Why does the reversing camera keep making abnormal noises?
2 Answers
The main causes and specific solutions for abnormal noises in the reversing camera are as follows: 1. Foreign objects stuck on the reversing radar probe, causing signal blockage. Check if there are any obstructions on the radar holes at the rear of the vehicle. 2. Leakage or seepage of the rear wiper water pipe into the reversing radar system. Seal the leakage point (or replace the pipe) and drain any accumulated water in the radar system. 3. Errors in the radar's ultrasonic signals, leading to false alarms. Restart the engine and try reversing in an open area to observe the effect. 4. Short circuits in the reversing radar wiring or faults in the radar module. Visit a 4S shop or repair shop for inspection and repair, checking the wiring or replacing the radar module.
Recently, I've been hearing a creaking sound from the rearview camera every time I reverse, which is quite annoying. The possible reasons could be that the camera isn't installed securely, with the bracket or screws loosening over time, causing it to wobble and rub against other parts when the car moves. Sometimes, it's due to aging or improperly secured internal wires that rub against the car body on bumpy roads, producing squeaky sounds. In severe cases, this can even lead to short circuits and fires. A friend of mine had this issue—ignored the noise for a while, and the camera eventually stopped working, costing him 500-600 yuan to replace. The simplest solution is to gently press the camera; if the noise reduces, it's likely loose. However, it's best not to disassemble it yourself to avoid accidentally damaging components. I recommend having the bracket and wiring checked during regular maintenance visits. Adding a spacer or securing the wires can easily fix the issue—safe driving is crucial.
