6.1. READ AND DIAGNOSE TPMS VALVES
Before wheel or tyre maintenance, use your TPMS tool to
check each vehicle sensor. In this way you can be sure
that they are all working correctly.
This procedure also lets you check the pressure of each
tyre, and preventively replace any damaged or defective
sensors or those with batteries coming to the end of their
life.
Note that simply reading the TPMS sensors with the tool does not affect the TPMS
settings of the vehicle.
Note: If the sensor does not respond, refer to the "Troubleshooting" section of this guide.
1 - Carrying out wheel or tyre maintenance.
2 - Take the first TPMS reading on the front left wheel. To do this, place the tool against
the side of the tyre, directly on the rubber and in immediate proximity to the valve. For
clearly visible TPMS sensors mounted outside of the tyre, simply move the tool towards
the sensor. Finally, the sensors circled directly inside the wheel rim are triggered by putting
the TPMS tool on the tyre rubber and staying close to the sensor.
3 - Press the green "Sensor activation" button on the TPMS tool to start the reading of the
TPMS sensor.
If the sensor reading is OK the device vibrates,
the green "Pass" LED light comes on, and there
is an audible signal if this is activated.
This procedure should be carried out on all wheels of the vehicle, in an anticlockwise
direction, and according to the diagram given in the figure below (for example).
