Unit powers up fine with USB, downloaded updates via PC.
Went out to the Bronco to plug it into the OBD2 to backup the original tune, and the programming unit is dead. Can't get it to power up.

Plugged in an OB scanner just to check the Bronco has power and functioning, and it all seems fine.
Double checked on the PC that the unit still functions... It's fine.

Anyone else have any issues with the cable by any chance? Any odd fitment? The pins look pristine. Really nothing out of the ordinary that I can see.

Yes, had same problem with unit ordered and received in August. Dealer happened to have another cable for a recent F-150 install, so they used that cable and finished install.

Had you tried to power up, or it was something they found?

I'm a little concerned they'll tell me to get lost because I powered up at home (even though I wasn't going to program yet).

Just wanted to register it to me after hearing of some who couldn't upgrade because the dealer used their account.
