for a lengthy period the ASC
6
function is deactivated for safety
reasons and an ASC fault mes-
88
sage is issued. Self-diagnosis
has to complete before fault
messages can be issued.
The BMW Motorrad ASC can
shut down automatically under
the exceptional riding conditions
outlined below.
Exceptional riding
conditions:
Riding for a lengthy period with
the rear wheel lifted off the
ground (wheelie) with ASC de-
activated
Rear wheel rotating with the
z
vehicle held stationary by ap-
plying the front brake (burn-
out)
Heating up with the motorcycle
on the centre stand or an auxil-
iary stand, engine idling or with
a gear engaged
Accelerating the motorcycle to
a speed in excess of 5 km/h
after switching the ignition off
and then on again reactivates the
ASC.
If the front wheel lifts clear of the
ground under severe accelera-
tion, the ASC reduces engine
torque until the front wheel re-
gains contact with the ground.
Under these circumstances,
BMW Motorrad recommends
rolling the throttle slightly closed
so as to restore stability with the
least possible delay.
When riding on a slippery sur-
face, never snap the throttle
twistgrip fully closed without
pulling the clutch at the same
time. Engine braking torque can
cause the rear wheel to lock, with
a corresponding loss of stability.
The BMW Motorrad ASC is un-
able to control a situation of this
nature.
