RDC
with tyre pressure monitoring
(RDC)
OE
Function
A sensor integrated into each
tyre measures the air tempera-
ture 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 a defined min-
imum speed for the first time.
Minimum speed for
transmission of the RDC
measured values:
min 10 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 signals for some
time after the vehicle comes to a
stop.
Time for transmission of
measured values after
vehicle comes to a stop:
min 15 min
An error message is issued if
wheels without sensors are fit-
ted to a vehicle equipped with an
RDC control unit.
Tyre-pressure ranges
The RDC control unit differenti-
ates between three tyre-pressure
ranges, all of which are paramet-
erised for the motorcycle:
Tyre pressure within permitted
tolerance.
Tyre pressure close to limit of
permitted tolerance.
Tyre pressure outside permit-
ted tolerance.
Temperature
compensation
Tyre pressure is a temperature-
sensitive variable: pressure in-
creases as tyre-air temperature
rises and decreases as tyre-air
temperature drops. Tyre-air tem-
perature depends on ambient
temperature as well as on the
style of riding and the duration of
the ride.
The tyre-pressure read-
ings in the multifunction
display are temperature-com-
pensated and are always refer-
enced to the following tyre-air
temperature:
20 °C
The air lines available to the pub-
lic in petrol stations and motor-
way service areas have gauges
that do not compensate for tem-
perature; the reading shown by
a gauge of this nature is the
temperature-dependent tyre-
