What does the yellow RVM light on an electric vehicle mean?
2 Answers
When the RVM yellow light is illuminated on an electric vehicle, it indicates a malfunction in the Rear Vehicle Monitoring system, and the cause of the fault needs to be identified and repaired promptly. Here is an introduction to the RVM in electric vehicles: 1. RVM Principle: RVM stands for Rear Vehicle Monitoring system, which issues an alert when there is a vehicle in the blind spot during lane changes. 2. RVM Installation: The RVM uses sub-millimeter wave radar installed on the rear bumper to detect vehicles in adjacent lanes and the distance to vehicles behind. When there is a risk due to changing lanes, it alerts the driver by flashing indicator lights and sounding an alarm.
While I was delving into electric vehicles, I noticed a yellow light on the dashboard labeled RVM, which stands for Regenerative Braking System Warning. This system is responsible for converting energy into electricity during deceleration. If the system malfunctions, the yellow light will illuminate, commonly due to sensor failure, loose wiring connections, or software errors. When driving, you might feel uneven braking force and poor energy recovery, which can affect the driving range. My suggestion is not to rush when encountering this situation. Maintain a steady speed, pull over to a safe place, and then contact the manufacturer or a repair shop to read the fault codes for timely resolution to prevent the problem from escalating. When driving an electric vehicle, it's essential to pay attention to system maintenance regularly. Don't wait until the warning light comes on to act—routine checks can prevent issues before they arise.
