Cars have long relied on a relatively simple network standard called the CAN or Controller Area Network bus. The CAN bus coordinates all the microprocessors and electronic control units, or E.C.U.s, that need to trade engine, powertrain, and diagnostic information, transmitting details like transmission status and fluid levels. As more electronics like window and seat controls were added to cars, the CAN bus was tweaked over the years with additional local interconnection networks, or LINs, to handle the swelling communications load.
