OB2 port not working?

Hi,

As far as the power supply is concerned, it comes from fuse 17 in the central junction box. At the connector itself, pin 16 should have power at all times. Check that the fuse is good.

Additionally, make sure there is power to and from the fuse as well.

Also, I attached the wiring schematic below of the OBD circuit so that you have a reference.

Let me know if this helps or if you have questions.

Take care,

Joe

See pics below. Note: I had to cut the schematic in half to make it readable. I overlapped the two so you can follow from one to the next.
