I do know about why the engine should run bit, but thanks. Its good to know you can shut off between downloads. The cut engine/charge battery option would also work during the process. Once the installs complete, leave the cables connected to crank up the engine.

 

Just updated our 2011 QX using a battery charger...that what the dealer told me to do. They said to use either maintain or slow charge. That truck kills batteries and I made it through...lol
