開箱-平民版Tech-2: ELM327 OBD2藍牙讀取器
» 發佈日期:2010-04-27


拜電子科技的發展,以往只有專業保修廠會購入昂貴的專業檢修電腦,例如SAAB車系使用的TECH-2,
對於熱血一拜的車友,除了在拍賣或歐美汽車零件商買壹台TECH-2,現在又多了許多評價的選擇,
其中最為車友們熟悉的,當屬VAG車系的VAG-COM。

最近在01上拜讀「mobilesmith」網友po的兩篇文章:
Legend 利用 Torque 軟體當作 OBD-II 車輛診斷系統暨HUD還有軌跡紀錄
OBD-II 汽車診斷系統討論

得知有一個平價的solution,透過TECH2介面讀取器,以軟體進行ECU資訊的解碼,
當下立刻在大陸拍賣網站拍下今天的主角:「ELM327 OBD2藍牙讀取器」

此款藍牙讀取器,是使用 Elm Electronics 這間公司所生產的型號327 IC晶片,進行OBD資訊的讀取

此款晶片基本上支援 ISO 15765-4 CAN, SAE J1850 PWM, SAE J1850 VPW, ISO 9141-2, ISO 14230-4 and SAE J1939 等幾種protocols的解譯,原先是設計用來轉接到RS232的介面,
現在網路上則出現了藍牙應用的solution,透過藍牙虛擬的com port來達成無線連接的目的。

******************************************************************

在下拍後,等待兩天後(大陸的快遞業者假日不送件)
今天文章的主角ELM327 終於送到手上


坐飛機過來的


超簡單的「工業包裝」


打開包裝,只有藍牙讀取器本體,用塑膠夾鍊袋裝了
本體上有幾個狀態指示燈
ps. 光碟因為通關考量,所以賣家出貨時就沒附,車友可以自行跟賣家協調用其他方式傳遞


背面

接口特寫


9-3的OBD2接頭在方向機柱右下方


連接時,鑰匙需保持在ACC關閉
接好後,讀取器會亮紅燈


接著在電腦上可以透過藍牙搜尋到名稱為「CBT Dev B」的裝置,
該設備預設之配對密碼為『1234』
請注意!與常見的0000不同!

完成配對後,就可以開啟ODB2 scan tools的軟體,進行資訊讀取。
網路上有相當多的OBD2 scan tools,以下先用一套freeware進行簡單的示範,
軟體名稱為ScanTool.net 1.2,可以提供簡單的OBD2資訊









以下摘錄OBD2可以提供的資訊項目 (但會因車廠車型與軟體能力,不一定都show的出來)
