Cummins ACM Aftertreatment Control Modules
Cummins ACM (Aftertreatment Control Module) units are critical electronic components responsible for managing and controlling the aftertreatment system in modern Cummins diesel engines. These modules monitor and regulate key emissions components such as the DPF, SCR, and DEF dosing system to ensure compliance with emissions standards and optimal engine performance. At Advanced Truck Parts, we supply Cummins ACM modules designed for reliable operation in heavy-duty and medium-duty applications.

Cummins ACM Modules in Aftertreatment Systems
The Aftertreatment Control Module (ACM) serves as the central controller for emissions systems, processing data from sensors and controlling components to maintain proper operation and emissions compliance.
Common Cummins ACM functions include:
- Controlling DEF dosing and SCR operation
- Managing DPF regeneration cycles
- Monitoring NOx and exhaust temperature sensors
- Communicating with the ECM for integrated engine control
Proper ACM operation is essential for emissions compliance, fuel efficiency, and overall engine reliability.
Common Cummins Applications
Cummins ACM modules are used in engines equipped with advanced aftertreatment systems across on-road and off-road platforms.
- Cummins ISX CM2250 and CM2350 engines
- Cummins X15 Efficiency and Performance Series
- Cummins ISB 6.7L engines
- Kenworth, Peterbilt, Freightliner, and International trucks
Module configuration depends on engine platform, emissions generation, and vehicle setup.
Common ACM Failure Symptoms
- Check engine or aftertreatment warning lights
- DEF dosing or SCR system faults
- Failed or incomplete DPF regeneration
- Engine derate conditions
- Communication faults with ECM or sensors
Failures may result from internal electronic faults, wiring issues, sensor failures, or software/calibration problems.
Installation & Programming Considerations
Replacing a Cummins ACM requires proper setup and programming.
- Verify correct module and compatibility
- Inspect wiring harness and connectors
- Perform required programming and calibration
- Check for related faults in the aftertreatment system
Correct installation ensures proper emissions control and system integration.
Verify Fitment Before You Buy
Cummins ACM modules vary by engine model, ESN, and emissions configuration. To ensure correct fitment, provide:
- Engine serial number (ESN)
- Engine model (ISX, X15, ISB 6.7, etc.)
- Vehicle VIN
- Existing module part number
- Truck year, make, and model
This helps confirm compatibility and prevents ordering incorrect electronic components.
