Check that ground for the abs mine did that accept they would flash on and off. The gound will be on the passenger side right by the fender.

i just swapped wheels & tires ... i had 255/ 55/17 all 4 ..... now 295/45/18 rear with 245/40/17 front ... my basic tune involved a 373 ratio also ... a freind mentioned a relationship between those & a tune requirement .... i think my speedo gauge is off too ... i feel like driving 80 mph while speedo reads 65 mph !!
any input apreciated ...
note that this issue came on only when i fixed the cruise control clutch pedal switch .... !!

Did you do that? I had the same issue, and it was that bad ground.

i cant beleive someone didnt catch that before. You ahve two completely different size tires on your car, and they are ******* with your computer. Your brakes and grounds are fine, the PCM is seeing 2 wheels traveling at one speed and 2 traveling at the other (revolutions per mile speed). Your rear tires are 29" tall and your fronts are 25". That is a retarded difference and what is causing it. **** how the hell did you get a 295/45/18 to fit?! my 295/45/17s rub a **** ton i can only imagine if they were on 18s

post pictures. I bet you $100 that if you put 4 matching size tires on the car the speedo would be off but the abs and brake like would turn off too
