ABS fault warning light

Drive with caution

What this light means

This light comes on when the ignition is switched on and normally goes out within a few seconds if the anti-lock braking system (ABS) is working correctly. If it stays on or comes back on, the ABS has a fault: normal braking still works, but the anti-lock function does not.

Immediate actions

  1. 1Continue driving to a safe location with extra following distance and gentle braking.
  2. 2Avoid hard braking on wet, icy or loose surfaces since ABS may not intervene.
  3. 3Contact a BYD authorized dealer or service provider for inspection as soon as possible.

What to check

Note whether the brake-system warning light is also on
Avoid hard or emergency braking where possible until checked
Book an inspection with an authorized BYD dealer or service provider

Possible causes

  • Official handbook source: a component monitored by the ABS warning-light system has developed a fault.
  • The handbook does not publish the exact internal fault code or root cause; that requires BYD diagnostic equipment.
