What does it mean when the RVM yellow light is on?

RVM stands for Rear Vehicle Monitoring system, which alerts the driver when there is a vehicle in the blind spot during lane changes. A yellow light indicates a malfunction, requiring troubleshooting and timely repair. Below is relevant information about RVM: 1. Working Principle: RVM uses sub-millimeter wave radar installed on the rear bumper to detect vehicles in adjacent lanes and measure the distance to vehicles behind. When a lane change poses a danger, it alerts the driver by flashing indicator lights and sounding an alarm. This system employs 24GHz sub-millimeter wave radar with a wide detection range that is less affected by adverse weather or sunlight, enabling high-precision detection of approaching vehicles from the rear even at high speeds. 2. Purpose: RVM is a system based on safe driving, aiming to reduce accident risks and driving burden. However, each function has its limitations, so drivers should not over-rely on it and must always prioritize safe driving.
I've dealt with many similar cases at the repair shop. The RVM yellow light usually indicates a warning signal from the rearview mirror monitoring system, such as a blind spot detection issue. Common causes include sensors covered by dust, loose wiring, software needing updates, or camera lenses splashed with mud. Ignoring it may lead to complete system failure, increasing risks during lane changes. I recommend owners first clean the sensors around the vehicle body (located near the rear bumper) with a soft cloth. If the light persists, try restarting the vehicle system, and if that doesn't work, use a diagnostic tool to check error codes. Avoid hitting those small corners when parking to help prevent such issues. Poor weather conditions like rain or snow can more easily trigger the yellow light, so developing regular maintenance habits can save a lot of trouble.
