changed the title
Add the UDS service 0x14 (ClearDiagnosticInformation) to enable requesting clearing of DTCs. The actual clearing of DTCs is project-specific and must be provided by the integrator separately. This commit therefore adds only: * a demo implementation of the service in the library which handles: - groupOfDTC 0xFFFFFF (all DTCs) returns a positive response - any other group returns NRC 0x31 (requestOutOfRange) - the fixed request length of 4 bytes is validated by the framework * registration of the service in the reference application * unit tests covering the supported groupOfDTC cases
