Description
This TRP is being issued to repair degraded fuel injectors with guidance from TSB230162 on certain X15 CM2450 X134B and X142B certified engines. Where authorized,
the full set of injectors will be replaced addressing a potential concern for fuel injector degradation, avoiding excessive regeneration or excessive soot accumulation in
DPF that leads to an engine light for associated fault codes listed below. This field action authorizes certified repair locations to remove and replace the fuel injectors
with renozzled and improved fuel injectors as received from a certified ReNozzle center. Completion of TSB230162 is required by all Distributor and Dealer Channels for
repairs claimed to this TRP.

Note : For Guidance on Timing and TRP Flow, please review Attachment B, FAQ Section, page 4.

1. must be within coverage limits for a valid warranty or extended coverage certificate covering fuel injector and,
2. must record one or more of any of the following symptoms or fault codes; FC1921, FC1922, FC1981, FC2639, FC3375, FC3376, Regeneration Excessive, and
3. must complete TSB230162 and receive Cummins Care Instruction to continue with TRP7020 and,

1. Overview

Overview

TRP T7020 provides authorization for certified repair locations to remove, ship, and reinstall fuel injectors
while completing repairs for certain engines according to TSB 230162.
The following pages detail the cleaning procedure and packaging instructions along with details to obtain a
Shipping Label to ship injectors to the nearest Rebuild Center.

2. TRP Timing and Flow FAQ

TRP FAQ

X15 Injector Field Action Usage and Interaction
 Cummins has released 2 Field Actions to support the X15 Fuel Injector Nozzle Replacement process. This program will ensure your
engine has the most-up-to-date injector hardware to prevent frequent regenerations and certain aftertreatment fault codes. Both Field
Actions will show as OPEN on QSOL for an eligible engine, but authorized Service Providers diagnosing and repairing the engine should
ignore TRP7019.
 TRP7020 was released to allow Cummins authorized Service Providers to diagnose an issue with fuel injectors based on TSB230162,
send the fuel injectors to a rebuild location for repair, and reinstall the upgraded injectors. The engine must be within coverage for a fuel
injector failure for TRP7020 to apply. Please follow all instructions in this TRP exactly to ensure the work performed is covered by the
program.
 TRP7019 applies to authorized Injector Repair Facilities ONLY and allows them to claim parts and labor for the work they are doing to
support TRP7020. TRP7019 only applies to certain locations and no other Service Providers are allowed to do this work. Ignore this
Action if you are not an authorized Injector Repair Facility.
Customer Communication
 The X15 Fuel Injector Nozzle Replacement process ensures that your engine has the most up-to-date injector hardware. This updated
hardware will prevent future downtime related to Aftertreatment failures and/or frequent regeneration.
 Cummins has worked closely with the Injector Repair Facilities to ensure they are adequately equipped and have the capacity to keep
up with demand. The cycle time to update the nozzle hardware for the injector is expected to take 2 days for overnight shipping and
goal of a 1-day turnaround at the Injector Repair Facility. Shipping times can vary pending geographical location.
 While there are some exceptions, this process should align with the same amount of cycle time that an injector replacement repair would
take.
