This Mopar engine control module is designed specifically for 2013–2015 Ram trucks with the 6.7L Cummins diesel, covering Ram 2500 and 3500 applications in popular trims like Tradesman, SLT, Big Horn, Lone Star, Laramie, and related packages. It is an OEM replacement ECM that maintains factory-style integration with the truck’s wiring, sensors, and emissions systems.
The ECM functions as the brain of the 6.7L Cummins engine management system, controlling fuel injection timing and quantity, turbocharger behavior, exhaust aftertreatment, and key safety and diagnostics routines. When the original module fails or becomes corrupted, owners can experience no-start conditions, derates, random codes, or inconsistent drivability, making a proper OE replacement module critical for getting the truck back to reliable operation.
This unit is the updated 68170201AB part number, which replaces the earlier 68170201AA revision and is intended as the current service part for affected 2013–2015 vehicles. As a genuine Mopar component, it is built to OE specifications so that it works seamlessly with factory harnesses, sensors, and Cummins-specific engine strategies, making it a strong choice for daily driven work trucks, heavy towing rigs, and fleet vehicles that need predictable, long-term reliability.
In most cases, installation of this ECM will require proper programming or flashing with the correct vehicle identification and calibration files using OEM-level tools or a qualified service provider. The module is intended to support stock or OEM-style calibrations; any performance tuning or custom programming should be done only by experienced professionals who understand the implications for emissions systems and warranty considerations.
For owners searching for terms like “2013–2015 Ram 6.7L Cummins Mopar ECM,” “68170201AB engine control module,” or “replacement ECM for Ram 2500/3500 6.7 Cummins,” this part provides an OE-focused solution. Using a genuine Mopar ECM helps ensure correct communication with the rest of the truck’s modules, reduces the risk of compatibility issues, and supports factory-level drivability and diagnostics on late-model Cummins-powered Rams.
