I had my battery (Interstate) replaced at Firestone and I noticed the Bit Serial Data Interface wire was not connected. Where is this supposed to be attached?

A
The BSD wire harness should be permanently affixed to the IBS (Intelligent Battery Sensor) at the negative battery cable. The wire will have a small harness plug that is connected to the corresponding harness plug which leads to the ECM (Engine Control Module). So, if the harness plug is disconnected, you need to find the corresponding plug which should be somewhere in the area. If the wire itself is disconnected from the IBS unit, it has been broken and the battery installer should be responsible for this. The fix is to replace the negative battery cable assembly.
問題可大可小，文中有提到可以檢查電池端的BSD接頭是否有接好，若接頭都有正確連接還是出現錯誤則必須更換BSD線組

Hello Showtall Sir,

You are right !!
的確在電瓶附近有一條BSD線組,當時有檢查過,而且也將電瓶斷電過,情況一樣
也有猜測是否BSD線組壞掉,但是因為經過我前一封敘述所做的測試是可以傳送資訊,再加上一條BSD線組報價一萬多,所以沒有換.....
不管如何感謝您的幫忙,謝謝!!

我如果是你,會考慮先換 1萬多的BSD線組來試. 原因 1. Error Code . 2.有類似case. 最重要的是先換9萬多的行車電腦來try. 結果error 一樣不行消那你要改try 新BSD線組嗎? 如果可以借到行車電腦先試試最好了.. 或是新BSD線組.. 不明原因要try 通常都是從便宜的先換.

Thank you shakechen !
如果真要檢修也的確是會從便宜的開始,只是條BSD線組也不便宜
感謝您!!
