ESC system fault warning light
What it means
Temporary flashing while moving indicates stability-control intervention. A steady warning can indicate unavailable ESC; this is different from intentionally switching ESC off.
What to do
If ESC, ABS and the brake warning remain on together, immediately stop safely and contact BYD. Arrange authorised inspection for a missing self-check or steady warning during driving. Do not dismiss simultaneous warnings as a routine reset condition.
