Aftertreatment Diesel Particulate Filter Differential Pressure - Data Valid but Above Normal Operational Range - Moderately Severe Level. The soot load of the aftertreatment diesel particulate filter has exceeded the recommended limits.

CODEREASONEFFECT
Fault Code: 2637
PID:
SPN: 5018
FMI: 11/11
LAMP: None
SRT:

Catalyst Face Plugged - Root Cause Not Known. The front face of the aftertreatment diesel oxidation catalyst has been detected to be plugged with soot.

 

Active aftertreatment diesel particulate filter regeneration will be disabled.

Your most severe faults are above, all of them pertain to the aftertreatment filter being plugged. you must run a stationary regen as per OEM instructions, there should be a switch in the cab to perform this. If your dpf cannot be cleaned via the regen it must be checked by a shop and cleaned on the cleaner machine, also ecm software updates are available for DPF issues

Expert:  DR.Cummins replied 2 years ago.

The soot load of the aftertreatment diesel particulate filter has exceeded the recommended limits, and will need to be removed and inspected. Than cleaned on the DPF cleaning machine, than again checked for serviceability. I recommend you find a Cummins dealer ASAP, A failed DPF will create more issues such as egr and vgt turbo problems. low power, excessive carbon build up. ect.
