大家好
在下的2005 Corsa C 1.4 MTA,煞車燈內側紅燈殼熔出一個缺口會漏白光,
今日試裝號稱能解碼不產生故障碼的紅光LED 後煞車燈結果:
1.不開燈+踩放煞車→燈具正常作動
2.開燈→燈具正常作動
3.開燈+踩放煞車→燈具正常作動但是"儀表亮F"
4.一邊LED一邊鹵素→任何狀態下燈具皆正常作動
注:原鹵素燈規格為p21/5W 1.75A/0.417A
LED規格為3W 0.25A/0.05
推論:
a.只有全載(開燈+踩煞車)時偵測電流是否正常
b.依據結果4.,(電流>0.25A+1.75A=2A)=電腦判斷燈泡沒燒=正常
結論:
I.這樣好像改成兩邊加起來總共24W的LED,電流對就OK了?
II.感覺號稱能解碼的只是增加LED提高負載,把整體電流衝高而已?
以上若有錯誤,懇請不吝指導,謝謝大家^^
