If you're interested in the technical side, I can help you with: Explaining specific UDS Service IDs (like $10 for Diagnostic Session Control) Drafting a technical summary of the CAN transport protocol (ISO 15765-2) Writing more cyber-thriller stories based on real-world protocols How would you like to proceed?
ISO 14229 is a communication-agnostic diagnostic protocol defined for road vehicles. Unlike earlier standards tied to specific physical layers, such as ISO 14230 (KWP2000) or SAE J1850, UDS operates independently of the underlying bus system. It can be implemented over Controller Area Network (CAN), Ethernet, FlexRay, or LIN. This flexibility allows manufacturers to adopt modern high-speed networks while retaining a uniform diagnostic command set. The standard defines a client-server model where an external test tool (client) communicates with one or more ECUs (servers) using diagnostic requests and responses. iso 142293 pdf
