Abs Failure After Install 35's Tires

[alexcobb]

Hi Guys

 

The ABS and brake light came just after install new 35's tires.

 

My truck is a 2007 (new body) 1500 sierra.

Not unusual. It needs to be re calibrated for your tire size.

Hmmm. Didn't have that problem.

Didn't you reprogram yours with the predator?

I lifted with the Rough Contry 7.5", replace gears with 4.88's, replace tires with 35" 's and program the ratio and tire size using the Edge programmer. Sombody knows if the ABS have to be programmed for the 35" tires?

The programmer should take care of it. Im not sure how good the Edge is, but i didn't have any problems with 4.88s and 35s using the predator.

 

Try tweaking your tire diameter in .25" increments, either larger or smaller.

 

Edit: i did have to tweak mine... once you get the right tire size dialed in you should be good to go.

As a matter of fact, I did...but not immediately. I drove it for a day or so, before I reprogrammed, but the truck had been previously programmed for my old 305/55's.

It's b/c of the 4.88 gears. I haven't reprogrammed mine yet and no lights at all.
