NOTE:
• Conditions for applying the diagnostic procedure to the stored DTCs:

The DTC is declared present after the engine has been started.

• If the DTC is present:
- Malfunction indicator (Red) lights up.

Diagnosis Procedure

INFOID:0000000000954969

1.

CHECK FUEL INJECTOR POWER SUPPLY CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Disconnect fuel injector harness connector.

4.

Check the continuity between fuel injector harness connector and ECM harness connector.

5.

Also check harness for short to ground and short to power. 

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

2.

CHECK FUEL INJECTOR OUTPUT CIRCUIT FOR OPEN AND SHORT

1.

Check the continuity between fuel injector harness connector and ECM harness connector.

2.

Also check harness for short to ground and short to power. 

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

3.

CHECK FUEL INJECTOR 

Refer to 

EC-1352, "Component Inspection"

.

Is the inspection result normal?

DTC No.
