I have a 2006 silverado with a 5.3. i changed the gears to 4.56 and put 35 inch tires on it. In the start the rear abs sensor was reading faster then the front.
I went in with my snap on verus and changed the abs tire size to 31/10.5 in the abs module and used hptuners to change the tire and gear size in the pcm. with both at 31 the rear still reads faster. I then modified the hptuner tire size until the abs sensors read the same mph when driving. Now i have no abs light or code c0245 anymore just my abs activates when i am almost stopped at almost every stop. It was safer to drive with the abs light coming on because once the abs light came on the abs was deactivated. Is there a way to fix it to work like factory again or am i doomed to have some sort of issue with it because of the tire and gear change?
