Where is the switch for the Honda CR-V's non-functioning reverse radar?

Honda CR-V's reverse radar alarm switch is located on the control panel on the left side of the vehicle's center console. It is a button marked with a 'P' and a signal symbol. The principle and functions of the reverse radar are introduced as follows. Principle of the reverse radar: The reverse radar emits ultrasonic waves through ultrasonic sensors. When these waves hit an obstacle and reflect back, they are received by the ultrasonic sensors. The controller then calculates the distance to the obstacle based on the time taken for the ultrasonic waves to be emitted and returned. Finally, the buzzer emits a rapid alarm sound to alert the driver. Main functions of the reverse radar: Accurately measure the distance between the rear of the vehicle and the nearest obstacle; when reversing to the limit distance, it can emit a rapid warning sound to remind the driver to brake; it can repeatedly emit a voice warning sound to alert pedestrians.
I also encountered the issue of non-functioning reverse radar when driving my Honda CR-V before, so let me share some experience. The CR-V's reverse radar switch is usually located on the center console or instrument panel area, with the exact position depending on the model year. For example, in my older model, it was a physical button on the left-side control panel near the steering wheel, with an icon resembling radar waves or a reverse symbol. If the radar isn't making any sound, the first thing to check is whether the switch was accidentally turned off. If the switch is on but still not working, the sensors might be dirty or blocked by mud at the rear bumper position—just wipe them clean with a cloth. Next, check if the fuse is blown. The CR-V's fuse box is located inside the toolbox under the driver's seat; find the fuse corresponding to the reverse radar and inspect or replace it if needed. Additionally, system malfunctions or loose wiring often cause the radar to stop working—in such cases, restarting the vehicle or trying a reset via the settings menu might help. The most reliable approach is still to refer to the user manual for specific locations to avoid unnecessary effort.
As a DIY car enthusiast, I've found that the Honda CRV reverse radar switch isn't hidden too deep. In most cases, it's located in the button area near the steering wheel, such as a button marked with a reverse or P symbol on the lower left side of the steering wheel. To confirm if it's on, press it and the indicator light should illuminate. If the radar isn't beeping, first check the switch status. If that doesn't help, inspect whether the fuse is intact—check the fuse box on the left side of the trunk; the reverse radar fuse number is listed in the manual. The sensors are small circular dots positioned on both sides of the rear bumper, and cleaning off dust and dirt with a soft brush is crucial. Additionally, system misconfiguration or software bugs can also cause malfunctions—try resetting by navigating to the radar switch option in the infotainment screen settings menu. If all else fails, disconnecting the battery negative terminal for a few minutes and reconnecting it can refresh the system.
I've been driving a CRV for several years, and sometimes the reverse radar doesn't make any sound, but it's not a big issue. The location of the switch depends on the model. For most newer models, it's the reverse icon button on the control panel to the left of the steering wheel. If you can't find it, try pressing other buttons on the center console or check the switch options in the settings menu. Checking is simple: make sure the radar isn't turned off, and clean the circular sensor positions on the rear bumper. If it doesn't beep, it might be due to too much dust or minor accidental damage to the wiring. I've dealt with it myself—first try wiping the sensors and checking the fuses, and it usually recovers. Always remind everyone to check the radar system during maintenance to avoid turning it into a safety hazard.
