Connect the tester to the diagnostic socket.
Disconnect the injector connector.

Turning the crankshaft of the engine with a starter for 2 seconds, visually check that there is no leakage of fuel through the connections.
Having turned the engine crankshaft with a starter, measure the fuel pressure 20 seconds after the end of crankshaft cranking. The required value is at least 1 MPa.
If the fuel pressure value is less than 1 MPa, then this means that there are leaks in the high pressure fuel system.
Turning the ignition key to the OFF position (OFF), connect the intermediate connector of the injectors.
Disconnect the tester.
