What does it mean when the Civic displays 'Check Rear Radar Sensor'?
1 Answers
The Civic displaying 'Check Rear Radar Sensor' likely indicates that one of the radar sensors is not functioning properly. You can turn the key to the second position, shift into reverse, and walk around the radar sensors to identify which one isn't responding by sound. Function of radar sensors: Radar sensors use Frequency Modulated Continuous Wave (FMCW) radar to detect moving or stationary targets. Even under extreme weather conditions, low-frequency radar can clearly detect high-dielectric objects such as cars, trains, trucks, and cargo. In most outdoor applications, high-frequency radar can detect a wider range of objects and is more powerful than ultrasonic sensors. Radar sensors are ideal for collision avoidance in mobile equipment like reach stackers, forklifts, mining vehicles, as well as port machinery such as transport vehicles, loaders, and handling devices. T30R series radar sensors: The T30R sensor is a long-range alternative to ultrasonic sensors, providing more reliable detection and positional feedback in extreme outdoor conditions and other challenging environments. Compared to traditional 24GHz radar sensors, it features a shorter blind zone, higher accuracy, and the ability to detect targets across a wider range.
