• Aftertreatment Control Module (ACM)
• Transmission Control Module (TCM)
The four control modules are connected by a proprietary datalink through which all
necessary data and information can be exchanged.
Common Powertrain Controller
The CPC is typically located in the cab, behind the dash (see graphic below).
Figure 7. Common Powertrain Controller
The CPC communicates with other control units installed on the vehicle including
the MCM, the ACM and the TCM (if equipped) over the data link. Data for specific
applications is stored in the CPC. These include idle speed, maximum running
speed, and speed limitation. From this data, instructions are calculated for
controlling the vehicle and transmitted to the CPC via the proprietary datalink.
Motor Control Module
The MCM is located on the left-hand side of the engine (see graphic below).
