What an Aftertreatment Control Module (ACM) Does
The ACM controls multiple emissions systems used in modern diesel engines. It manages diesel particulate filter (DPF) regeneration cycles, diesel exhaust fluid (DEF) dosing, selective catalytic reduction (SCR) functions, and monitors numerous emissions sensors throughout the exhaust system.
How the ACM Works With Other Modules
The ACM communicates with the engine control module (ECM) and other vehicle control units to maintain emissions compliance. It monitors exhaust temperatures, DEF dosing rates, and DPF soot load levels to ensure the aftertreatment system operates correctly.
Common Engines Using ACM Modules
- Cummins ISX, X15 and ISB 6.7 engines
- Detroit Diesel DD13, DD15 and DD16 engines
- Paccar MX‑13 and MX‑11 engines
- Volvo D11, D13 and D16 engines
- Mack MP7, MP8 and MP10 engines
- International A26 and MaxxForce engines
Common Signs of ACM Failure
- DEF or SCR system fault codes
- DPF regeneration problems
- Emissions warning lights
- Engine derate conditions
- Communication faults with emissions components
Programming Requirements
Many ACM modules require programming or calibration before installation. Proper software configuration ensures communication with the ECM, DEF system, and exhaust sensors.
