I have searched various terms (lowered + VDC, ABS, slip, "warning light": unless I wasn't clued in well enough by the thread title, I haven't found this same issue)...I can't be the first person this has happened to, so maybe I am not using the right search query?

I have found these that are close, but not exactly what my issue is:

My Z is a 2004.5 Performance. Bought the SPCs and Tokicos from THMotosports about a month ago. Front and rear camber arms installed this weekend, along with new shocks (I am lowered on Sportlines).

Immediately after driving the car with the new equipment installed, the VDC, brake and slip light popped on--all at once. I have already tried reseting everything (both battery disconnect and accelerator pedal method). When I turn my car back on, for a moment everything is fine; but as soon as I drive a few yards, my dash lights up like a Christmas tree. My pads look great (~25K easy miles on the car), and I topped off the brake fluid (which was above in the first place). Fuses all look fine, too.

Now besides the slight alignment issue, the car is driving normal. Granted I haven't carved any tight corners at 90mph, but drove it enough to check for odd noises, etc...I was thinking that it would possibly reset itself, but I drove about 30 miles on a round-trip jaunt to an Auto Parts store and all the lights are still on. I went to the auto parts store so they could pull the code(s) that were being thrown; the guy said it had something to do with the front passenger ABS, muttered something else, then went inside never to be seen again. Oooooookayyyyyy...thank you for nothing.

My only guess is that I compressed the brake caliper when putting everything back in and it has something to do with the piston being reset. I haven't read about any issues with the camber arms, but could this be a problem with spacing the rotor&caliper out to fit the SPCs? Possible problem with the speed sensor? Should I just try reseating the pads? Any other ideas? I'm at a loss.

 

My guess would be that you damaged one of the wheel speed sensors and/or the connecting cable.

 

I suppose, but it seems like to me that if I did damage it, my ABS would go in to limp mode. No?

 

when all else fails, read the instructions

so, at the bottom of one of the sheets it mentions that a code will be thrown if the ABS sensor is not aligning perfectly with the hub, and should have a gap within ".37mm and .41mm"...tight parameters! Doesn't help that the bracket seems pretty breakable...regardless, this sounds likely. I will check this first when I get an alignment done. Has no one else ran in to this problem before?
