I bought the Smarty several months ago and installed it with no issues on my 2005 Dodge. I decided this morning to return it to stock to see if it would hurt or help my fuel mileage. When I tried to install the return to stock at 63% I get he error 42 message. I read the manual and tried the self correct diagnostic tool in the smarty but it continues to receive the error message every time. Naturally the truck will not start it just site there and the fuel pump and relay surges. Can you help or is the a dealer issue. Just so you know the truck has been fine until this was attempted. Thanks for any help.

Would it help if I took the fuel pump fuse out while loading the program because of voltage or anything?

The dealer will only cost you big time.
You need to give Bob Wagner a call. Smartypower.com | Home Of The Smarty | Contact

if you have a fass pull the fuse, you can also pull the abs fuses.

you have a communication error

Thanks a lot the Fass fuse was causing low voltage I guess. Took it out and it worked just fine. Thanks again
