I don't know who made those diagrams, but I don't agree with them. My truck has class 2 and it is computer networking. CAN came out after that, some 04 GM models (malibu/G6) were 1/2 and 1/2 CAN and class 2.
Open the door on my truck with the key in the ignition and the chime comes out the speakers. The BCM knows the key is in and the door is open, sends signal to radio to chime.
The purpose of computer networking is to reduce redundancy and the amount of sensors on a car, also reduce cost.
My 81 Malibu and 84 Z28 both had 2 coolant temperature sensors, one for the computer and one for the gauge/idiot light. With computer networking, only one sensor and wiring is needed, the computer and gauges share the info over class 2 or CAN.
