????'s on ABS

If I didn't have rear ABS breaks on my car, and just had the front...what would happen?

Considering that the ABS system looks for input from the rear sensor as well as the front wheels, leaving the rear unplugged doesn't mean you simply don't have rear ABS. You will probably have the ABS INOP light come on, and the ABS system won't function.

I think you'd also throw and SES, because the PCM also looks for the signal from the reluctor ring, which comes through the ABS sensor. I know when I dyno the car, the PCM goes ape and throws a code because the rear wheels are showing 100+mph and the fronts aren't moving. It'd probably be the same thing with the rear disconnected.
