    1. Turn the ignition off.
    2. Disconnect the FPCM harness connector.
    3. Disconnect the Fuel Pump Module harness connector.
    4. Measure the resistance of the (N11) Fuel Pump PWM Control circuit between the FPCM harness connector and the Fuel Pump assembly harness connector.

      Is the resistance below 3.0 Ohms?

      Yes 

      • Go To  3

      No 

      • Repair the (N11) Fuel Pump PWM Control circuit for an open or high resistance.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  3. CHECK THE (N12) FUEL PUMP PWM RETURN CIRCUIT FOR AN OPEN/HIGH RESISTANCE 
    1. Measure the resistance of the (N12) Fuel Pump PWM Return circuit between the FPCM harness connector and the Fuel Pump assembly harness connector.

      Is the resistance below 3.0 Ohms?

      Yes 

      • Replace the Fuel Pump assembly in accordance with the Service Information.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No
