Default traction control/ABS

2004 supercharged SS. i put new CV shafts,
Front rotors and brakes on. now have traction control and abs lights on. pulled the quick connection at the break control module and using an ohm meter i have 1.067 RF and 1.109 LF. sensors are good? i disconnected the battery to reset system. no joy. any help is appreciated.

Are the lights on continuously or do they come and go? If they're intermittent then you likely have a short in the ABS wiring harness somewhere. Even if they're not intermittent that could just mean a full break in the harness somewhere rather than just a short. But before that, when you say you disconnected the battery to reset the system, did you leave the battery unplugged for 15-30 minutes before reconnecting it? If not, I would start with that and if that doesn't work then I would start inspecting the harness for bare wire or a break somewhere.

Since the timing lines up exactly with the work you did around the sensors, my first step would be to jack it back up, pull the wheels off, and inspect the sensors + harnesses.

Maybe something got hit / pinched during that work?

As far as the ohm readings - are you sure that isn't k ohm? Reading about 1 ohm is nearly a dead short. I don't know what the spec is on them, but the few reluctance sensors Ive dealt with have had resistance in the hundreds of ohms - not single digits.

Check your ABS fuse as well. Could be as simple as that..... unless it starts popping regularly.
