improved SCR Catalyst, if the engine meets the criteria listed below. For MY2013 thru MY2014 engines
that qualify for a new SCR Catalyst, a new wiring harness connector plug and a calibration update will be
required.
Note : This field action provides for retroactive coverage of repairs, including customer billable
repairs, completed by Cummins authorized repair locations prior to the release date of this field
action. Previous repairs may be eligible for reimbursement of ONLY the work defined in this
publication. Service providers should have invoice documentation of original repair ready for
support of the retroactive claim. All Service Providers attempting to file claims for retroactive
repairs should refrence Warranty Memo M1825 for instructions.
Note : If original repair was not completed by a Cummins authorized repair location, the labor
amount is not reimbursable. ONLY parts will be reimbursed.
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 an OPEN status for this field action on QuickServe® Online, and

3. must experience a complaint or symptom in which troubleshooting results in the replacement of the
SCR catalyst.
4. For ISB and ISL CM2350 (Model Year 2013 thru 2014 Product) the SCR Part Number must be
compared with Attachment B. Any SCR Part Number found in the Affected Part Number Column
should be replaced. If the SCR Part Number is not found in the Affected Part Number Column, the
engine is not eligible for this action.
After verifying that the engine meets the above requirements, perform the following actions:
1. If all qualifying parameters detailed above are met, please refer to Attachment B for a listing of affected
SCRs and related replacement SCR part numbers that must be used in completing this TRP and
which takes precedence over any other prior published service/part guidelines, for the duration of this
TRP.
Note : For eligible ISB CM2350 and ISL CM2350 (Model Year 2013 thru 2014 Product)
the SCR catalyst must be replaced. Refer to procedure SCR Catalyst Remove and Install
in section 011-036 of Service Manuals 2883567 (ISB6.7 CM2350 B101), 4332641 (ISB6.7
CM2350 B103),5411131 (ISB6.7 CM2350 142), 4310787 (ISL9 CM2350 L101), or
4367223 (ISL9 CM2350 L111). 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
instructions on installing and securing the wiring harness connector plug.
2. Download the latest calibration available on QuickServe® Online. Recalibrate the ECM as described in
Procedure 019-032 of Service Manuals 2883567 (ISB6.7 CM2350 B101), 4332641 (ISB6.7 CM2350
B103), 5411131 (ISB6.7 CM2350 142), 4310787 (ISL9 CM2350 L101), or 4367223 (ISL9 CM2350
L111).
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 "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. Please refer to Attachment E for a representative sample of the Emissions
Campaign - Proof of Correction Bulletin.
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, troubleshooting or repairs not listed in the parts and labor sections below cannot be filed
to this field action.
