2007 BMW MOTORRAD K 1200 GT sensor

Ambient temperatureWhen the motorcycle is at a
standstill the heat of the engine
can falsify ambient-temperature
reading1. If the effect of the en-
gine's heat becomes excessive,--
temporarily appears on the
display.
If ambient temperature
drops below 3 °C a warn-
ing appears, drawing your atten-
tion to the risk of black ice form-
ing. The display automatically
switches from any other mode
to the temperature reading when the temperature drops below this
threshold for the first time.
RangeThe description of the residual-
range function ( 50) also cov-
ers the range readout. You can
also view range
1before the fuel
level drops to reserve. A special
average-consumption figure is
used to calculate range; this fig-
ure is not necessarily the same
as the value you can call up for
viewing on the display.
When the motorcycle is propped
on its side stand the slight angle
of inclination means that the sensor cannot register the fuel
level correctly. This is the reason
why the range is calculated only
when the motorcycle is on the
move.
When refuelling after running on
reserve, make sure that you top
up the tank to a level above re-
serve, as otherwise the sensor
will not be able to register the
new level. If the sensor cannot
register the new level neither the
fuel-level reading nor the range
readout can be updated.
The calculated range is only
an approximate reading.
Consequently, BMW Motorrad
recommends that you should not
try to use the full range before
refuelling.
452zOperation

Oil levelOil-level indicator1gives you
an indication of the engine oil
level. You can call up this read-
ing only when the motorcycle is
at a standstill.
The preconditions for the oil level
check are as follows:
Engine at operating temperat-
ure.
Engine idling for at least 30
seconds.
Side stand retracted.
Make sure the motorcycle is
upright. The readings mean:
Oil level is correct
Check the oil level with the
dipstick the next time you
stop for fuel. If you call up anoth-
er reading on the on-board com-
puter, this symbol remains visible
until the sensor again registers a
correct oil level.
Oil level cannot be meas-
ured (conditions as stated
above not satisfied).
The most recently measured
level is displayed for 5 seconds
when you next switch on the ig-
nition.
The oil sensor might be
defective if the "Check
oil level" message reappears
even though the oil level in the
oil sight glass is correct. In this
case, consult your authorised
BMW Motorrad dealer.

ABS self-diagnosisBMW Motorrad Integral ABS per-
forms self-diagnosis to ensure
its operability. Self-diagnosis is
performed automatically when
you switch on the ignition. The
motorcycle has to move forward
at a speed above 5 km/h for the
wheel sensors to be tested.
Phase 1Test of the diagnosis-compat-
ible system components with
the motorcycle at a standstill. ABS warning light flashes.
Possible national variant of
the ABS warning light.
Phase 2 Test of the wheel sensors as
the motorcycle pulls away from
rest. ABS warning light flashes.
Possible national variant of
the ABS warning light.
ABS self-diagnosis
completed The ABS warning light goes
out.
If an indicator showing an ABS
fault appears when ABS self-dia-
gnosis completes:
You can continue to ride. Bear
in mind that neither the ABS
function nor the integral brak-
ing function is available.
Have the fault rectified as
quickly as possible by a
specialist workshop, preferably
an authorised BMW Motorrad
dealer.
ASC self-diagnosis
OE
BMW Motorrad ASC performs
self-diagnosis to ensure its op- erability. Self-diagnosis is per-
formed automatically when you
switch on the ignition. The en-
gine must be running and the
motorcycle must reach a speed
of at least 5 km/h in order for
ASC self-diagnosis to complete.
Phase 1
Test of the diagnosis-compat-
ible system components with
the motorcycle at a standstill. ASC warning light slow-
flashes.
Phase 2 Test of the diagnosis-compat-
ible system components while
the motorcycle is on the move. ASC warning light slow-
flashes.
ASC self-diagnosis
completed The ASC warning light goes
out.
582zRiding

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 BWM Motorrad ASC is un-
able to control a situation of this
nature.
Tyre pressure
monitoring RDC
OE
FunctionA sensor integrated into each
tyre measures the air temperat-
ure and the air pressure inside
the tyre and transmits this in-
formation to the control unit.
Each sensor has a centrifugal-
force tripswitch that does not
enable transmission of the meas-
ured values until the motorcycle
has accelerated to about 30 km/
h. The display shows
--
for
each tyre until the tyre-pressure
signal is received for the first
time. The sensors continue to
transmit the measured-value sig-
nals for approximately 15 minutes
after the motorcycle comes to a
stop.
The control unit can adminis-
trate four sensors, so two dif-
ferent sets of wheels with RDC
sensors can be alternated on the motorcycle. An error mes-
sage is issued if wheels without
sensors are fitted to a motorcycle
equipped with an RDC control
unit.
Temperature
compensationThe tyre-pressure readings
shown by the multifunction
display are temperature-
compensated; the reference tyre
temperature for these readings
is always 20 °C. The air lines
available to the public in petrol
stations and motorway service
areas almost invariably show
temperature-dependent tyre
pressures, so in most instances
these gauge readings will not
tally with the readings shown by
the multifunction display.

