ECU 고장? 차문제..
BMW F10 520d ECU 고장❓
적은 항상 가까이에..
DME 분사장치 (Cylinder 1,2,3,4)
트리거링 단락 / Short Circuit
단선 / Open Circuit 고장코드 발생⚠️
ECU 문제가 아니라 차량 하네스, 배선, 접지(Ground), 전원라인 문제도 많습니다.🔍
⚡ Short to Ground
⚡ Short to B+
⚡ Open Circuit
⚡ Injector Trigger Fault
고장코드만 보고..
인젝터 교환 ❌
ECU 교환 ❌
Fault Code ≠ Parts Replacement
근접 배선 손상, 오일 유입, 커넥터 접촉불량,
엔진진동으로 인한 Harness Damage
이런 원인들도 많습니다.
Think one more step.
조금만 더 생각해볼 때입니다.🧠
정확한 진단이 먼저입니다 ✔
Diagnosis First, Replacement Later.
