DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
Fuel injector drive circuit (high side) and (low side) check
1)Check of “A1”, “A2”, “B1”, “B2”, “C1”, “C2”, “D1” and “D2” circuits according to Step 1 of Fuel Injector Circuit Check:D16AA.
Is check result OK?
|
Go to Step 3.
|
Repair or replace defective wire harness.
|
| 3 |
Fuel injector check
1)Check fuel injector.
Is check result OK?
|
Replace ECM and recheck DTC.
|
Replace fuel injector.
