This is Buick Motor Division’s first explanation of networking and how it functions. The very sophisticated network consisted of the ECM (PCM), Body Control Module (BCM), Heating Venting Air Conditioning (HVAC) module, Instrument Panel Cluster (IPC), central power supply (CPS), Cathode Ray Tube (CRT) interface, and the sub modules. It would benefit any mechanic to read for comprehension this book as it walks the reader through a very through understanding of network communications.
GM PST 10486.01-1
Coverage: Body Control Module / Port Fuel Injection
Chapter 1 introduces voltages and how computers interpret signals from voltages applied. It explains the differences between analog and digital communications.
Chapter 2 discusses the BCM functions, analog to digital converters and sequential sampling, This is followed up with circuit identification.
Chapter 3 discusses the ECM (PCM) description, functional operation, service identification, and how it is used to control all previous versions of component control. It then advances into charging, fuel, and cooling system control.
Chapter 4 introduces the Instrument Panel Cluster (IPC), Central Power Supply (CPS), and the integration into the computer network. This is followed up with an explanation of the CRT interface into the computer network.
Chapter 5 provides an introduction into climate control operation and inputs provided within the network.
Chapter 6 introduces the components controlled by the BCM, such as the Chime module, headlights, twilight sentinel, illuminated entry panel dimming. Cruise control, and retained accessory power
Chapter 7 is about system diagnosis using the self test features of inputs, outputs and override function.
Product Service Training
These books are easy to understand, and applicable to a single subject. The book information is more in depth than even their own service manuals. The books include the original mechanic's notes and we strongly suggest that you read those notes with great care!
These books were never distributed outside of the manufacturers product service training channel.
