Frequently asked questions
Which OBD-II pins carry CAN-H, CAN-L and power?
Under the standard OBD-II (SAE J1962) pinout, pin 6 is CAN-High, pin 14 is CAN-Low, pin 16 is battery positive, and pins 4 and 5 are grounds. Verify the connector wiring before connecting.
Does this module include a CAN transceiver?
The listing describes it as a breakout module that exposes the bus lines. To read or write CAN frames you still need a CAN transceiver or interface on the other side, such as a microcontroller with a transceiver.
