DTC CONFIRMATION PROCEDURE

1.CHECK DTC PRIORITY

If DTC P0461 is displayed with DTC UXXXX or P0607, first perform the trouble diagnosis for DTC UXXXX or P0607.

Is applicable DTC detected? YES >> Perform diagnosis of applicable. Refer to EC-93, "DTC Index".

NO >> GO TO 2.

2.PRECONDITIONING

WARNING: When performing following procedure, be sure to observe the handling of the fuel. Refer to FL-2, "General Precaution".

TESTING CONDITION: Before starting component function check, preparation of draining fuel and refilling fuel is required.

Do you have CONSULT? YES >> GO TO 3.

NO >> GO TO 4.

3.PERFORM COMPONENT FUNCTION CHECK

With CONSULT

NOTE: Start from step 10, if it is possible to confirm that the fuel cannot be drained by 30 (7-7/8 US gal, 6-5/ 8 Imp gal) in advance.

1.  Prepare a fuel container and a spare hose.
2.  Release fuel pressure from fuel line, refer to EC-144, "Work Procedure".
3.  Remove the fuel feed hose on the fuel level sensor unit.
4.  Connect a spare fuel hose where the fuel feed hose was removed.
5.  Turn ignition switch OFF and wait at least 10 seconds then turn ON.
6.  Select “FUEL LEVEL SE” in “DATA MONITOR” mode of “ENGINE” using CONSULT.
7.  Check “FUEL LEVEL SE” output voltage and note it.
8.  Select “FUEL PUMP RELAY” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.
9.  Touch “ON” and drain fuel approximately 30 (7-7/8 US gal, 6-5/8 Imp gal) and stop it.
10.  Check “FUEL LEVEL SE” output voltage and note it.
11. Fill fuel into the fuel tank for 30 (7-7/8 US gal, 6-5/8 Imp gal).
12.  Check “FUEL LEVEL SE” output voltage and note it.
13.  Confirm whether the voltage changes more than 0.03 V during step 7 to 10 and 10 to 12.

Is the inspection result normal? YES >> INSPECTION END

NO >> Proceed to EC-347, "Diagnosis Procedure".

4.PERFORM COMPONENT FUNCTION CHECK

Without CONSULT

NOTE: Start from step 8, if it is possible to confirm that the fuel cannot be drained by 30 (7-7/8 US gal, 6-5/8 Imp gal) in advance.

1.  Prepare a fuel container and a spare hose.
2.  Release fuel pressure from fuel line. Refer to EC-144, "Work Procedure".
3.  Remove the fuel feed hose on the fuel level sensor unit.
4.  Connect a spare fuel hose where the fuel feed hose was removed.
5.  Turn ignition switch ON.
6.  Drain fuel by 30 (7-7/8 US gal, 6-5/8 Imp gal) from the fuel tank using proper equipment.
7.  Confirm that the fuel gauge indication varies.
8.  Fill fuel into the fuel tank for 30 (7-7/8 US gal, 6-5/8 Imp gal).
9.  Confirm that the fuel gauge indication varies.

Is the inspection result normal? YES >> INSPECTION END

NO >> Proceed to EC-347, "Diagnosis Procedure".
