1. Use the ECM Calibration Revision History available on QuickServe® Online to
confirm the revision date of the calibration currently installed in the engine. If ECM
already contains the most recent calibration revision, DO NOT recalibrate the
engine, no further action is needed. File a claim for Admin and 17-902 Campaign
Check to close the eligibility of the engine.
2. If a previous revision is installed, download the latest calibration available on
QuickServe® Online. Recalibrate the ECM with calibration revisions released in July
2019 or later. Use the calibration revision history date to identify the latest calibration
revision available. Please refer to Procedure 019-032 in the appropriate Service
Manual.
3. Complete "Label Authorized Change," Cummins
Part Number 5297400. Clearly print
or type "ECM Calibration 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.
4. 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. The form
cost and appropriate SRT time can be claimed per the Campaign guidelines.
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. 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 QSOL.
