SCOPE

with the 6.4L V8 Heavy Duty Hemi MDS Engine (Sales

identified as not involved in this recall and therefore

in dealer new vehicle inventory. Dealers should
complete this campaign service on these vehicles
before retail delivery. Dealers should also perform this
repair on vehicles in used vehicle inventory and those
vehicles in for service. Involved vehicles can be
determined by using the VIP inquiry process.

REPAIR TO BE PERFORMED
Scan the PCM and confirm that the TLC learning is
completed, and if not, drive the vehicle to complete the
TLC learning.

inconvenience while the recall repair is being

performed.

FCA US LLC has determined that certain [2024 RAM (DJ) 2500 Pickup, (D2) 3500 Pickup, (DD)
3500 Cab Chassis, and (DP) 4500/5500 Cab Chassis] vehicles equipped with the 6.4L V8 Heavy
Duty Hemi MDS Engine require emissions system improvements.
WHY DOES MY VEHICLE NEED REPAIRS?
The Target Linear Compensation (TLC) learning in the Engine Control Module (ECM) on your
vehicle [1] may not have been completed. The On-Board Diagnostic (OBD) system requires the
completion of TLC learning to enable ECM misfire monitoring. Vehicles in this condition may
not have proper OBD monitoring active, which may not detect increases in emissions.
HOW DO I RESOLVE THIS IMPORTANT EMISSIONS ISSUE?
FCA US LLC will repair your vehicle free of charge (parts and labor). To do this, your dealer
will scan the ECM and confirm that the TLC learning is completed, and if not, drive the vehicle
to complete the TLC learning. The estimated repair time is 15 to 45 minutes. In addition, your
dealer will require your vehicle for proper check-in, preparation, and check-out during your
visit, which require more time. Your time is important to us, so we recommend that you schedule
a service appointment to minimize your inconvenience. Ask your dealer for alternate
transportation options while your vehicle is in service. Please bring this letter with you to your
dealership.
TO SCHEDULE YOUR FREE REPAIR,
CALL YOUR CHRYSLER, DODGE, JEEP OR RAM DEALER TODAY

registration renewal. Your dealer will provide you with a Vehicle Emission Recall Proof of
