| Diagnostic Trouble Code | ||
|---|---|---|
| CDL Code | Code Description | Comments |
| E1014-2 | Low DPF #1 Intake Temperature : moderate severity (2) | The Aftertreatment Regeneration Device (ARD) has been running for at least 30 seconds. The temperature at the intake of the DPF is below 50° C (122° F). Active regeneration is immediately disabled. Engine power is derated. The code is logged. The code remains active until electrical power to the ECM is cycled. |
| Follow the troubleshooting procedure in order to identify the root cause of the fault. | ||

- Check for evidence of any gas leaks in the duct between the ARD combustion head and the DPF.
- Carefully inspect the duct between the outlet of the ARD and the intake to the DOC. Look for the following faults:
- Missing duct, cracked duct, or disconnected duct
- Loose clamps, broken clamps, or missing clamps
- Missing duct, cracked duct, or disconnected duct
- Make sure that the clamp between the DOC and the DPF is not missing, broken, or loose.
- Perform any necessary repairs.
