High-Speed Machine Communication Network:
This is a critical function for the 320D. The chassis harness contains the wiring for the CAN (Controller Area Network) data links (typically CAN A and CAN B).
This network allows high-speed communication between the Engine ECM, Pump Controller, Monitor in the cab, Gate Lock Lever Solenoid, and other smart devices. This integration is the core of the 320D's renowned fuel efficiency and responsive performance.
This 291-7589 chassis harness is used for 320D 323D C6.4 3066 excavator.
