central gateway module
gateway is the core of eea and vehicle networks. as the data router of network, gateway connects all the can networks and some lin networks. it translates and transfers information going through these networks. as a diagnose router, gateway is the only diagnostic interface of the vehicle connecting to external testers. gateway also works as a center node of the vehicle network. it monitors and coordinates the vehicle network operations and electrical parameters.
