Why stop stop signals, reasons how to eliminate. Stop signals do not work, we are looking for reasons and eliminate the malfunction with your own hands

It is difficult to find the driver who denied the fact that the vehicle breakdowns are not much more likely happening in the city where there is a real chance to quickly get qualified help. If something should break, it will happen on the country road, during the departure of nature, where the motorist will remain self-like with the problem. That is why it is recommended to receive any minimum of information on the principles of troubleshooting in the car and the simplest options for eliminating their own hands. One of the most common faults is the problems with electrical wiring and equipment, the work of which is inextricably connected with it, in particular - with the lighting system.

Stop signals, where installed, for which they are intended

In addition to headlights, all vehicles are equipped with special light sources that are called stop signals. They are bright red lights designed to serve a car braking signal.

Stop installation signals are made on passenger and cargo transport, on city electric transport, motorcycles and bicycles. They are turned on automatically, at the moment when the driver presses the brake, and the shutdown occurs when the brake is pressed.

The stop signal is required for installation in any type of transport beyond the railway, on bicycles its installation can be carried out at the request of the owner.

On the car body, the stop signals are placed symmetrically, they should be brighter than the dimensions, during the minimum click on the brake they have to work. To ensure the rapid closure of the electrocups under the brake pedal, a button is installed, a 1 cm pedal is enough to trigger it.

The design of the stop signals can differ significantly, just like at the place of installation, on some cars - they have the form of a scoreboard with the inscription STOP, on other location of their location is a spoiler, on the third, they are equipped with the rear glass of the car.

Interestingly, LED lamps, as such, were first used in the headlights of stop signals.

Stop signals do not work that threatens the car

Non-working stop signals - a breakdown essential, for its reason there may be problems with the safety of the ride, because car drivers moving after your car along the highway, or in a street stream, will not be informed in a timely manner about your braking. As a result, disturbances between vehicles are possible, which is not safe.

If an emergency occurs, the car owner with a faulty stop signal will definitely the culprit of the incident. Employees of the Road Inspectorate will necessarily view a video from the registrar, and it is available today on every car.

Detection on video malfunction Stop signals - irrefutable proof of guilt.

Signal lights on the car body, including stop signals, are very important for the car, which will move along the loaded track or perform any maneuvers.

Overall lights, turning pointers and stop signals are designed to maximize the movement. It is they allowing other drivers to determine the size, the form of the machine and get information about what maneuvers you are going to make.

The driver of the car that goes with a broken stop signal threatens the penalty - for riding on a faulty vehicle.

In addition, the threat of creating emergency will be real - collisions with cars that will move after you.

But it is not difficult to solve the question with the broken stop signal at all, in most cases it is possible to do without attracting car service specialists.

Why stop stop signals, the most common causes

The task of finding faults and identifying their causes is significantly simplified by the fact that they may arise:

as a result, the device breakdowns
in the investigation of violations in the supply system

Stop signals may not be included if:

burned the lamp, one or more,
failed the fuse of the stop signal, or its contacts were oxidized,
i broke the mechanism connecting the stop signal when pressing the brake pedal,
the contacts of the nests intended for the installation of lamps stop signals were oxidized,
there are damaged wires.

Watch the video on how to find a fault:

When studying the reasons, we can conclude that only the last option can cause difficulties, i.e. Wear wear. Lighting the wires, its unsuccessful clamping or bend can cause the stop signals.

In the case of suspicion of the occurrence of this kind of breakage, it will be necessary to find a plan of electrical circuits of auto and armed with a tester. Checking the voltage in the desired sites will help determine the place of defect, finding the problem will need to replace the wire or restore its integrity by soldering.

But it is not worth starting with the search for defects, the reasons are usually simpler. It makes sense to consider them in more detail.

Stop lamp signals how to check how to replace

First of all, it will be necessary to make sure the elementary is the help of light bulbs. This is done as follows: the trunk opens, the rear headlights are removed, as a result, access to stop signals.

On some brands and models, the rear headlight dismantling process may vary, it may be an option when to get to stop signals to remove the headlights do not need.

It is easiest to make sure that the lamps are malfunction by replacing them to new ones. It is not always possible to determine the help of the lamps, so the light-emitting devices are best purchased in advance, about the reserve, if necessary, they can be replaced at any time.

If there are no new suitable lamps, then you can unscrew the lamp from the rotation repeater, the overall fire, other lighting devices of the car. Installing an extracted lamp extracted from another device and knowing the correctness of your assumption. Those. To eliminate the malfunction of the stop signals, you will only need to purchase new lamps and install them.

We watch the video on how to install a stop light lamp:

The experienced drivers are recommended to replace the lamps at the same time, in some models there are automatic synchronous shutdown of both instruments in the presence of a malfunction.

Those. Make sure that the breakdown is diagnosed correctly only if both lamps are replaced.

Contact Stop signals how to check how to eliminate

If the paws are replaced with new, but the fault remains unreasonable, it will be necessary to make sure that the cartridges of the signals are not oxidized. At the same time, you should make sure that the contact of the cartridges with automotive wiring is available.

If, during the inspection, suspicions were available in the presence of high-quality contact - it is better to immediately disconnect the contacts, handle from fine sandpaper, then with electrically conductive lubricant and gently restore the connection.

When checking the contacts, you should use new, or at least other lamps, the option is not excluded that the lamps can be distilled as a result of damage to the contact.

