Mercedes Technical Document 문서로 Fuel Trim 값 분석시 사용하면 좋다. LTFT은 아이들시 1.0msec. STFT은 부분.풀 부하 +-32%이내 인젝션기간 을 기준으로 한다. DTC는 +-25%에 발생하는거 같음. 메모리는 KAM에저장되며 10Trips이 요구되어 진단됨.
차량별 특징이 다르니 점검차량이 맞는지 부터 체크한다.
점검항목은 아래를 포함해서 진행한다
- Intake air leaks
- Injector defects or carbon build-up,
- Air Flow Sensor defects
- Pressure regulator defects, such as a blown diaphragm.
- Fuel tank purge control valve defects or EVAP system leaks.]
- EGR defects
- Vacuum leaks of any kind.
- Mechanical engine wear, such as, chipped valves or leaking rings
