This engineering-focused forensics curriculum provides a deep dive into vehicle communication networks, moving beyond basic diagnostics into the physics and logic of the Controller Area Network (CAN). You will master signal analysis, including dominant and recessive states, while learning to dissect 11-bit and 29-bit frames to reconstruct vehicle telemetry. The course covers ECU intelligence, Diagnostic Trouble Codes, and the mechanics of chip tuning to identify firmware modifications that alter vehicle behavior. A central focus is hardware interfacing, teaching you to use ESP32 or MCP2515 modules for non-invasive bus sniffing. Using industry-standard tools like Wireshark and SavvyCAN, you will analyze real-world traffic from vehicles like the 2010 Toyota Prius to decode complex protocols. This training establishes a complete forensic workflow for modern automotive incident response and digital investigation.
