[DoCAN] Vehicle Diagnostic Communication Part 1 [Overview]
The typical standards for vehicle diagnostic communication are ISO 15765-2 and ISO 14229-1.
Depending on the manufacturer's policy, the standard number may be a requirement rather than a specific requirement.
The layers of vehicle diagnostic communication can be represented by the OSI model.
There are two main axes of vehicle diagnostic communication.
UDS and OBD.
OBD is referenced by vehicle emission regulations, so the various parameters are clear.
UDS only has recommended values, and the actual values are dependent on the finished vehicle manufacturer.
