I have a 2004 4.0 4x4. Obd2 port isnt working. Replaced the cig lighter fuse so the port has power and ground but it's still not connecting. Anybody point me in the right direction for troubleshooting?
 
Ok, pin 1 is at the top (wider), left hand. Pin 8 is the top right hand. Pin 9 in the bottom (narrower) left hand. Pin 16 is the bottom right hand.

What is the resistance between pins 6 and 14?
 
Maybe your scanner sucks...
 
Wonder why it blew the fuse, you sure it still has power and the fuse is still good? Could have a wiring problem
