I used this with a fee app from app store (there are many, this is the one I used first and it worked). Had taillight, signal, brake lights problem with my 2012 F 150 and after months of trouble shooting, figured it was the BCM (body control module). Scanned it. Some codes came up. None of the codes said anything obvious about the BCM having issues but as soon as I cleared the codes, my problem no longer existed. THANK YOU for this product so I didnt have to go get "screwed" by the dealer. I've read threads from guys with what seemed like my same issue who ended up spending $800 at the dealer because of course the dealer wants to replace everything. F that.

Not working. Could never get it to work. Cheap knock off.

Its hard to simply understand
