Circuit Description

The communication among modules is performed through the class 2 and high speed GMLAN serial data circuits. The modules that need real time communication are attached to the high speed GMLAN network. The body control module (BCM) is the gateway between the networks. The purpose of the gateway is to transfer information from one network to another. The gateway will interact with each network according to that network's transmission model. Refer to Body Control System Description and Operation  for more information about the gateway.
