汽车的总线引出线是否可以不同?
Does can bus pinout differ in cars?
我正在研究 CAN BUS 和 CAN 协议。我想知道,每个车型在 OBDII 端口上的引出线是否不同? 或者所有汽车都一样吗?
P.S。如果不同,是否有对应的数据库?
OBD-II is an improvement over OBD-I in both capability and standardization. The OBD-II standard specifies the type of diagnostic connector and its pinout, the electrical signalling protocols available, and the messaging format.
