Figure 8. Motor Control Module
The MCM processes the data received from the CPC, for example the position of
the accelerator pedal, engine brake, etc. The data is evaluated together with the data
from the sensors on the engine, such as coolant and fuel temperature, and oil
pressure. The data is then compared to the characteristic maps or lines stored in the
MCM. From this data, quantity and timing of injection can be calculated.
Aftertreatment Control Module
The ACM is located on the back side of the Aftertreatment System (ATS) (see
graphic below).
