BYD Yellow Warning Lights - ESC fault Warning Light
This warning light comes on when the ignition is on. If electronic stability controller (ESC) functions properly, the light goes out in a few seconds. If the system fails, this warning light turns on again until the system fault is cleared.
If the ESC warning light flashes temporarily while the vehicle is in motion, it indicates the ESC system is working.
When the ESC warning light turns on (with the ABS fault warning light and the parking system fault warning light off), the ESC fails, but the ABS and the braking system continue to operate normally.
When the ESC warning light turns on (with the ABS fault warning light and the parking system fault warning light off), the ESC system does not work. This means the vehicle is extremely unstable at sharp turns or when the driver steers away from obstacles ahead.
A warning light that lights up briefly during operation does not indicate a problem.
