ing off. If it does not go out after starting off or if it lights up while riding, this indicates a
fault in the ABS. In this case, the ABS is no longer enabled and the wheels may lock during
braking. The brake system itself stays functional; only ABS control is not available.
The ABS warning lamp may also light up if the rotating speeds of the front and rear wheels
differ greatly under extreme riding conditions, for example when making wheelies or if the

is reenabled when the vehicle is switched on again. The ABS warning lamp goes out when
you start off.
