Parkmaster DIY repair

It is sad to realize, but even the best parking sensors can break down. Repairing smart ultrasound equipment is not always within the power of the average motorist. However, anyone can fix simple system failures. Let's consider the most common faults.

If the device immediately emits a sound when you turn on the reverse gear, then there may be several reasons:

• The parking sensor is dirty. In this case, both the emitter itself and the area around it should be cleaned.
• Short circuit in the wiring. Parktronic repair is reduced to the definition of a dangerous (no exaggeration!) Site - "ring" the scheme. And fix the problem.

Everything is simple here! Correct (add or decrease) the sensitivity of the parking sensors and it will regain the "correct" functionality:

• Will warn in time about arising obstacles.
• Stop giving false alarms.

In other words, your absolutely reliable (as you thought until now) device has ceased to see obstacles. First of all, you need to determine which sensor is out of order. To do this, touch the surface of the emitter with your finger and, feeling the vibration in it, go to the next one - everything is all right with that.

After the inoperative source is found, let's try to determine the cause of the malfunction:

• The easiest option is water has entered the sensor... Dry it and forget about the troubles.
• Power outage... Check the integrity of the entire harness and if the chain is broken, restore it. If the circuit is not damaged, then we move on.
• Parktronic control unit has broken (BUP). To eliminate this possibility, switch the wire coming from the inoperative sensor to the adjacent connector. Have a signal? So the BUP needs repair. You cannot cope with this on your own. And even the intervention of specialists does not guarantee success. Most likely, you will need to replace the fully equipped parking sensors. Otherwise (there is still no signal), it’s not the block.
• The sensor is broken. Either a foreign object (for example, a pebble) got into it, or a hidden factory defect manifested itself. There is nothing wrong with that, tk. you can replace a sensor that has already become unusable with a new one (with the same characteristics). Well, you yourself decide to do this or contact the workshop - the question is not a matter of principle.

And in conclusion, I would like to once again emphasize the need to keep all elements of the parking radar clean, since it is pollution that is most often the cause of various breakdowns. And you don't want to be left without your faithful assistants - without parking sensors.

What is parking sensors repair and in what cases is it required?

Not only the metal part of the car, but also other devices tend to wear out and fail over time. Unfortunately, the parking sensors are not deprived of such a fate. A car owner who is used to parking based on information received from sensors will probably upset this circumstance. However, do not despair ahead of time. In this material, we will list the most common types of parktronic breakdowns, describe the probable reasons for the failure of the device, and also offer some tips on how to repair the parktronic with your own hands.

In order to understand what exactly happened, one should recall the principle of operation of the parking sensors. This is nothing more than a radar, which, by means of ultrasonic waves emanating from sensors, informs the driver about the distance to nearby objects.With its help, you can easily park between nearby vehicles without hitting their own car. In this case, if the information does not come to the monitor or is displayed incorrectly, the parking sensors need to be repaired. Which of the elements of the parking system could fail? There are three options. This is mechanical damage to the ultrasonic sensor, a malfunction in the electronic control unit of the car, or a violation of the integrity of the electrical wiring.

Can I repair the parking sensors myself?

A person with experience in carrying out repair work of a similar nature can. At its core, parking sensors repair is not so difficult. The only thing: you must have certain information in the field of radio engineering. It is advisable to know and understand the principle of the parking system functioning. If you know what a closure of an electrical circuit is, are aware of the principle of handling a resistor, have an idea of ​​where the sensors are located and how to replace them, in which case you can proceed with your own repair. Otherwise, we strongly recommend that you seek help from competent specialists who will quickly and inexpensively perform the required work.

Do-it-yourself parking sensors repair or professional help: which is better?

Parktronic is a transceiver device. The purpose of this device is to detect unexpected obstacles in front or behind the vehicle and alert the driver.

Parktronic works on the principle of a radar. That is, the device sends a sound signal in all directions, usually ultrasonic frequencies are used.

The signal, bumping into an obstacle, is reflected from it and returns to the parktronic receiver. In the parktronic control unit, the signal is processed and the driver is warned of an obstacle.

Parktronic is structurally made in three versions:

1. In the first case, it consists of a control unit, sensors, connecting wires.
2. In the second case, the wires are missing.
3. In the third, instead of sensors, a metallized tape is used. It is believed that such tape parking sensors are devoid of dead zones. It is installed on the inside of the bumper.

You can find out about installing parking sensors with your own hands in a practical guide: how to install sensors, equipment and conduct testing.

It doesn't matter what kind of equipment the parking sensors are installed on, on a car or on a warehouse trolley, the malfunctions, in principle, are the same, except perhaps for minor insignificant damages associated with the specifics of the car or trolley.

The system must react to the arising obstacle. If this does not happen, then the first thing to do is to clean the sensors or tape from dirt and moisture. They are very often the causes of malfunctioning of the device.

You also need to clean the places where they are located. That is, the inner part of the bumper under the tape and the sockets in which the sensors are installed. Doesn't help - we examine the transceiver devices.

If there is no damage on the metallized tape, then the cause of the malfunction of the tape parking sensors is in other parts of the device.

When a non-working sensor was identified, then first it should be dried, perhaps moisture has simply got into it. If so, then after drying it will start working normally, if not, we will open it, it is possible that the membrane is damaged, it can be replaced. But it is better to entrust the replacement of the membrane to the master, since such work requires skills.

