The owner pulls the DPF filter off the machine, does a wire test on both the DPF and DOC to check for clogging and ash buildup, sends both to a local diesel shop for baking, then reinstalls and checks the restriction reading on startup. Useful for L5460 owners chasing the same regen code.
Appears to be an owner or operator documenting their own repair process, not a dealership or professional technician presentation.
On the DOC the wire goes all the way through with no issue, but on the DPF some of it only goes in partway, showing clogging and ash buildup.
Remove the DPF filter, wire test it and the DOC for clogging, take both to a diesel shop to be baked, then reinstall with new gaskets.
After reinstalling the baked DPF and DOC and starting the machine, the display showed the restriction reading as clean.
