1/6 CHECK SENSORS
Use this function to test the fitted sensors before continuing with further steps.
To check the status of the TPMS sensors on the vehicle, select Check Sensors from the Service
Screen. A screen similar to the following should be displayed:
Use the arrow keys to select the sensor which needs to be read.
LF activated sensors
To test a sensor the tool should be placed alongside the valve stem and the ‘Test’ key
pressed.
Tool Positioning
Do NOT touch the metal rim. The tool needs to point through the rubber at the sensor.
(Note: with Ford Banded sensors the tool should be held 180°/opposite from the stem’s
position)
Non-LF activated sensors (some Beru sensors up to 2009)
If the tool requires rapid tyre deflation (of the order of 10psi or 0.5bar), then deflate the tyre
and place the tool alongside the stem while pressing the test key.
During testing, the screen confirms the sensor type being tested and displays a progress bar.
Different makes of Sensors respond at different speeds/ time intervals.
