Description
Your CUMMINS CM 850-870 will be returned fully reconditioned, tested, and ready to be installed back to the exact vehicle it came off, saving you the time & expense of having a new ECM programmed to your machine.
The Cummins motors that use the ECM (Electronic Control Module) CM 850-870 include the ISX, QSX, ISL, ISC, and ISM engines. The CM 850 is mainly used in earlier-model engines, while the CM 870 is used in later-model engines. These ECMs are responsible for controlling various engine functions such as fuel injection, timing, and emissions.
