1. If all qualifying parameters detailed above are met, please refer to Warranty Memo #1925 to
verify eligibility and to determine the replacement SCR to use for the repair. If the unit is fitted
with an eligible SCR, only the identified replacement SCR must be used in completing this field
action. The verification and selection tool takes precedence over any other prior published
service/part guidelines, for the duration of this field action.

Note : For eligible ISL CM2350 L101 the SCR catalyst must be replaced. Refer to
procedure SCR Catalyst Remove and Install in section 011-036 of Service Manual
4310787 (ISL9 CM2350 L101). New SCRs delete the NH3 Sensor and move from a
three (3) sensor to a NEW two (2) sensor configuration. This action provides
coverage for a wiring harness connector plug to cap and secure the NH3 sensor
connector that will no longer be used. The installation of a wiring harness connector
plug in the NH3 sensor connector will require an ECM calibration update. Please
refer to Attachment C for a table of ECM base codes and CPLs for your
consideration. Please refer to Attachment D for detailed instructions on the
installation of the wiring harness plug.
2. Download the latest calibration available on QuickServe® Online. Recalibrate the ECM as
described in Procedure 019-032 of Service Manuals 4310787 (ISL9 CM2350 L101).
3. As required, complete "Label, Authorized Change," Cummins Part Number 5297400. Clearly
print or type "SCR Catalyst 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.
4. As required, an "Emission 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 Emission Campaign has been performed. This form may be required as proof of an Emission
Campaign by the State of California, for vehicles registered in that state, the next time the
vehicle registration is renewed. Please refer to Attachment E as an example.

Note : Certified repair locations outside of California, who elect to perform this
campaign on engines installed in vehicles that are registered in the state of
California, are authorized to do so if they have the two items noted above in their
inventory.
5. File one claim for only the applicable parts and labor listed in this document. Any labor or parts
for diagnostics or repairs not listed in the parts and labor sections above cannot be filed to this
field action. Provide documentation of the ECM calibration revision codes from before and after
the recalibration in the claim narrative.

Material Disposition
Where applicable, items removed should be returned to ReCon for core credit. Unless otherwise
indicated, items with no core liability can be scrapped.
