The ABS warning lamp must light up after the ignition is
switched on and go out after starting off. If it does not go out
after starting off or if it lights up while riding, this indicates a
malfunction in the antilock brake system. 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 con-
ditions, for example when making "wheelies" or if the rear wheel
spins. This causes the ABS to switch off.
To reactivate the ABS, stop the vehicle and switch off the ignition.
The ABS is reactivated when the vehicle is switched on again. The
ABS warning lamp goes out after starting off.
