LIGHTING SYSTEM - SYSTEM DIAGRAM

Various switches or sensors are represented as inputs for the different systems mentioned in the section. Where direct electrical connections do not exist between components, signals may be carried across the different networks (BEAN, CAN) that exist on the vehicle. If a signal needs to travel from the CAN network to the BEAN network, the gateway ECU allows the signal to travel between these different networks. Some of these different signals can be confirmed or inspected using the intelligent tester.
