EMS2000 CAN Communication

The EMS200 control unit primarily communicates to other modules via bus communication. Very few signals are sent from one control unit to another via hard wired cables. Usually any extremely important signal is going to hardwired between modules. (ex. MRS control unit crash signal to EMS2000)