A malfunction of the parktronic control unit is probably the biggest problem with this device. You can only visually inspect the device on your own and check it for a short circuit. To inspect the printed circuit board of the device, you need to remove the cover.

It is possible that the inspection will also establish the cause of the malfunction, for example, a deposit of dirt or dust, or scale. Scale may indicate that radio components have become unusable, for example, capacitors.

1. The reverse gear is on, and the parking sensors do not give a signal. It is possible that the control unit is not connected to the power supply or is improperly mounted, or the wiring is broken. In this case, we change the connection diagram, restore the integrity of the wiring. Be sure to check if the grounding of the unit is reliable.
2. The distance to the obstacle is determined incorrectly. It is possible that the sensors are dirty. The sensors need to be cleaned.
3. The device often responds to non-existent obstacles. It is possible that the parking sensors are configured for high sensitivity or there is contamination of the sensors. It is necessary to reconfigure the control unit or clean the sensors.
4. Parktronic does not detect any interference at all. It is possible that the device is set to low sensitivity, again the sensors are dirty or the interference is in the so-called dead zone of the parking sensors. You need to either increase the sensitivity of the device, or clean the sensors, rebuild the sensor installation scheme, add, for example, a few more pieces to the existing circuit.
5. The tape parking sensors have the same malfunctions as the parking sensors with sensors. Parktronic tape may be damaged. Malfunctions can also occur when the tape location is dirty. There are malfunctions in the connecting wires and the parktronic control unit. The steps for diagnosing the device and repairing are, in fact, the same as when working with other types of parking sensors.

First of all, you need to follow basic security measures. Sensors, metallized tape, wires, contacts must be regularly inspected, if dirt appears on the sensors and tape, then it must be removed, like moisture.

No moisture or dirt should accumulate under the metallized tape. Therefore, you need to periodically remove it and clean the inside of the bumper.

Dirt can also collect in the control unit, it is worth opening it sometimes and cleaning it from the accumulated dirt and dust inside. Please note that dirt, dust and water are highly conductive and can therefore cause a malfunction.

It is necessary to strictly follow the recommendations and requirements set forth in the parking sensors operating instructions. It is very important to correctly install and select the device, as well as to fine-tune it. You can find out detailed information on choosing a parking sensor in the following detailed article. Compliance with the instructions, correct installation, precise tuning of the parking sensors are the key to its long trouble-free service.

Parktronic or parking radar is a small device that not only makes parking a car easier. It also provides road safety by signaling when an obstacle or other vehicle is too close. And if the parking sensors are broken in the car or the parking sensors simply do not work, then for inexperienced drivers, as well as those who are used to its constant prompts, this can become a real problem.

It is quite simple to determine that the parking sensors have stopped working. If the car has a parking radar installed from the factory, then there is an indicator on the dashboard that will indicate that it is broken. But if you installed the acoustic parking system yourself, then in order to identify a breakdown, you should observe its work. He will either be constantly silent until you hit something, or he will constantly give signals about non-existent obstacles. But to recognize what exactly went out of order is already a little more difficult.

Parktronic malfunctions are often associated with the failure of one of its elements. An acoustic parking system consists of several important components.

1. The control unit is its main part, which is responsible for the operation of the entire system.

It is this element that fails quite often.How to check the functionality of the electronic control unit? You must first disconnect it. Then the ohmmeter terminals should be attached to the conclusions. If the ohmmeter shows nothing, then the cause of the malfunction lies precisely in the electronic control unit. If you are not an electrician and do not have sufficient experience with such mechanisms, it is better not to do parking sensors with your own hands. It is worth contacting specialists here.

Incorrect adjustment of the control unit can also be one of the reasons why the parking radar does not work. If the control unit is configured for high sensitivity, the parking radar will react even to non-existent obstacles. Or the opposite situation, he does not notice the existing obstacles. This may indicate that the sensitivity is too low. And in fact, and in another case, it is necessary to reconfigure the parking radar.

1. Indication devices: a monitor (data on the presence of obstacles and the distance to them are transmitted to it) and a sound warning system (it emits warning signals). These elements fail less often, since they work in the most gentle conditions, inside the car.
2. Sensors or metallized plates are transmission devices that detect the presence of obstacles nearby. In a car, there can be from 2, 4, 6 or even 8. Most often 4 or 6. If 4, then all of them are installed on the rear bumper. If 6 is installed, then 4 of them are on the rear, and 2 on the front bumper. The latter option allows you to control not only the space behind the car, but also in front. The principle of operation of the transfer device is very simple. It sends ultrasonic signals that, when hitting an obstacle, return back. The system reads the round trip time of the signal, thus calculating the distance to the obstacle.

The parktronic monitor fails less often than other elements, as it is located inside the car

Sensors most often fail, because they are the ones most affected by the external environment. They are installed on the bumper of the car, and, accordingly, they can get dirt, snow or water.

How to determine that the parktronic sensor is not working? Simple enough. Start the car and touch the sensor with your finger. A serviceable one always vibrates slightly, and if touched, it should emit a crack. If this was not found, then the reason is precisely in it.

But before you go to a car repair shop, you can try to repair the parking sensor with your own hands. The first thing to do is to clean it, dry it. If, after these manipulations, the system did not work, then the cause of the breakdown may lie in the membrane. In order to identify a malfunction of the membrane, the sensor should be opened. If it is faulty, it must be replaced. However, it is not recommended to change the membrane with your own hands; it is better to entrust this to an auto mechanic.
