CONTROLLER AREA NETWORK (CAN)
Previously, for different computers in the vehicle to share
the same information, each signal required a different pin
and wiring. However, with the introduction of a CAN sys-
tem, only two lines are required to achieve the same func-
tion. The information is in digital format. This method does
not use an integrated ECM.
