1. J1850 PWM (Ford)
2. J1850 VPW (GM)
3. ISO9141-2 (2004~2008 Europe)
4. ISO14230-4（亦名 Keyword Protocol 2000）
或是更新⼀些的 ISO15765-4/SAEJ2480（即 CAN Bus）
美製⾞廠直到 2003 年才獲准採⽤ CAN，但是在 2008 年之後，所有的⾞款都採⽤了
CAN 協議。
符合 OBD-II 標準的汽⾞可能會採⽤五種通訊協議標準其中之⼀：

18. ELM327
• The ELM327 abstracts the low-level
protocol and presents a simple interface
that can be called via a UART, typically by a
hand-held diagnostic tool or a computer
program connected by USB, RS-232 or
Bluetooth.
