Techinical Info
The spare part with OE code A0004463454 is the ACM2.1 (Aftertreatment Control Module) which manages the SCR/AdBlue system of Mercedes‑Benz Actros MP4/MP5 Euro 6. It controls urea dosing, NOx and temperature sensors, pump, injector and communication with the MCM/CPC over the CAN network. The ACM2.1 control unit is connected via the CAN (Controller Area Network) to the MCM (Motor Control Module) and the CPC (Central Powertrain Controller).
This network exchanges in real time information such as engine speed, fuel flow, load, temperature and vehicle status, which are needed to calculate how much AdBlue to dose.
In practice: the ACM receives data from the engine (MCM) and returns the status of the SCR system, as well as reporting any faults or degradation conditions. The manufacturer is Continental.
Technical specifications
- Platform: ACM2.1 (Continental)
- Functions: SCR control, AdBlue quality/pressure monitoring, dosing control, heating/line management, dedicated diagnostics
- Interfaces: powertrain CAN with MCM/CPC, inputs for NOx/temperature/pressure sensors, pump and injector actuators
- Mounting: cab compartment/frame (version for Actros MP4/MP5 Euro 6)
DIPA can intervene to overhaul these parts thanks to its experience and expertise.
Functions
- Calculation and control of urea dosing based on flow rate and NOx
