U1412 and other codes after tire size change with Snap On Solus Edge.

[HDR]

I installed 35" tires and changed the tire size in mm to 2768 with my Solus edge and now have U1412 abs and other codes. When I finished changing the tire size it side to do a ABS Initialization procedure which I can't find. Any ideas?

It could be the lack of initialization, but compare the wheel speeds in the ABS module to the speed in the BCM or PCM. It does not specifically, but I suspect it is seeing two different vehicle speeds.

Still need help on this. Does anyone have a idea. Also I know my axle ratio is 3.42, but is there any way it could be different?

I has able to get rid of U1412 and now I have U1439!!!

Any chance I don't have 3.42's?

Pull the build sheet, it tells you which ratio you have. At least what was installed in the factory...

What is your rpm in 6th at 60mph?

I bought the truck new and the sales sticker say 3.42's. I dont know if there is something else I need to calibrate after the tire size change like I have to do with the ABS system?

The Drive Train Control Modal say the axle ratio is 3.55 and when I looked at the transmission data it say the axle ratio is 3.92.

I took it to a dealer to day and they told me that there isn't anything they can do to clear the U1439 code because of the tire size change! Has anyone used Alpha OBD on a 2018 3500 with the aisin transmission? ANY help would be appreciated. Thanks.

Sure does, you will need the security bypass cable.

It's found at a lot of places, some are lacking stock.

I got mine I think at Morris 4x4.

They are all pretty nice typically.

Alpha works, I have not changed tire size.

Lots of videos.

Did you change the RPM (rounds per mile) in the ABS unit according to the tire size? Buddy of mine had the same problem, he played around with tire size and messed all up. Then he changed RPM and all was good.

No I don't do that. I'll give that a try.
