Sure, here is a guide to help and you should check the fuse # 44 in the under-hood fuse panel. I would also try the scanner on a different car to make sure it works. I have included the ALDL connector wiring diagram as well so you can see how the system works.

Check out the images (below). Please let us know what happens. Please make sure the connector is free from corrosion as well.
