DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.

Turn ignition switch OFF and wait at least 12 minutes.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 12 minutes.

TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start the engine and wait at least 5 seconds.
If engine does not start, crank engine for at least 4 seconds.

2.

>> Proceed to 

ECH-160, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000010499992

1.

CHECK FUEL LEAKAGE

1.

Start the engine.

2.

Visually check that the fuel pump, fuel rail, fuel injector and fuel piping have no fuel leakage.

Is the inspection result normal?

YES

>> Check that the fuel system has no breakage, bend, and crush. Refer to 

FL-5, "Inspection"

.

NO

>> Repair or Replace the error-detected parts.

DTC No.
