Introduction

The following procedure describes the process that must be followed when the engine, ECM or CEM is replaced.

Engine Replacement or Engine Control Module (ECM) Replacement without DPF Replacement

If the engine or ECM are replaced, then determine the most recent cleaning of the DPF.

1. If the diesel particulate filter was cleaned within the last 500 hours of operation, an ash cleaning procedure is not required. Reset the engine ash model, Refer to Troubleshooting, "Cat ET Service Features, DPF Ash Service" for additional information.

2. If the diesel particulate filter was not cleaned within the last 500 hours of operation, clean the DPF. Refer to Special Instruction, REHS5045, "Diesel Particulate Filter (DPF) Maintenance on Tier 4 Products Equipped with a Diesel Particulate Filter (DPF)" for additional information. Refer to Systems Operation and Testing and Adjusting, "Diesel Particulate Filter - Clean" for the correct procedure.

DPF Replacement without an Engine Replacement

1. If the DPF has failed, replace the DPF and reset the engine ash model. Refer to Special Instruction, REHS5045, "Diesel Particulate Filter (DPF) Maintenance on Tier 4 Products Equipped with a Diesel Particulate Filter (DPF)" for additional information.
