What's the matter with the front assist system sensor having no data?
4 Answers
Front assist system sensor having no data may be due to a malfunctioning front assist system sensor or issues with the sensor signal circuit. It needs to be checked and repaired at a 4S shop or repair shop using a fault diagnostic tool to resolve the issue.

Possible causes: During heavy rain or on winding mountain roads, there might be no data because the front assist system sensor is constantly working. Long-term radar detection imbalance caused by harsh conditions such as mountain roads and rainy weather may result in undetectable data, leading to a warning that the front assist system sensor has no data.
When I was driving, if the front assist system's sensor showed no data, it could be caused by some common issues. The most common one is the sensor being blocked by dirt. Like the last time I drove on the highway after rain, mud splashes and bugs covered the radar cover, and the system immediately malfunctioned. Just gently wipe it with a soft cloth when cleaning. It could also be due to loose or oxidized wiring connectors, which might happen after driving on rough roads with severe vibrations. If it's an electrical issue, like a blown fuse or unstable voltage, you'll need to check the corresponding position in the fuse box. There could also be software problems—if the car is too old and hasn't had its program updated, it might cause data interruption. It's best to visit a professional shop to read the fault codes to prevent minor issues from turning into major problems. Remember not to disassemble it yourself—the sensor is very delicate.
I usually check the front assist system before driving, and it's really unsettling when the sensors aren't working. The first time it happened was in winter when snow covered the radar, causing all data to disappear. I had to carefully wipe it off with a towel. Another time, it might have been due to aging wiring that was gnawed through by mice—the mechanic said this is common. Sometimes, driving on bumpy roads for too long can loosen the connections, but stopping for a while can restore functionality. From my personal experience, it's important to regularly clean the sensor surfaces and have the wiring thoroughly checked during maintenance. If there's no data at all, the sensor might be broken and need replacement, which can be costly. Safety comes first—if the system fails while driving, pull over immediately and don't push it. Modern cars rely heavily on these devices, so get them fixed promptly if they break.
No sensor data is mostly due to dirt or damage. First, try cleaning the small circular sensor area near the front bumper, but avoid scratching it with hard objects. It could also be caused by unstable connections leading to data loss. I recommend going to a 4S shop for inspection as soon as possible—they have the tools to diagnose the specific issue. Simple problems like a blown fuse can be fixed with a quick replacement. If it's internal damage, you'll need to replace the part. Don't worry too much—most issues can be repaired.
