When i plug my V2 into my OBD II port it does not start up it says no connection to ECM tried it on two different trucks same thing. I am thinking it will need to be repaired, But was wondering if anyone else had this problem?
Ignition in the RUN position but engine not running.
Cigarette lighter fuse tested good.
Correct driver and firmware for the version of software you are using.
I tried it on two different trucks and it does not even power up till i plug in the laptop. I just used it on the same truck last week so i don't think its on the truck end but i will check the fuse anyway Thanks Pat
