How to park without errors, avoiding an emergency? The question often arises not only among beginners on the road track, but also among experienced motorists. Fear of doing the wrong thing gets in the way, and manufacturers of various useful devices help get rid of it. The installation of parking sensors, the price of which is affordable for most vehicle owners, is of no small assistance. But sometimes the parttronic beeps constantly. How to solve the problem, we will analyze in the article. To begin with, let's define what its essence is.

General concepts

Sensors, speaker and control unit

The risk of not noticing people walking behind the "steel horse" or, even worse, children playing is considerable. In this regard, drivers are wondering: parking sensors - what is it, how to mount it? Parking radar refers to a specially designed device. The idea of ​​its creation was the need for measurements between the car and the parking space in order to make the right maneuver.

For vehicle owners with limitedreview and for beginners, installing parking sensors (its price is acceptable for everyone and is about 1000 rubles) is a mandatory procedure. Sensors, speaker and control unit are the simple basis of a well-thought-out design. The measurement accuracy is dictated by the number of sensors. They are activated when the reverse gear or front brake is engaged when the unit is placed on the front bumper. The ECU is the central link in warning the motorist of the danger of a collision.

About the advantages and disadvantages

Car enthusiasts have already rated the device

Car enthusiasts have already appreciated the device, and it is in demand in the car market. Where is the parking lot located? The answer depends on the brand and the driver himself. The device can be installed on the rear or front bumper. When installed on the front of the vehicle, power comes from the brake pedal, switching on the first speed, from the output to a separate button. Behind it is mounted on a rear-view mirror. The display is installed on the dashboard, which is not to everyone's liking. Some people prefer to do it with a roof lining at the back, as, for example, on the Renault Megan. What can be said about the merits of the device?

  1. Use possible on machines regardless of brand.
  2. Withstands temperatures from -35 to +50 degrees.
  3. Easy to operate, does not require specialized skills. In a metropolis, it contributes to prompt and proper parking.
  4. Provides safety in tight spaces.
  5. Does not lose properties under the influence of dirt, road dust, moisture, increasedtemperature.
  6. Drilling holes will not be useful when referring to electromagnetic radar modifications.

Among the shortcomings, experts note the following:

  • High probability of failures and inaccurate information in the presence of snow, a layer of mud.
  • Failures happen, and the parking sensors constantly beep, forcing the owner of the car to resolve the issue in the service.
  • Rough terrain can cause crashes.
  • To install ultrasonic options, you have to damage the bumper.
  • Not always endowed with a wide coverage angle, forcing the driver to inspect the place himself.

More on how parking sensors work.

The measurement accuracy is dictated by the number of sensors

Highlights of functionality

The system is endowed by the manufacturer with a camera, a transmitter and receiver unit. The video image enters the transmitter unit, which sends data to the receiver. The picture is displayed on the monitor, helping the motorist to park close to other cars, excluding "dead zones", without touching other people's vehicles. The tightness of the rear view cameras, infrared illumination favorably affect parking at night. The best option is a harmonious union of the camera with the electronic system. This is the ability to recognize obstacles when sensors can't cope with this task.

Installation details

parking sensors beep constantly

For installation it is necessary to remove all contents from the luggage compartment. Power can be supplied from the reversing lamp:when the reverse speed is turned on, the radar design is simultaneously turned on. To install the unit, you can use the niche for storing the jack. Power is supplied by a single-core extension cord, which is connected to the “+” of the headlight, insulating the connection. The wire is led to the place of installation of the parking sensors unit. Next, you need to remove a small part of the insulation on the positive wire and attach an extension wire to the power headlight. Good insulation is required. Removing the sealing gum of the trunk, the extension wire is passed under the sheathing material with the output to the installation niche of the unit. The extension wire itself is eventually connected to the “+” of the block. Next, you need four sensors.

The minimum height from the ground to the installation site should be at least 45 cm. For placement on the bumper in some configurations of parking devices, there is a marking ruler, with its help it is easier to fix the sensors by resorting to drilling. Not everyone succeeds in this work, it is better to turn to specialists, because even with the right actions, mistakes occur. Installing parking sensors is not so easy.

Special Radars

Experience shows that the presence of a large number of sensors will ensure high-precision products. Brand models are in trend, so it is recommended to pay attention to the name of the manufacturer, to get acquainted on the forums with the experience of other road users. Special models are offered on the market - parking radars for 8 sensors, expanding visibility by 100%. Some foreign cars already have such a mechanism, so you can’t buy separatelywill be needed. These include options Park Master8FJ-27, Phantom DP 8Z, etc. They provide an LCD display, sound indication in Russian, interesting lighting, a shape that gives a special charm to the car. Models allow you to quickly put vehicles in the parking lot without excesses. Overhead models are available for sale without assistance.

Why does it break?

Functional Highlights

Sometimes the driver is forced to face the fact that the parking sensors are constantly beeping, there may be several reasons for this. The trouble with ultrasonic models is a block. He is responsible for the functioning, unexpectedly failing. The ohmmeter terminals will help identify the problem. It could be a misconfiguration. Sensors often fail. The cause of the malfunctions is the notorious dirt, dust and water in large quantities. A good sensor always vibrates - this is the easiest way to check. Factory marriage is also not excluded. All this leads to breakdowns and repairs.

Common breakdowns of parking sensors

The problem that the parking sensors are constantly beeping is not the only one. With independent installation work, there is a high probability of wiring malfunction, unreliable contact insulation. As a result, the sensor hangs in the air. The result is that it ceases to play its role, gives errors related to measuring the distance to a pole or curb. The unit shows meters, but does not signal or vice versa. It may not recognize the obstacle. All this leads to the service shop.

Repair wisdom

Performing diagnostics dictates the choice of an effective method for correcting defects. In the case when the parking sensors constantly beep, we are talking about contamination of the sensors. It is necessary to inspect them, wipe the sensors with a dry soft cloth. He especially likes to make such sounds on a frosty day or after washing. This happens due to the fact that water enters the sensor, freezes in the cold. Drying the fixture eliminates the need for repairs. To do this, you can put your favorite "swallow" in a heated room.

Setting in this case matters: if the sensors are set incorrectly, you have to deal with an annoyingly stable signal from the device. Beeping or not, the probability of replacing the sensors is close. Do it better in the service. To avoid a reaction to growing grass, you will need to adjust the sensitivity of the devices. A service book, a pair of screwdrivers are eternal companions of self-repair, but it’s better not to do this: the process is time-consuming, not justified. Service station specialists with professional knowledge, a competent approach, and knowledge of the technical condition will figure out what the matter is much faster and find the most effective troubleshooting tactics.
