with tyre pressure monitoring
OE
(RDC)
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-
z
force tripswitch that does not
enable transmission of the meas-
ured values until the vehicle has
accelerated to about 30 km/h.
The display shows
tyre until the tyre-pressure signal
is received for the first time. The
sensors continue to transmit the
measured-value signals for ap-
proximately 15 minutes after the
vehicle 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
vehicle. An error message is is-
sued if wheels without sensors
are fitted to a vehicle equipped
with an RDC control unit.
Temperature
compensation
Tyre pressure is a temperature-
sensitive variable: pressure in-
creases as tyre temperature rises
and decreases as tyre temper-
ature drops. Tyre temperature
depends on ambient tempera-
ture, on the style of riding and
the duration of the ride.
--
for each
The tyre-pressure readings
shown by the multifunction
display are temperature-
compensated; the reference tyre
http://www.motorcycle.in.th
temperature for these readings
is always 20 °C. The air lines
available to the public in petrol
stations and motorway service
areas have gauges that do not
compensate for temperature; the
reading shown by a gauge of
this nature is the temperature-
dependent tyre pressure. In
most instances, therefore, these
gauge readings will not tally with
the pressures shown by the
multifunction display.
Pressure adaptation
Compare the RDC readings
on the multifunction display
with the value in the table on
the inside cover of the Rider's
Manual. Then use the air line to
compensate for the difference
between the RDC reading and
the value in the table.
