The first thing I need you to check is fuse 1 in the interior fuse panel. If you look at pics 3 and 4, it shows the location and the components it powers.
In addition to checking the fuse, it is important to check for power to and from the fuse. A fuse before it may have failed and there may be no power supply being provided.

If the fuse is good and has power, go to the data link connector where you plug in the scanner. Pin 16 should have 12v at all times. I need you to confirm that. If there is power, check pin 4 for continuity to ground. See pics 1 and 2 below) Here is a link you may find helpful:
Let me know what you find or if you have other questions.
See pics below.
