Why does the Odyssey's reverse radar button light keep flashing?
2 Answers
The reasons why the Odyssey's reverse radar button light keeps flashing may include a blown fuse or a sensor wiring fault. Blown fuse: If the reverse radar fuse is blown, it can cause the light to keep flashing. Locate the corresponding fuse in the car's fuse box and check for any issues. If the fuse is melted, it is recommended to replace it with a new one and try again. Sensor wiring fault: A fault in the reverse radar sensor wiring, such as a loose connection or broken circuit, can also cause this issue. Use a diagnostic tool to detect and troubleshoot the problem. The reverse radar system mainly consists of ultrasonic sensors, a controller, and a display. Any problem in these components could lead to a malfunction.
After repairing cars for so many years, I've encountered many cases of Odyssey's reverse radar button lights flashing. The most common issue is faulty radar sensors, which may be obscured by mud or have poor wiring connections. When the system detects a sensor failure, it will flash the light as a warning. It could also be caused by water ingress short-circuiting the control module, especially after car washes or rainy days. Additionally, aging wiring can cause signal abnormalities. First, check those small black circular sensors at the rear of the vehicle and try cleaning them. If the light still flashes, you'll need to read the fault codes using professional equipment connected to the OBD port to identify which specific sensor is faulty. I recommend not removing the bumper yourself; it's safest to go directly to a 4S shop for inspection, as improper disassembly could affect the vehicle's sealing.
