a broken wire connecting the relay to the signal lamps. If the signal lamps are lit when the brake pedal is pressed, but do not light when the parking brake is applied, then it is necessary to check the sensor, connecting wire and diode for proper operation. It is better to start by checking the diode, which is located on the instrument panel warning lights board, near the parking brake control paw. If, when applying the parking brake, a minus appears on the diode, then the sensor and the connecting wire are working. Otherwise, disconnect the wire from the sensor and connect it to the vehicle ground. If the minus does not appear on the diode, then it is necessary to eliminate the break in the wire, if it appears, change the sensor. Another problem is when the warning lights are constantly on. Unlike those described earlier, this is typical only for the KamAZ stop signal. There may be several reasons. The first is the shorting of the positive wire to the wire of signal lamps, in practice it occurs if the wiring was melted in the process of closing the positive wire to the vehicle ground. The second reason is the sticking of the signal lamp relay contacts. To check, just remove and put the relay back into the socket. If the relay is in good condition, a characteristic click will be heard. A defective relay must be replaced. A third reason may be the lack of power to the parking brake warning lamp and its breaker relay. In this case, the plus through the relay winding of the signal lamps, the parking brake control lamp, the power wire of the control lamp and through one of the consumers, which is powered by the same wire, gets to minus. This closes the circuit and activates the signal lamp relay. To check, it is enough to disconnect the supply wire from the control lamp breaker. The relay should open and the signal lamps should go out. Possible causes could be a faulty fuse or a broken wire. The last reason is the connection of any wire from the sensors to the mass of the car. As with all cars in the KamAZ stop signal, it is also possible that the signal lamp fuse blows. Troubleshooting depends on the moment the fuse blows. To search, you must remove the parking brake and release the brake pedal. If the fuse blows immediately upon installation, then a short circuit must be sought under the instrument panel from the fuse to the signal lamp relay. If the fuse blows when the brake pedal is pressed, there is a short in the wire from the relay to the rear lights or in the trailer socket.
