DDE EA0004469754 | CONTROL UNIT EXHAUST ACM 2.1

Description

The DDE EA0004469754 Control Unit (ACM 2.1 – Aftertreatment Control Module) is an OEM electronic module designed to control and monitor the exhaust aftertreatment system in heavy-duty diesel engines. It regulates DEF (Diesel Exhaust Fluid) dosing, monitors NOx sensors, and manages regeneration cycles for the DPF (Diesel Particulate Filter) to ensure optimal operation of the SCR (Selective Catalytic Reduction) system.

A fully functional ACM 2.1 is critical for meeting EPA and Euro emissions standards, preventing costly breakdowns, and maintaining engine performance. Replacing a faulty unit with a genuine DDE component ensures accurate communication between the aftertreatment system and the MCM (Motor Control Module).
