Terminating resistor j1939 freightliner
Web29 May 2024 · The second terminating resistor is built into what's called the *MMDC* on our coach. The MMDC is a Multi-Module-Data-Controller or, a small computer if you will. For some odd reason, Freightliner decided to put that $2 resistor inside a $450 component (MMDC) . If that $2 resistor goes bad, you have to replace the $450 computer or MMDC.

WebCAN bus physical & data link layer (OSI) In more technical terms, the controller area network is described by a data link layer and physical layer. In the case of high speed CAN, ISO 11898-1 describes the data link layer, while ISO 11898-2 describes the physical layer. The role of CAN is often presented in the 7 layer OSI model as per the illustration.
