- 차(베뉴)에서 측정한 CAN 트레이스 (blf 파일)을 분석한다.
진단 요청과 응답 메시지 아이디들의 짝을 찾는다.
- 표준에 따르면 진단 메시지의 아이디(m_id)는 0x700에서 0x7FF로 정해져있다.
- 표준에 Read ECU ID, Read DTC 등 몇몇 서비스는 대부분의 제어기들이 응답한다.
- 위 두 가지 사실에서 착안하여 m_id를 0x700에서 0x7FF까지 순차적으로 증가시키면서 (스캐닝) Read ECU ID, Read DTC 등의 서비스를 요청한 후, 0x700번대 응답 메시지를 500msec(응답 대기 시간) 동안 기다린다.
- 응답 메시지가 있다면, 그 메시지의 m_id를 요청 메시지 m_id의 짝으로 판정한다.

노트
- Read Software Version 요청의 응답은 모두 부정 응답이다.
- 나는 표준(Standard)/기본(Default) 모드/세션에서 Read Software Version 요청을 하였다. 모드/세션이 맞지 않아서 부정 응답을 했을 수도 있고, 지원하지 않는 서비스라서 부정 응답을 했을 수도 있다.
- 부정 응답의 이유 코드가 0x12, 0x31, 0x22, 0x11로 다양하다.
결론
- 진단 요청 스캐닝으로 진단 요청 m_id와 응답 m_id 짝을 찾을 수 있다.
- 진단 요청 스캐닝을 통해서 남의 요청에 응답하는 제어기가 없음을 검증한다.
