Repair or replace defective wire harness.
|
| 3 |
DPF® differential pressure sensor check
1)Check DPF® differential pressure sensor.
Is check result OK?
|
Go to Step 4.
|
Replace DPF® differential pressure sensor.
|
| 4 |
DPF® differential pressure sensor hose and pipe check
1)Check DPF® differential pressure sensor hose and pipe for obstructions, damage, leakage and, breaks.
Is check result OK?
|
Go to Step 5.
|
Repair or replace defective part(s).
|
| 5 |
DTC check
1)Check DTCs.
Is DTC P1206, P2002, P226D or P24A4 detected?
|
Go to troubleshooting for DTC P1206, P2002, P226D or P24A4.
|
Go to Step 6.
|
| 6 |
DPF® replacement
1)Replace DPF®.
2)Clear DTC.
3)Set ignition “ON”.
4)Check DTCs.
Is DTC P2453, P2454 or P2455 still detected?
|
Replace ECM and recheck DTC.
