The integral battery in the anti-
theft alarm (DWA) has lost its en-

assurance that the DWA anti-
theft alarm will be operational if
the vehicle's battery is discon-
nected.

Generator power is only just
sufficient to supply all consumers
and charge the battery.
Possible cause:
Too many consumers switched
on. On-board system voltage
tends to drop particularly at low
engine rpm and when the engine
is idling.
When riding at low engine
rpm switch off all consumers
that are not necessary for
road safety (e.g. heated body
warmer or auxiliary headlights).

Generator power is no longer
sufficient to supply all consumers
and charge the battery. In order
to ensure that the engine can
be started and the motorcycle
ridden, the on-board electronics
switch off the electricity supply
to the on-board sockets and the
auxiliary headlights. In extreme
cases the seat heating and the
grip heating might also be shut
down.
