Hello,

It looks like the data link connector should be fuse 13 in the underhood fuse block on the left side of the engine compartment. Please see the diagram below.

Here's a link to OBD2-code definitions:

This video guide gives some tips on what to do when the OBD-2 port isn't working:

Thanks, Wendy W.
