SCARABEO 500
Checking under regular functioning by placing the
specific tool between the pump and the injector.
With >12V battery voltage, check that the fuel
pressure is 3 BAR and that the input current is ~2.8
A
With the >12V battery voltage, check the pump flow rate by disconnecting the pipe fitted with the pres-
sure gauge of the appropriate tool from the injector. Place a graded burette with a flow rate of
approximately 1 L. Make the pump turn with the active diagnosis on the palm top computer. Using a
pair of long flat needle-nose pliers, choke the fuel pipe making the pressure stabilise at approx. 2.9 ÷
3 BAR. Be careful not to further choke the pipe since the pressure remains equal to 3 BAR while the
capacity decreases. Check that, within 15 seconds, the pump has a flowrate of approx. 300 cm³.
