난이도 & 준비물
증상
'94 올즈모빌 브라바다의 디지털 대시보드가 작동하지 않음. 계기판 퓨즈에 전원이 없지만 패널의 다른 모든 퓨즈에는 전원이 있음.
처리 내용
온라인에서 'oldsmobile bravada wiring diagram'을 검색하여 배선도를 찾으세요. 퓨즈 패널 회로도를 확인하여 계기판 퓨즈의 전원 공급처를 파악하세요. 두 가지 가능성이 있습니다: (1) 다른 모든 퓨즈와 같은 공통 버스에서 전원 공급, (2) 부하 감소 릴레이 앞의 ECU 전원 등 별도로 공급. 같은 전원에서 공급받는 다른 퓨즈들을 확인하여 전원이 있는지 테스트하세요. 전원이 있으면 퓨즈 블록 자체의 손상을 의심하세요. 없으면 전원 공급처의 문제를 진단하세요. 빠른 테스트로 퓨즈 패널의 다른 부분에서 계기판 퓨즈의 핫 측(부하 제외)으로 전원을 연결하면 전원이 공급될 경우 대시보드가 작동하는지 확인할 수 있습니다.

BMW 5시리즈
Go woke go broke. What's the point of Jaguars USP when any old Chinese EV maker can give you a super smooth 500bhp car with effortless torque and eery refinement for under £50 grand? When Tesla gives you much the same with the added benefit of a luxury charging network? Would it just be beauty?That's about the only thing they could possibly conjure as a point of difference but I doubt they can comply with a myriad of technical parameters for a global car AND make something gorgeous looking. The only way of making something quite different would be to not package the battery as a skateboard
