Bad One Box on a Freightliner Cascadia Part 1

Check engine light, Malfunction indicating light and Stop engine light were all on.
Always try to do a parked regen in order to see how the truck responds to temperatures and pressures inside the One Box. In some cases a parked regen will help clear the fault codes.
This One Box did have to come out in order to get a visual of the inside and the DOC filters.

These are the fault codes that were present:

SPN 3251 FMI 0 DPF Pressure out of range Very High
SPN 3251 FMI 2 DOC Inlet pressure sensor not plausible
SPN 3251 FMI 16 DPF pressure out of range high
SPN 3556 FMI 18 DOC inlet temp low
SPN 3246 FMI 15 DOC outlet temp high
