DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
DTC recheck
2)Set ignition “OFF”.
Is DTC P0601, P0606, P0607, P060A, P060D, P0611, P061A, P061B, P061C, P061D or P1623 still detected?
|
Go to Step 3.
|
|
| 3 |
ECM power supply circuit and ground circuit check
1)Check “B1”, “B2”, “B3”, “C1”, “C2” and “C3” circuits according to Step 2 of DTC P0562 / P0563:D16AA.
Is check result OK?
|
Repair or replace defective wire harness.
