난이도 & 준비물

난이도 쉬움⏱ 예상 60~120분🔧 전용 진단기

증상

제어 유닛에 연결된 회로의 단락 현상. 퓨즈가 끊어지는 단락과 부품이 동작하지 않는 단락 두 가지 종류 존재. 제조사 제공 진단 방법 중 제어 유닛 연결 회로 진단 절차 진행 중.

처리 내용

끊어진 퓨즈에 집중하여 해당 회로를 진단할 것. 메인 퓨즈는 무시할 것. 제거한 퓨즈 양쪽에 디지털 멀티미터(저항값 20MΩ 이상)를 연결하면 고저항으로 인해 초크 포인트가 생성되어 단락을 감지할 수 있다. 캐패시터가 포함된 부품 연결 시 미터 읽음값이 올라갔다가 서서히 감소하는 것은 정상 현상이다. 실제 단락 발생 시에는 지속적인 전압 읽음값이 표시된다.

Brief history:I was thinking about buying myself a fun sports car, there's nothing new in the £50-80k range I would particularly be interested in. Had to feel special, had to be light, "analogue" and not overly-assisted. Had to be manual and i prefer a large capacity NA to forced induction. Ford Mustang maybe, perhaps not quite special enough and a bit porky. Emira - I love Lotus and have had a few but i'm not a fan o

After writing off my BMW 320d halfway through the month, I suddenly found myself in the market for a new car.Once the insurance payout landed, I had just under £5,500 to play with after paying my excess. I spent hours trawling AutoTrader trying to find the right replacement.I'd lined up a BMW X5 that was slightly over budget and was due to view it today... only for it to sell yesterday before I got the chance. Frustrating, but that's just how it goes.I kept looking, but nothing else really grabbed me.Then I spotted a Range Rover Sport on AutoTrader just five miles away. I called the dealership
