yes i agree there is a prob wireing or someone said maby a fuse
if there is a fuse that would disable the obd2 port how do i find it
i bought this autel so i could monitor my 2014 ram promaster and it worked the first time
but now no connection i notice when i incert the MaxiVCI Mini adapter to the car i get no power light whitch makes me think fuse
it works fine on friends car and the power lite comes on when i incert the maxiVCI Mini
