How to Test the Quality of a Three-Wire Reversing Radar?

[LaEdward]

The three wires are divided into positive, negative, and one video line. Use a test light to measure the positive and negative poles, and use a multimeter to test the conductivity of the video line. After engaging reverse gear, lightly touch the surface of the radar probe; if there is vibration, it is functioning properly, while no response indicates a fault. More details are as follows: 1. Definition: The reversing radar, also known as the "reverse collision avoidance radar" or "parking assist device," mainly consists of ultrasonic sensors, a controller, and a display. 2. Components: Ultrasonic Sensor: Its primary function is to emit and receive ultrasonic signals, then input the signals into the main unit for display on the display device; Controller: Processes the signals to calculate the distance and orientation between the vehicle and obstacles; Display or Buzzer: When the sensor detects that the distance between the car and an obstacle reaches a dangerous range, the system alerts the driver through the display and buzzer.
