This notice applies to your engine(s)/vehicle(s) listed on the enclosed table.

 

WHAT IS THE PROBLEM?

Under certain conditions, the engine tailpipe exhaust may intermittently contain excessive ammonia.  Persons around the vehicle may smell ammonia.  Exposure to ammonia at elevated concentrations may cause personal injury.

 

WHAT ARE WE DOING ABOUT THE PROBLEM?

Cummins has released field Safety Campaign #C2460 L9 MY21 Transit Bus Calibration Safety Campaign to correct this condition by recalibrating the Engine Control Module.  This campaign is currently available at Cummins Distributors and authorized Warranty Dealers.

Federal law requires vehicle lessors receiving this recall notice to forward a copy of this notice to the lessee within ten (10) days.  Also, it is a violation of Federal law for a dealer to deliver a new vehicle or equipment covered by this recall notice under a sale or lease until the defect has been remedied.

If you previously paid to have this recall performed on your vehicle, you may be eligible for reimbursement.  Please contact Cummins Care at the number below for more information.

 

WHO SHOULD YOU CONTACT IF YOU HAVE FURTHER QUESTIONS OR CONCERNS?

If you have questions or concerns about this recall, please contact your local Cummins Distributor or authorized warranty dealer.  You may also contact Cummins Care at 1-800CUMMINS (1-800-286-6467), or visit our website at care.cummins.com.

DESCRIPTION:

This Safety Campaign is being issued to address the potential for excessive ammonia in the engine tailpipe exhaust. Exposure to ammonia at elevated concentrations may cause personal injury. This Safety Campaign authorizes certified repair locations to recalibrate the engine control module (ECM).

 

NOTE: This field action provides retroactive coverage for repairs made in anticipation of and prior to the release of this publication.

 

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:

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 calibration revision is installed, download the latest calibration available on QuickServe® Online. Use the calibration revision history date to identify the latest calibration revision available. Please refer to Procedure 019-032 in the appropriate Service Manual.

 

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.

3. If applicable, a Label Authorized Change, Cummins part number 5297400, must be filled out per the attachment. Clearly print or type ECM RECALIBRATION 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. 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.

 

5. File one claim for the listed parts and required labor associated with this repair. Again, SRT 17-902 should ONLY be claimed if the unit DID NOT require calibration.

 

MATERIAL DISPOSITION:

Materials removed as a result of this field action must be scrapped.

Winnipeg, MB R2C 3T4

 

Dear Cummins OEM Customer:

 

We are writing to inform you that Cummins Inc. has determined that a safety-related defect exists in certain EPA MY 2021 L9 engines that were manufactured between September 24, 2018 and June 22, 2021. Cummins has initiated a recall of the subject engines. Our records indicate that some of these engines have been shipped to you.

 

A copy of Cummins’ initial Part 573 Defect Notification report is enclosed. This notification was submitted to the National Highway Traffic Safety Administration (NHTSA) on June 29, 2021. As more fully described in the Defect Notification, the engine tailpipe exhaust may intermittently contain excessive ammonia, which may increase the risk of personal injury.

 

Enclosed is a list of Engine Serial Numbers for affected engines that our records indicate were shipped to your plants. For engines installed in vehicles that have left your control, we encourage you to make a safety defect determination in accordance with 49 USC 30118 et seq. and, as appropriate, to submit a Defect Notification to NHTSA in accordance with 49 CFR Part 573 Cummins will conduct the recall, including notifying owners pursuant to 49 CFR Part 577, performing the remedy, and submitting quarterly status reports to NHTSA. Cummins is requesting that you provide the associated vehicle model identification, VINs and owner contact information to facilitate owner notification. Please work with your Cummins account team leader to ensure that the requested information is provided to Cummins as soon as possible.

 

Cummins is finalizing the remedy (a new calibration) to address this condition. Availability of this calibration and Cummins’ plan for support to update engines/vehicles still in your inventory will be communicated separately. Please contact your Cummins OEM Customer Quality representative for more information. Please note that Federal law prohibits delivery of these engines, or vehicles equipped with these engines, under a sale or lease until this condition has been remedied.

 

Cummins will conduct a safety campaign to remedy the issue with a new engine calibration.

 

Cummins apologizes for this inconvenience, but we are initiating this action in the interest of our customers’ safety and satisfaction with our products. Thank you for your assistance.

 

Please confirm receipt of this communication.

 

Sincerely,
