ESC (electronic stability control) fault warning light

Drive with caution

Safety warning — do not ignore this light

This warning light indicates a potentially serious fault. Do not continue driving. Stop in a safe location and contact an authorized service center or roadside assistance. Never attempt to inspect high-voltage or safety-critical components yourself.

What this light means

This light comes on when the ignition is switched on and normally goes out within a few seconds if electronic stability control (ESC) is functioning properly. If it stays on, the ESC has failed, though the ABS and normal braking system continue to operate.

Immediate actions

1Drive more cautiously, especially in corners, wet weather or on loose surfaces, since stability assistance is unavailable.
2Contact a BYD authorized dealer or service provider for inspection.

What to check

Confirm whether the light is flashing briefly (normal operation) or staying solidly on (fault)

Reduce speed in corners and on slippery surfaces until checked

Book an inspection with an authorized BYD dealer or service provider

Possible causes

›Official handbook source: a component monitored by the ESC warning-light system has developed a fault.
›Momentary flashing while driving is normal and indicates the ESC system is actively working, not a fault.
