ABS Warning Light Always On – 2020 Honda CR-V
The ABS warning light is constantly illuminated on the dashboard, indicating a fault in the anti-lock braking system. While the standard braking system may still function, the ABS and potentially the traction/stability control systems are disabled, which can reduce braking performance in slippery conditions.