RimsVisual inspectionMake sure the ground is level
and firm and place the motor-
cycle on its stand.
Visually inspect the rims for
defects.
Have damaged rims checked
and, if necessary, replaced by a
specialist workshop, preferably
an authorised BMW Motorrad
dealer.WheelsRecommended tyresFor each size of tyre BMW Mo-
torrad tests certain makes, and
approves those that it certifies
as roadworthy. If BMW Motorrad
has not approved the wheels and
tyres, it cannot assess their suit-
ability or provide any guarantee
of road safety.Use only wheels and tyres ap-
proved by BMW Motorrad for
your type of motorcycle.
You can obtain detailed informa-
tion from your authorised BMW
Motorrad dealer or on the Inter-
net at www.bmw-motorrad.com.
RDC label
OE
Incorrect tyre-removal pro-
cedures can result in dam-
age to the RDC sensors.
Be sure to notify the authorised
BMW Motorrad dealer or spe-
cialist workshop that the wheel is
fitted with an RDC sensor. If the motorcycle is equipped
with RDC, each wheel rim bears
an adhesive label indicating the
position of the RDC sensor.
When changing the tyre, take
care not to damage the RDC
sensor. Be sure to draw the
attention of the authorised BMW
Motorrad dealer or specialist
workshop to the fact that the
wheel is fitted with an RDC
sensor.
Remove the front wheelMake sure the ground is level
and firm and place the motor-
cycle on its centre stand.

Remove screws1on left and
right.
Pull the front mudguard for-
ward to remove. Once the calipers have
been removed, there is
a risk of the brake pads being
pressed together to the extent
that they cannot be slipped back
over the brake disc on reas-
sembly.
Do not operate the handbrake
lever when the brake calipers
have been removed.
Remove securing screws 2of
the left and right brake calipers. Force the brake pads slightly
apart by rocking brake
calipers

against brake discs 4.
Mask off the parts of the wheel
rim that could be scratched in
the process of removing the
brake calipers.
Carefully pull the brake calipers
back and out until clear of the
brake discs.
When removing the left brake
caliper, take care not to dam-
age the ABS sensor cable.
When removing the right brake
caliper, take care not to alter

the routing of the sensor cable
of the brake-pad wear detector.
Raise front of motorcycle until
the front wheel can turn freely.
BMW Motorrad recommends
the BMW Motorrad front-wheel
stand for lifting the motorcycle.
Install the front-wheel stand
( 122)
Remove right-hand axle clamp-
ing screw5.
The left axle clamping
screw locates the threaded
bush in the front suspension.
If the threaded bush is not
correctly aligned the gap between the ABS sensor ring
and the ABS sensor will not be
correct and this can cause the
ABS to malfunction or allow the
ABS sensor to be damaged.
In order to ensure that the
threaded bush remains correctly
aligned, do not slacken or
remove the left axle camping
screw.
Remove quick-release axle 6,
while supporting the wheel.
Lower the front wheel to the
ground between the front forks.
Take care not to dam-
age the ABS sensor when
rolling out the front wheel.
Note the ABS sensor when
rolling out the front wheel.
Roll the front wheel forward to
remove.
Installing front wheel
ABS malfunctions on ac-
count of incorrect speed
signal.
Segmentation differs between in-
dividual types of sensor ring; it is
very important to ensure that the
correct sensor ring is installed.
Install only the sensor ring that
matches the motorcycle's con-
struction status.
Threaded fasteners not
tightened to the specified
torque can work loose or their
threads can suffer damage.
Always have the security of the
fasteners checked by a specialist
workshop, preferably an author-
ised BMW Motorrad dealer.
The front wheel must be
installed right way round to
rotate in the correct direction.
Note the direction-of-rotation ar-
rows on the tyre or the wheel
rim.
