6.1 OVERVIEW
Key components of the CPC system are the serial communication links SAE J1587 and SAE
J1939. Using these communication links allows CPC to offer the following functionality:
□ Transmitting sensor information from the MCM via the data link at regular intervals and/or
upon request to obtain data and to monitor for failures
□ Sharing information between stand-alone modules used in the system via the data link
□ Sharing engine data with electronic dashboard displays and vehicle management
information systems via the data link
□ Transmitting and performing diagnostic procedures from external instrumentation such as
the hand-held diagnostic data readers or DDDL via the data link
□ Transmitting customer requested changes to the CPC from external instrumentation via the
data link
□ Transmitting to the powertrain the messages assigned to both the engine and the
transmission retarder.
