But yeah, get that code first if you can.
When I was running a steel wheel I had because of a bent rim the tire size was off on that wheel. The ABS and trac light would kick when I hit 60mph.

To the OP, just because the PO replaced the hub doesn't mean he replaced the right part. I once had an issue with the light randomly kicking and I found a broken wire in the passenger front harness.
