• Connect the manometer, see Fuel pressure gauge
• Run the engine to operating temperature. Allow the engine to idle
• air conditioning (A/C) off
• Read off the relative fuel pressure.

  The relative fuel pressure is calculated from the fuel pressure sensor and the atmospheric pressure sensor signal (= absolute pressure minus atmospheric pressure).

  Check that the value on the manometer and the value displayed in VIDA are the same. If the values are different, this indicates incorrect function.
