Car parking sensors rear and front

Park Distance Control is an auxiliary parking system that is installed in many modern cars. Classical parking aids were passive and consisted of side markers. They helped to orientate when parking. Modern parking aids are active. Ultrasound, radar or cameras and sensors connected with them made parking process much easier. Today there are systems that independently turn steering wheel on the angle you need, so parking process is performed practically automatically. Driver needs just to drive up to free place on the parking and to pedal gas and brake pedal, the rest is done by Park Distance Control.

More complex Park Distance Control is, more difficult is to find faultinesses. In simple systems that consist mainly of distance sensors diagnostics is rather simple. Especial complexity is repair of systems that are equipped with taxing assistant when parking. If you reveal any faultiness, switch Park Distance Control off till you will find out the cause of faulty. Otherwise Park Distance Control’s faultiness may result in damage of your own car or somebody else’s.

If the Park Distance Control fails, level of comfort reduces. But this is not a big problem. It must be repaired in a service centre. It is doubtful whether nonspecialist will find faultiness by himself, because he has no appropriate equipment for diagnostics.

Malfunctions of parktronic

• sensor is functioning incorrectly;
• control unit is broken down;
• short-circuit of wiring;
• membranes are out of service;
• wires are broken or melted.

Signs of Reversing sensors malfunctions

• no warning signals;
• activation of signal of the internal system that detects malfunctions;
• signal switches on when there are no obstacles in the way;
• incorrect assessment of distance to an obstacle;
• rear parktronics are activated when the car is moving forward.

Causes of Parking assist sensor malfunctions

• manufacturing defect;
• control unit works incorrectly;
• sensor tape is soiled or affected by moisture;
• water on printed circuit;
• the part was damaged as a result of mechanical impact;
• component is installed incorrectly;
• ultrasonic sensors are soiled.

Diagnostics

Condition of the electronic unit, which is a part of the system and serves for its control, is required to be checked annually. For this you need to activate parktronic (ignition should be on) and put finger on the membrane. If the part works correctly it will vibrate and crack a little bit. Then you need to check if Reversing sensors is soiled or there is moisture on it. If the sensor is clean and dry, then check wires and the control unit. For wiring diagnostics use a multimeter. To make sure, that the wiring is not short-circuited, take the cover off and make a test using a resistance meter. If the device readings are of zero values, wires are out of service. To determine which sensor is broken exactly, put obstacles in front of each one in turns. The indicator of a broken parktronic will not work. At last, you should check if parking sensor sensitivity is adjusted correctly.

Parking assist sensor repair

If you identify damage correctly, component repair can be accomplished on your own. For this, do the following:

1. clean the tape and the sensor from soiling components and moisture;
2. clean fastening spot of the sensor to the mounting seat;
3. restore circuit integrity in case if it is broken;
4. set sensor sensitivity by adjusting the trimming resistor.

If a Reversing sensors mirror was damaged as the result of mechanical impact, it must be replaced. In this case it is recommended to use experts’ help. Repair cannot delete mechanical defects of the electronic control unit. If they appear, this system component also needs replacement. If the control unit malfunction is a result of moisture impact, it can be repaired. For that you need to choose appropriate microcircuits and replace the broken ones with them. To accomplish repair, turn off the control unit from power source and dry it. With the use of a tester make sure that elements are working, and install them in the place of old microcircuits.
