Troubleshooting a communication error in a vehicle communication network.

Communication errors in a vehicle communication network can affect the performance, safety, and functionality of various systems and components. A vehicle communication network is a collection of electronic control units (ECUs) that exchange data and signals through a common protocol and physical medium, such as CAN, LIN, or Ethernet. Troubleshooting a communication error requires a systematic approach that involves identifying the source, type, and cause of the error, as well as applying the appropriate corrective actions. In this article, you will learn the best practices for troubleshooting a communication error in a vehicle communication network.

What is CAN System?

A controller area network (CAN) bus is a high-integrity serial bus system for networking intelligent devices. CAN busses and devices are common components in automotive and industrial systems.

The Controller Area Network (CAN bus) is a message-based protocol designed to allow the Electronic Control Units (ECUs) found in today's automobiles, as well as other devices, to communicate with each other in a reliable, priority-driven fashion.
