anti lock light?
Okay so i have a 94 mustang gt and, i just got some new wheels. 18/10 in the rear and 17/9 in the front. BEFORE i had 17/9 all the way around the car. When i got my new wheels the "anti lock" light came on. I believe this isbecause the are staggered now but could anybody tell my why this light came on. Also can you tell me what i can do to fix it and is doing nothing to this light going to hurt anything on my car?
Before new wheels 4 17/9s.
With new wheels 2 18/10s and 2 17/9s
Before new wheels 4 17/9s.
With new wheels 2 18/10s and 2 17/9s

RE: anti lock light?
Chances are that the diameter of the tire/wheel combination isnt the same in the front and rear. This will cause the sensors to read different speed values and cause the ABS fault code. Im not sure how Ford sets there ABS systems up but you may be able to cut the sensor wires at each sensor. There will probobly be 2 wires. Connect the 2 wires together to try and trick the computer into thinking you are always going zero mph. Of course you wont have ABS by doing this but chances are the system disables itself when the ABS light fault is triggered anyway, so your not going to lose anything.

heh.... yea, Ive never tried anything like that but I ment to do it to all 4 wheels. Sorry Im not to clear. Your probobly right about the other code thing but you can avoid that by leaving the sensors attatched but away from the reluctor. As for the VSS Im not sure what info the ABS module uses for its stratagy. Im a GM tech so I only have that kinda info for GM's. Chances are your right, but Id give it a try to be sure.

okay so it sounds stupid but i went to discount and got some 255/40/17s for the front and it no longer trips the light. i had 245/45/17s before this and it would trip. It doesnt do this now so would this have been enough to trip the sensors. 10mm?

as long as the rotational distance is similair compared to the rear it'll work and yes the difference previously was probably enough..it's hard to tell the exact mph diff on the front vs the rear..you'd have to of had a scan tool hooked up and hope there was a pid to read data for each wheel speed to verify it all
