unstable vehicle conditions.
BMW Motorrad ASC is unable to
intervene effectively under these
conditions.
TPC
with Tire Pressure Control
(TPC)
OE
Function
A sensor is located in each tire,
which measures the air temper-
ature and the inflation pressure
inside the tire and sends these
values to the control unit.
The sensors are equipped with a
centrifugal governor, which does
not enable the transmission of
the measured readings until the
defined minimum speed is ex-
ceeded for the first time.
Minimum speed for
transmission of TPC
measured data:
min 6 mph (min 10 km/h)
Before initial reception of the tire
inflation pressure, -- is shown
in the display for each tire. The
sensors continue to transmit the
measured readings for some af-
ter the vehicle comes to a stop.
Duration of measured
data transmission after
motorcycle is stationary:
min 15 min
If an TPC control unit is fitted but
the wheels have no sensors, a
fault message is generated.
Tire inflation pressure
ranges
The TPC control unit distin-
guishes between three inflation
pressure ranges matched to the
motorcycle:
Inflation pressure within the
permissible tolerance.
Inflation pressure at the limits
of the permissible tolerance.
Inflation pressure outside the
permissible tolerance.
Temperature
compensation
The tire inflation pressure is tem-
perature dependent, i.e. it in-
creases or decreases together
with the tire air temperature. The
tire temperature is dependent on
the outside temperature, the rid-
ing style and the length of the
journey.
