SCAN TOOL NOT COMMUNICATING WITH VEHICLE (OBD II PORT & DATA LINK CONNECTOR NOT WORKING)

TRY ANOTHER SCAN TOOL

I had to take the whole obd port on the car apart once and tighten up all the connectors

Another thing to keep in mind, if car is not getting 12v or up, some commands from scan tools wont execute, in my experience
