I am interested in what information my Mazda 2 (2015 DL) can provide over the OBD2 port. As such I have been doing some reading and have purchased not only a couple of cheap OBD port readers, but also a breakout (LED indicator box). As part of my reading I took a photo of the OBD port on my car, to check what pins are populated.

Now there was no real surprises;
  • Chassis and signal grounds. (4 & 5)
  • Bat +. (16)
  • High speed CAN. (6 & 14)
  • Low Speed CAN. (3 & 4)
  • ISO 9141-2. (15)
Except;
  • Pin 8 is populated.
I am wondering what the function, if any is pin 8 used. According to the OBD spec its vendor specific. Is this used? If so what is its function.
