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
EC-1352, "Component Inspection"
.
Is the inspection result normal?
