I went to have my emmission test done and the shop could not do it, they claim a problem with the connection, the dealer ship said to replace the Data Link Fuse. Unable to locate the Data Link fuse on the fuse panel, can you tell me which fuse it is.

The Cigar fuse in the under hood fuse box supplies power to the data link connector.
...goes on and off. I had the engined checked with that machine and they said first thing is the emmissions area needs a part. I am more concerned about the brakes.
