The Diagnostic Communication Manager (Dcm) is a Basic Software Module of the Communication Services.

It is in charge of the communication path and execution of diagnostic service resulting in the processing of diagnostic requests from an external tester or onboard test system. It forwards requests coming from an external diagnostic scan tool and is further responsible for assembly of response messages (DTC, status information, etc.) which will be transferred to the external diagnostic scan tool afterwards.
