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. The following conditions can cause this code:
The exhaust piping between the outlet of the ARD and the intake of the DPF is disconnected and/or the DPF Inlet Temperature sensor has failed.

"ARD Ignition Test"
Result: The "ARD Ignition Test" was successful.
Return the engine to service.
Result: The "ARD Ignition Test" was not successful.
Repair: Replace the DPF Inlet Temperature sensor. Repeat the "ARD Ignition Test".
If the "ARD Ignition Test" was successful, return the engine to service.
If the "ARD Ignition Test" was not successful, troubleshoot the generated codes.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
