Connect the Examiner diagnostic equipment pressure transducer between the diesel filter (1) and the pressure pump (5) supply pipe (4).
Turn the ignition key to the ON position.
Within 10 seconds, check that the pressure reading on the gauge is between 2 and 3 bar.
The tank electric pump (9) will go off after around 10 seconds.
Make sure that the taps and the adjustment screws at the side of the pressure gauge are open (except the ones on ducts not connected to the system).
