Why is the reverse radar of Corolla Hybrid not working?
2 Answers
The reasons why the reverse radar of Corolla Hybrid is not working are as follows: Radar itself problem: If the reverse radar is not working, first check whether the power cord of the host is properly connected and there is no current, then check whether the radar host line is loose. If there is no problem, the issue may lie with the radar itself. Check the bumper line connection: When the reverse radar is not working, first check whether the bumper line connection is intact, then check whether the reverse light is on when shifting to reverse gear. If not, check whether the reverse light connection switch is disconnected. Check whether the computer displays a fault code: You can check whether the computer displays a fault code. If these items are fine, then check whether there is a problem with the reverse radar itself.
I've been driving a Corolla Hybrid for several years, and the reverse radar not beeping is actually quite common. It needs to be examined from several technical points. First, the radar sensors on the rear bumper can easily get covered with mud or dust, blocking the signal transmission. I usually wipe them carefully with a wet cloth, and they typically recover. Second, a blown fuse—there's a dedicated radar fuse in the car's fuse box. If it blows, the sound stops. The manual has a location diagram, and you can replace it yourself, but it's safer to go to a professional shop. Third, a control module malfunction—the hybrid's low-speed electric drive mode might reduce the module's sensitivity. Check the wiring or have a technician diagnose it. There's also a settings issue—the radar function might have been accidentally turned off in the central control menu. Make sure it's enabled. All these need to be checked step by step; don't rush to reset the system to avoid messing with the wiring. Lastly, the Corolla Hybrid's quiet design sometimes affects radar performance. Consulting a dealership is the most reliable option since reversing safety is no joke.
