B4: CHECK THE POWER SUPPLY CIRCUIT TO THE FUEL PUMP
Reconnect the fuel pump module connector, CA105.
Disconnect the fuel pump connector:
Vehicles with 2.5/3.0 L engine, ROW;
FT02.
Vehicles with 2.5/3.0 L engine, USA;
FT06.
Turn the ignition switch to the ON position.
Measure the voltage between:
Vehicles with 2.5/3.0 L engine, ROW;
FT02, pin 02 (R) and GROUND.
Vehicles with 2.5/3.0 L engine, USA;
FT06, pin 06 (R) and GROUND.
Is the voltage less than 10 volts?
Yes
INSTALL a new fuel pump module.
REFER to:
Fuel Pump Module - 2.0L NA V6 - AJV6
(310-01 Fuel Tank and Lines, Removal and Installation) /
Fuel Pump Module - 2.5L NA V6 - AJV6/3.0L NA V6 - AJ27
(310-01 Fuel Tank and Lines, Removal and Installation).
CLEAR the DTC, test the system for normal operation.
No
GO to B5
.
B5: CHECK THE SIGNAL GROUND CIRCUIT FOR CONTINUITY
Disconnect the fuel pump module connector, CA105.
Measure the resistance between CA105, pin 03 (Y) and:
Vehicles with 2.5/3.0 L engine, ROW;
FT02, pin 04 (Y).
Vehicles with 2.5/3.0 L engine, USA;
FT06, pin 01 (Y).
Is the resistance greater than 5 ohms?
Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the
system for normal operation.
No
INSTALL a new fuel pump module.
REFER to:
Fuel Pump Module - 2.0L NA V6 - AJV6
(310-01 Fuel Tank and Lines, Removal and Installation) /
Fuel Pump Module - 2.5L NA V6 - AJV6/3.0L NA V6 - AJ27
(310-01 Fuel Tank and Lines, Removal and Installation).
CLEAR the DTC, test the system for normal operation.
PINPOINT TEST C : FUEL TRANSFER TEST
WARNING: Use extreme care when carrying out the fuel transfer test not to endanger other road users or infringe any road traffic
regulations. Ideally, this should be carried out away from public roads.
• NOTE: Make sure the fuel tank is between one quarter and half full as indicated by the fuel gauge before beginning this test.
• NOTE: If the 'F2****' value in step 6 of this test is '255', suspect an open or short circuit through the level sensor.
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
C1: CHECK THE 'F2****' VALUES
Turn the ignition switch to the OFF position.
Depress the trip button on the indicator stalk and turn the ignition switch to the ON position.
Continue to hold the trip button in until 'TEST' appears on the instrument cluster display.
Release the trip button.
Press the trip button repeatedly until 'F2****' is displayed (this is the sender value of the transfer fuel pump
module).
Start the engine and drive the vehicle in a tight right-hand circle to transfer fuel from the fuel pump module side of
the fuel tank to the transfer pump module side.
Monitor the 'F2****' value (with assistance, if necessary), and once the value is greater than 60, bring the vehicle
to rest.
Monitor the 'F2****' value over approximately 3 minutes.
Does the 'F2****' value decrease steadily?
Yes
If the 'F2****' value decreases steadily, this indicates that fuel is transferring.
No
If the 'F2****' value does not decrease, or increases, return to the symptom chart and follow the actions listed for
'engine stops with fuel indicated on the gauge'.
PINPOINT TEST D : FUEL PUMP NOISE (VEHICLES WITH 2.5/3.0L ENGINES ONLY)
• NOTE: A certain amount of 'swishing' from the fuel tank is normal as fuel is transferred around the fuel modules.
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
D1: VERIFY THAT THE FUEL PUMP IS THE SOURCE OF THE NOISE
Apply the parking brake.
