I am having some abs codes for rear pinion factor. The dash light flash and buzz is rather annoying. After reading for several days I am still trying to figure this out. Any help would be great.
The truck has 285 70 17 terra grapplers. Its a stock 17" truck with the oem size of 245 70 17. I have read that the abs computer needs to be programmed for the larger tires size. I called several dealers who cannot confirm the necessity to do this.
It seems to me so many members here and on other forums run the larger tire sizes with no reference of having the computer programmed for this.
Am I just wasting money at the dealer? The odd thing is my scanner (aftermarket 3/400 scanner) will not delete the codes. The battery being unplugged for hours will not delete the codes. It does not go through any drive cycle before they codes appear.
I do not know how long the abs light has been on, as I bought the truck with a bad engine. I replaced it and several other parts only to be plauged by the darn abs light and the mode 1 door failure in the hvac.
