Summary
This Warranty Field Campaign describes the recalibration steps for the engine control module to return units back to their original calibration prior to the issue of several Temporary Repair Practices (TRPs). These TRPs were issued to address certain vehicles with Diesel Exhaust Fluid (DEF) tank header sensor failures in which DEF tank header replacement parts were not available. Due to DEF tank header part shortages caused by the COVID pandemic, a temporary engine control module calibration was released that reduced inducement levels to allow for continued operation of the vehicle until DEF header parts became available for a final repair. As supply has recovered and DEF tank header parts have become more readily available, the TRPs have been discontinued. The temporary engine control module calibrations are being obsoleted and superseded back to the original calibration prior to the issue of the TRPs.

Description
This Emissions Campaign enables authorized repair locations to install a new DEF header and
recalibrate the ECM on certain engines where appropriate. The DEF header calibrations on eligible
units will be obsoleted and superseded back to the original calibration, at the latest revision level.
Action
In order to qualify for repair under this field action, an engine:
1. will be covered Regardless of coverage status, and
2. must show as OPEN on QuickServe® Online for this field action.
Note : The ESN list is attached for reference.
After verifying that the engine meets the above requirements, perform the following actions:
Note : The DEF header is an OEM component, and not available through normal
Cummins
parts channels. Parts are OEM specific. Please refer to TSB210187 for
details on obtaining the appropriate DEF header parts. Follow the steps outlined in the
parts ordering section.
1. Inspect the DEF header and the DEF gauge. If the wires are intact AND the DEF gauge is
functional, then go to step 3. Otherwise, proceed to step 2.
2. If the unit is NOT fitted with an updated DEF header, follow the steps outlined in the parts
installation section of TSB210187 to install the DEF header.
3. To obtain the correct ECM code and update to the latest revision level, follow the steps
outlined in the resolution section of TSB210187 to download the applicable ECM calibration.
The applicable ECM code can be found using the ECM code lookup tool or ECM code list. IF
the ECM already contains the new ECM code and the most recent calibration revision, DO NOT
recalibrate the engine; no further calibration action is needed.
4. After updating the calibration, let the engine run for 5 minutes. If fault codes 3868, 4677, OR
4572 are flagged, then a new DEF header is required to complete the repair. Refer to
TSB210187 to order a new DEF header and complete the repair.
Note : Certified repair locations outside of California, who elect to perform this
campaign on engines installed in vehicles which are registered in the state of
California, are authorized to do so if they have the two items noted below in their
inventory. Please note that the Label, Authorized Change and the Proof of
Correction Form must be ordered through standard parts processes. They
are not available on QuickServe® Online.
5. If applicable, a Label Authorized Change, Cummins
part number 5297400, must be filled out
and affixed to the engine. Clearly print or type DEF header UPDATE in the center box. Fill in the
Campaign Number, Distributor or Dealer Code, and Date information. Peel off the backing
material and install the label on the engine valve cover near the engine data plate. There is a
clear protective cover on this label; peel the backing off of this cover and push the clear cover
over the printed material. This will help protect the label during engine operation. Label cost
and appropriate SRT time can be claimed per Campaign guidelines.
6. If applicable, an Emissions Campaign - Proof of Correction form, Bulletin # 4310621, must be
filled out and provided to the Customer. Inform the Customer to retain this certificate as proof
that the Emissions Campaign has been performed. This form may be required as proof of an
Emissions Campaign by the State of California, for vehicles registered in that state, the next
time the vehicle registration is renewed. Form cost and appropriate SRT time can be claimed
per the Campaign guidelines.
7. File one claim for the listed parts and required labor associated with this repair. There are
restrictions to claimables based on the OEM application and DEF Header and calibration
status. Claim ONLY the SRTs required to complete the repair.
Material Disposition
Materials removed as a result of this field action must be scrapped. Follow the OEM specific
instructions where appropriate.
Reimbursements
Parts

claimable SRT time for the specific application. Where required for registration
purposes, SRT 17-901 can be claimed for the application of the Label Authorized
