SUBJECT
CUMMINS ISX12 2013 ENGINE NOx SENSOR CALIBRATION UPDATE
CONDITIONS
SERVICE BULLETIN 440 WAS REVISED TO REFLECT SPECIFIC UNIT NUMBERS
IN PLACE OF A VIN RANGE LIST
Customer Complaint:
MCI is notifying customers that Cummins Inc. has released Campaign C1846 that addresses calibration issues
on ISX12 2013 engines in certain motor coach applications.
Cause:
NOx sensor tolerance.
Corrective Action:
MCI strongly encourages owners of the MY2014, MY2015 and MY2016 D series and J4500 model coaches
equipped with an ISX12 2013 engine listed in this bulletin to have an engine ECM calibration performed by an
authorized Cummins repair facility.
Customers must reference Cummins Campaign Number C1846 for the engine ECM calibration at
an authorized Cummins repair facility.
Please note that Cummins recommends, but does not require that the re-calibration under its
campaign C1846 be performed while the affected coach is undergoing another Cummins
warrantable repair event, to allow for reimbursement of charges not within the scope of C1846.
The engine NOx sensor recalibration is being performed only by Cummins Service Network and
its authorized dealers. Therefore labor required for this program will be provided by Cummins.
In order to update our records, MCI is asking customers to submit an MCI Field Change Program
Verification Form for each affected VIN for which Cummins has completed its campaign.
If you have any concerns or difficulties making arrangements with the Cummins Service
Network relating to this program, please contact our Customer Service Line at 1-800-241-2947.
