2008 Silverado Brake and ABS Lights With I3

Post by Razorhawg »

Just seeing if there is a quick fix. Just purchased an I3 to tune my 2008 Silverado 1500 with the 5.3. I am running the 87 octane with the DOD delete and tire size change to 275/70/18. Speedo is off by 1mph. Ran Friday night and Saturday perfectly fine with no issues. Monday morning I had the Brake and ABS lights come on at the same time while on the interstate. Did not seem to affect anything. Once at work I turned the truck off and back on and the Brake and ABS lights were off. Any ideas what could cause this?

on 2007 and 2008 trucks, GM has a limit in the ABS module as to how big you can set the tire size to, otherwise it will trigger those lights... the fix is to set your tire height/diameter smaller until the lights stay off..
