CAN Bus Explained: A Simple Intro (with OBD2 and J1939)

Technical guide to the CAN bus that carries data between a vehicle's control units, extending into OBD2 and heavy-duty J1939. Covers physical wiring, frame structure, bit-level decoding and data logging, so network faults and scan-tool readings stop being opaque. Fills the gap every shop-floor electrical resource leaves: modern faults are as often network problems as broken wires.

Electrical Engineering Portal (EEP)

Practitioner-run technical site publishing articles and guides on power engineering: substations, switchgear, transformers, protection relays, cables, grounding, motors and low- and medium-voltage installations. Readers build working knowledge of how industrial and utility electrical equipment is specified, operated and protected.
