Hey guys.. I think Jscan is the recommended scan tools for wranglers. My only issue is that to get full capability you need to purchase a license for the VIN. I want to have a tool that I can use that's not VIN specific that I can use when inspecting jeeps that i'm considering purchasing. I'm a newbee with this stuff.. but want a tool that allows me to see if codes have been cleared or if the battery was disconnected to clear a code.. and the vehicle is not ready for emissions testing. Also, I'd like the tool to indicated coolant temperature instead of the gauge. Not sure what other things I should also be checking with the tool when inspecting. Thanks for any advice !!
