cant read codes

The check engine light came on the other day so I hooked up my obd2 code reader but it wont link with the van. My code reader works with all my other vehicles. Im not sure what to do next.

This fuse also feed the cigar lighter so check to lighter in first and if not working go to the fuse #17 (probably burnt).

It is a 2000. I just went and checked and fuse 17 was burnt. I replaced it and now its woking. Thank you.
