CAN Bus Reverse Engineering: Control Real Car Dashboard

Welcome to this practical course where we will reverse engineer a car's dashboard system without having any documentation.Our mission is to take control of certain dashboard functions — such as turning blinkers on/off and changing the displayed vehicle speed — using CAN Bus communication.We’ll go step-by-step, from connecting to the car’s electronics, analyzing the traffic, to writing custom CAPL scripts and creating a virtual dashboard replica.By the end of this course, you will gain a deep, practical understanding of topics such as:Identifying the correct CAN pins on a vehicle connector, even when there is no schematic or pinout available — using methods like continuity testing and trial analysis.Determining the correct CAN bus speed (baud rate) using Logic analyzerCapturing and analyzing real CAN bus traffic to identify frame IDs associated with specific dashboard actions — such as blinkers, speedometer updatesDecoding message payloads, by interpreting the bit-level structure of the data fields inside CAN frames and understanding how individual bytes represent physical values.Using CAPL scripting in the Vector toolchain (such as CANoe) to simulate and test message injection,Building and refining a DBC file, which is a powerful way to describe and simplify the interpretation of CAN frames, making the data readable and easier to work with.Creating a virtual dashboard replica, allowing you to visualize and control the dashboard behaviorThis course is designed for a wide audience, including:Automotive reverse engineers who want to dig into vehicle internals and uncover how systems communicate.Embedded software and hardware developer
