Solutions for a car fuel tank cap that won't open: 1. If the fuel tank cap is stuck or rusted, you can insert a small wooden piece into the gap of the fuel tank cap to pry it open. Remember to pull the fuel tank cap's release switch while prying; 2. If the fuel tank cap cable has come off, you can open the trunk and find a removable inner panel on the side of the fuel tank cap. After opening it, you will see the long cable that operates the fuel tank cap. Pulling it will solve the problem; 3. If the fuel tank cap spring has lost its elasticity, the owner can add a small spring (not too soft or too long) to the protruding rubber pad of the fuel tank to increase the elasticity between the fuel tank cap and the locking device.

What Principle Does the Reversing Radar Utilize?

The principle of the reversing radar system involves the use of ultrasonic signals. Controlled by the microcomputer within the reversing radar host, the signals are emitted and received by the probes. By comparing the signal return time, the system calculates the distance to obstacles and then issues different alarm sounds via the alarm device. Below is a detailed introduction to the reversing radar system: 1. The reversing radar system consists of the reversing radar ECU, the reversing radar buzzer, and several (usually four) reversing radar sensors installed on the (rear) bumper. If a rear camera is installed, it provides an image of the rear area of the vehicle on the navigation screen. 2. When the vehicle is shifted into reverse gear, the reversing radar ECU monitors the area around the rear bumper using ultrasonic sensors. If an object is detected within the monitored area, the audible alarm device in the instrument cluster will sound a warning. The system can detect relatively hard solid obstacles as well as objects like wire mesh and fences. 3. The detection range of the two side sensors covers an area 60cm from the corners of the bumper. When the detected distance is less than 20cm on the sides or less than 30cm directly behind the center, the sound signal will become continuous to prevent a collision with the bumper.
