CAN Bus (Controller Area Network)
A communication system that allows multiple ECUs to share information efficiently.
The CAN Bus is the digital backbone of modern vehicles, connecting control units such as the ECU, TCM, ABS, and airbag module. It enables high-speed data transfer, reducing wiring complexity. Diagnosing CAN faults involves checking voltage, termination resistance, and waveform integrity. Problems may cause communication errors or system shutdowns. Understanding CAN structure is vital for advanced diagnostics and retrofitting new systems. Specialized tools, like CAN analyzers, help visualize and decode network traffic.
