The service menu consists of the following points and will only show functions that
are applicable for the preselected make model year combination.
All captured data will be stored automatically.
1/6 CHECK SENSOR
Use this function to test the fitted sensors before continuing with further steps.
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 sensor’s, the tool should be held 180°away from the stem.)
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.
The tool tries to read all possible sensor types that could be fitted to
the selected Make. The search will identify that the sensor is working,
although it may not be the correct sensor for a particular Make, Model
and Year combination.
