Introduction
The purpose of the OTX DiagCom extension is to provide the necessary OTX elements for performing diagnostic vehicle communication. Specifically, the following diagnostic use cases have been considered:
- Handling of ECU communication channels
- Execution of a diagnostic service
- Setting of service request parameters and evaluation of service response parameters
- Dealing with positive or various negative responses of a diagnostic service
- Handling of communication channel protocol parameters
- Performing variant identification of an ECU
- Functionally addressed diagnostic services: more than one ECU will respond to a request
- Repeated/cyclic execution of diagnostic services: a single request will result in multiple responses from the same ECU
- A potential combination of functional addressing and cyclic service execution: multiple ECUs responding multiple times to one request
- Complex data structures within the requests and responses of diagnostic services: structures of parameters, lists of parameters, lists containing structures of parameters
