Sorry, I was able to get 3729 before detroit site crashed. you need to replace dpf for this code and re set the ash count.

I will try back a little later for the other codes



141.1  SPN 3720/FMI 15

This fault indicates that the Diesel Particulate Filter (DPF) has reached the end of its service life and must be replaced. Replace DPF and perform Ash Accumulator reset using DDDL. ‪

The DPF lamp will illuminate and SPN 3720/FMI 15 will log when the truck reaches the appropriate mileage interval. This fault indicated that the DPF needs to be replaced and the DPF Ash Accumulator Routine in DDDL/DDRS must be completed. This routine can be found in the Actions drop-down menu and must be completed after the DPF has been replaced.‪

Cleaning accumulated ash from the DPF is a necessary part of vehicle maintenance and is a customer charge. The recommended service is to remove the DPF and replace with a reliabilt® Clean DPF. The reliabilt® Clean DPF has a parts warranty and the same cleaning interval as the original DPF.‪

NOTE: Using alternate cleaning methods may result in the cleaned DPF failing to reach the next Ash clean interval. The customer may experience damage to the Diesel Oxidation Catalyst (DOC) or DPF assemblies as a result of alternate cleaning methods.

Refer to section "Resetting the EPA07 Diesel Particulate Filter Ash Accumulators" .
