Dynamic Engine Brake Control (Msr) - BMW R 1250 GS Adventure Rider's Manual

If the electronic processor
receives values for the bank
angle that it considers implaus-
ible over a lengthy period, a
dummy value is used for the
bank angle or the DTC function
is switched off. Under these
circumstances the indicator
for a DTC fault shows. Self-
diagnosis has to complete
before fault messages can be
issued.
The BMW Motorrad Traction
Control can shut down auto-
matically under the exceptional
riding conditions outlined be-
low.
Exceptional riding conditions:
Riding for a lengthy period
with the front wheel lifted off
the ground (wheelie).
Rear wheel rotating with the
vehicle held stationary by ap-
plication of the front brake
(burn-out).
Heating up with the motor-
cycle on an auxiliary stand,
in neutral or with a gear en-
gaged.
When riding on a slippery
surface, never snap the throttle
twistgrip fully closed without
pulling the clutch at the same
time. Engine braking torque
can cause the rear wheel to
skid, with a corresponding loss
of stability. The BMW Motorrad
DTC is unable to control a
situation of this nature. With
dynamic engine brake control,
this loss of stability can be
prevented.

How does dynamic engine
brake control work?
The purpose of dynamic en-
gine brake control is to prevent
the unstable riding states that
can be produced by excess-
ive engine braking moment
acting on the rear wheel. De-
pending on the road condition
and riding dynamic, excessive
braking torque can produce
a sharp rise in rear-wheel slip
and impair directional stability.
Dynamic engine brake control
limits this slip at the rear wheel
to a safe mode-dependent and
bank-angle-dependent regu-
lated slip.
Causes for excessive slip at
the rear wheel:
Riding with engine overrun
on a surface with a low coef-
ficient of friction (e.g. wet
leaves).
