2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000011278004
1.
CHECK DTC WITH COMBINATION METER
MWI-21, "CONSULT Function (METER/M&A)"
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Proceed to
MWI-63, "Component Function Check"
2.
CHECK FUEL TANK TEMPERATURE (FTT) SENSOR POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect fuel level sensor unit and fuel pump harness connector.
