8- The fuel pump was activated 10 times and the tester returned the «test successfully completed»
outcome. The pump and the relative circuit are currently efficient. For greater certainty, proceed with
the auto-diagnostic check in order to highlight any errors in stored status.
9- The pump remained inactive and the tester returned the «test failed» outcome. Repeat the diagnostic
and, if necessary, replace the ECU.

12- No error present. The pump's electric command circuit is efficient. For a more complete check,
proceed with the check on the fuel supply circuit.
13- Fuel pump error in occurred or stored status. Proceed with the check on the pump and the control
circuit, paying particular attention to false contacts or uncertain insulation.
14- Fuel pump error in actual state. Proceed with the check on the fuel pump supply circuit.
15- Connect the interface wiring. Omit the connection with the ECU. Disconnect the fuel pump supply
connector.
