Why didn't the back-up radar go off?
Reasons for a back-up radar not going off may include wiring problems, faulty sensors, faulty buzzers or displays, low or thin barriers, fuse problems, and other system failures. Here is a detailed explanation of these reasons:
Wiring problems : The wiring of the back-up radar may age, break, or be poorly connected, which can cause the radar to not function properly. Check the wiring for aging, breakage, or poor connections, and replace or repair the wiring if necessary.
sensor failure : The sensor may not function properly due to dirt, damage, or improper installation. Clean the sensor or replace the damaged sensor.
faulty buzzer or display : A damaged buzzer or faulty display can also cause the back-up radar to go silent. Inspect and replace damaged parts.
Too low or too fine : When the obstacle is too low or too fine, the reverse radar may not be able to detect the obstacle and no alarm will be sounded. Get out of the car to check the obstacle and continue to reverse after making sure it is safe.
fuse problem : The power supply fuse of the reversing radar may blow, causing the system to be unable to supply power. Replace the blown fuse.
other system failure : if the above methods can not solve the problem, there may be other faults in the vehicle system, it is recommended to go to the 4S shop or professional maintenance shop for a comprehensive inspection.
Steps typically include checking and repairing wiring problems, cleaning or replacing sensors, checking and replacing buzzers or displays, exiting the vehicle to view obstructions, and replacing blown fuses. If the problem persists, it is recommended to go to a professional repair shop for a full inspection and repair.
How to fix the back-up radar if it doesn't sound?
1, the repair method of reversing radar does not sound is to connect the main line, replace the buzzer, repair the line at the bumper, replace the sensor, turn on the radar. Connect the main cable: Check whether the main cable of the reversing radar is loose, and connect the main cable.
2, in the repair, we first open the trunk, check whether the line is broken. Check the controller, if the water must be burned out, must be replaced, this we can not repair. Turn on the ignition switch, put the reverse gear, if the reverse light is not on, it should be the reverse switch or reverse line fault.
3, reversing radar does not sound the solution is: replace the buzzer or display; Check and connect astern radar lines; Tighten the connection between the buzzer or display and the host. The reason why the astern radar does not sound is that the astern radar line is faulty.
4, in the process of the vehicle near the rear obstacles, if the reversing radar does not sound or there is no relevant information prompt, then the system may fail, we need to check it.
5, when it is found that the reversing radar does not ring, you can first check whether the line connection at the bumper is intact, and then check whether the reversing light is lit when the reverse gear is hung, and if it is not lit, check whether the connection switch of the reversing light is broken.
6. The obstacles detected by the radar are too low and too thin, resulting in radar detection and no sound. The fuse of the back-up radar is loose and falls, causing the radar to not sound. The radar route is faulty, the radar line is aging.
