PROBLEM
In cold weather operation, the existing Diesel Particulate Filter (DPF) pressure lines may become restricted due to the freezing of the condensation in the lines. This may result in diagnostic and event codes that can disable the DPF regeneration system. Additionally, some engine software strategies related to DPF regeneration performance were not optimized for cold weather operation
