Why does the car display a radar system malfunction?
3 Answers
Car displays a radar system malfunction due to poor sensor contact. Here is the relevant introduction about the reversing radar: 1. Working principle: The PDC system works by usually installing radar detectors on the rear or front and rear bumpers of the car to detect obstacles in front or behind, helping the driver "see" the obstacles or the distance from other cars when parking. This device not only facilitates parking but also protects the car body from scratches. 2. Function: When reversing, it helps the driver "see" things that are not visible in the rearview mirror, notifying the driver about surrounding obstacles through sound or more intuitive display. It eliminates the troubles caused by the driver looking around when parking, reversing, or starting the vehicle, and helps the driver overcome blind spots and unclear vision, improving driving safety.
With years of experience in car repair, I've found that common causes of automotive radar system failures fall into several categories: sensors covered in mud, snow, or dirt are the top issue, which can usually be resolved with a simple cleaning. Damage to the sensors themselves, such as deformation from impact or aging, can also lead to inaccurate detection and trigger error codes. Wiring problems like loose connections, rust, or short circuits frequently occur, especially after wet weather. Outdated system software needing updates or abnormal connections with mobile phones can cause malfunctions. Other issues include blown fuses, unstable voltage affecting power supply, and interference from aftermarket devices like dash cams. Additionally, calibration deviations require professional readjustment. If you encounter these issues, don't wait—safety first, head to a reputable shop immediately for inspection to avoid rear-end collisions or reversing accidents.
As a car enthusiast, my fellow car lovers and I often discuss the causes of radar malfunctions. External environmental factors have a significant impact—water droplets during rain can block sensor signals, while accumulated snow or dust can trigger false alarms. Another factor is internal aging or damage to the sensors, leading to degraded performance and inaccurate detection. Poor wiring connections, such as loose or worn-out plugs, can cause intermittent issues, especially after car washes when moisture worsens the problem. Software systems that haven’t been updated may report bugs, requiring a vehicle restart. Voltage issues, like an unstable battery, can also be culprits. It’s advisable to regularly check sensor cleanliness and avoid applying films nearby. Address malfunctions promptly—radars are a critical safety barrier for safe driving.