Stop fuses stop signals, how to determine and how to replace

Frequent causes of malfunctions of the power supply of the car are becoming failed fuses. Methods for their verification there are several, it is possible to make it using a multi-mode or visual viewing.

There is another rather simple way to check the stop signal fuse. We must start the car and click Clockson. No sound means that the reason is defined correctly. Required using fuse block diagram to find the one that is responsible for the operation stop signal and the horn, then - perform the replacement.

If it works, the fault is caused by some other causes.

But this method is not suitable for all models of the car, in the electrical panels of some brands it is provided for the installation of individual fuses for Classone and for a stop signal.

Frog sensitive, brake lights switch, where installed, how to check how to eliminate

When you press the brake pedal, the mechanism is transmitted, which is called a confusion or a frog. This mechanism provides on or off stop signals. Naturally, when breakdown, the inclusion of brake lights will not happen.

The reasons for the failure of the frog confusion may be two:

oxidized contacts
corrosion or Nagar on contacts.

These malfunctions are sufficiently similar to each other, eliminate them will require the execution of identical actions: Contacts will need to carefully clean it, if this fails, it will not be possible to replace the limit.

To dismantle the stop signal switch, remove the brake pedals, the switch is located under them and detect at all difficult. To dismantle the terminal, it will be necessary to perform its rotation 90 degrees. Next, you will need to disconnect the wires and somnight from manually. If the stop signal will light up - it is uniquely required to restore the old switch or buy a new one.

If there is a desire to repair the end of the confusion with your own hands, then it is not difficult to do it. At first it will take it to disassemble, wipe the contacts with alcohol, apply a conductive lubricant on them. Then the confusion can be collected, set to place, test.

How to replace a confusion - on video:

Why constantly burn stop signals, how to find and eliminate the cause

To correct the breakdown, which is that the stop signals are lit without turning off, it will be necessary to check the status of the confusion. The breakdown in the oxidation of the contacts can be fixed independently.

If something more serious happened, for example, the spring flew out, then it is better to refer to the specialists in the car service - in this case it will be necessary to replace the broken part.

Troubles in wiring, how to check the wiring, how to troubleshoot

Fully diagnose the power supply of the car in the event that there is special equipment. On the road, naturally, it will have to do easier methods.

The first thing you need to do - to inspect electrical circuit accessible areas, which are located under the hood. Fault may occur between the two wires or on the housing. If there was a breakdown between the wires - they will be melted insulation, such sites can see with the naked eye.

Determine the cause of fault in such a way difficult, but to draw a conclusion as to which areas are in need of diagnosis is quite real.

Also need to check the fuses in the case of a fault, they quickly burn out and thus ensure the safety of all devices connected to this line.

Every vehicle is equipped with a special mini-unit designed to accommodate fuses, required to inspect all-just remove the lid.

To test if the fuse is desirable to use the meter, by visual inspection may be difficult to determine the integrity of the conductive yarn.

All work should be with the ignition off.

Check each circuit breaker - it may be that a few blown. To perform the work time required little, about a quarter of an hour. If the fuse is OK - the resistance will be equal to "0".

If you do find a blown fuse, put on the new one is not recommended - it could suffer the same fate.

Helpful Hint - as fuses, used in automotive electrical circuit differ in the face value, then removing them should lay alternately, it is desirable - not on a slippery surface.

Before performing the test circuits to short-circuit a lot of need to disable. As a diagnostic tool can be used for light or multimeter 12 with soldered wires, the first of which is attached to the cap, the second - the central contact. For the best experience to the ends of the wires are soldered pins of copper wire, they dress PVC tube as an insulator.

Checking is performed after the ignition key is in the first position. Copper probes are applied alternately to the terminals of fuse holders, ie bulb will replace the fuse test. Glow light bulbs means that there is short-circuit in the wiring line. Similar actions are performed when checking the multimeter.

For further action to give specific recommendations difficult, because the electrical circuits of different brands and models have significant differences.

Operation is as follows:

To detect the cause of the CW, view according to the scheme, which electricity consumers are included in the defective chain.
Disconnecting them alternately, it is possible to determine whether the reason is in any of them.
If the search is not effective - the reason is in the wire itself. It will be necessary to disconnect from one end, replace the new one, with the same cross section.
If the KZ is eliminated means the search turned out to be successful.

In order not to bother with a harness, the new wire can be paved on top of the swing. Such a temporary connection can be left, but it is better to contact the service center with a request to perform the overhaul of the wiring of the car - it will be more reliable.

Tips Prof.

To quickly eliminate the malfunction, which will be found during the trip, can be entered as follows: If the breakage concerns the power supply device of the electricity that does not affect the safety of motion, then you can temporarily disable the problematic device.

The circumstances should be taken into account - the range of the upcoming trips and the importance of the device.

Experienced motorists recommend always to have a power supply network with them. It will be needed even if you seek help to professionals, because as a result of constant improvement of the design of cars, there may be differences in the schemes of various series of the same model range.

The scheme is an excellent information source that will help determine the algorithm of actions, will give a prompt which chains need a transclon, which fuses should be paid first.

Another useful advice: Going on the road take with me technical documentation, experience shows that it can be necessary at any time of the trip.

It will not be superfluous in the car except for elementary tools, a control light and a multimeter.
