Volvo Trucks – Tyre pressure monitoring explained


The Tyre Pressure Monitoring System helps the driver to keep full track
of tyre pressures. That is done via sensors that
are attached to the wheels. 30 seconds after starting the engine,
the pressure levels show up in the display. They can be consulted in the TPM menu. In that TPM menu, you can
scroll between the TPM Overview, the TPM Axle view,
and the TPM Battery Status, showing the remaining battery level
of the wheel sensors. In case of loss of pressure in a tyre,
a message will appear in the display. In this example, there is a fast leakage
in the left front tyre of the tractor. The pressure in the tyre has dropped
to 2.9bar and the tyre is replaced. Never forget to remove
the pressure sensors from the flat tyre and remount them on the new tyre. It takes 6 minutes before the pressure
of the new tyre appears in the display. The TPM system does not give
info on wear of tyres. Drivers should therefore always
check the tyres during the daily check. That reduces the risk for unplanned stops. As the left front tyre is new, the right
front tyre should now be replaced as well. There is not enough tread left on the
rear axle tyres either, so they are replaced too. Once again, don’t forget to remove the
sensors and remount them on the new tyres. Wait with connecting the sensor
to the valve of the tyre. That should be done in the right order,
following instructions in the display. The sensor on the left front tyre was
already connected and can stay like that. To start connecting the sensors of
the new tyres in the right order, the driver enters the
“Settings” menu, goes to “TPM”,
and then choses “Sensor Position”. The front left tyre is blinking in the
display, telling the driver to
connect that sensor first. As the sensor on the front left
tyre already has been connected, the driver can simply confirm
using the buttons on the steering wheel. The driver display now indicates
which sensor to connect next. When the sensor has successfully
been connected to the valve, the direction indicators will
blink 8 times to confirm that. Once all sensors are connected,
the TPM system is ready for usage again.
