DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
Turbocharger actuator (+) drive circuit and (–) drive circuit check
1)Check “A1” and “A2” circuits according to Step 2 of Turbocharger Actuator Operation Check:D16AA.
Is check result OK?
|
Go to Step 3.
|
Repair or replace defective wire harness.
|
| 3 |
Turbocharger actuator check
1)Check turbocharger actuator.
Is check result OK?
|
Replace ECM and recheck turbocharger actuator operation.
|
Replace turbocharger with exhaust manifold.
