The codes it throws is C1115 (Wheel speed sensor input fault) with is really generic and just tells me that the ABS module just doesn't see wheel speed signals it expects to see and shuts ABS off. I honestly think it's something in the software and there's nothing physically wrong with the car. I've inspected my speed sensors to make sure they weren't dirty or had a lot of metal attached to them, which they don't. I'm wondering if my Z1 diff cover has anything to do with it, but the sensors seem to have a good air gap from the reluctor wheels, and also I think I had the same issue while I had the stock cover on, as well, but I could be wrong.

I had something similar on a wet track day that I'm still trying to figure out.
ABS was freaking out going into corners and all my dash lights lit up for a second or so.
They'd then turn off, and also set traction control back on (traction control went from turned off, to default).
I then turned TC back off coming out of the corner and the same happened twice more.
On the third corner, the whole car shut off and wouldn't start back up again.
I've been thinking it's battery or alternator related and haven't tested yet, but seeing this thread, I'm wondering if it could've been related to confusing the ABS.
