Problem: ABS + traction control lights come on and stay on. Started after an autocross day on my drive home.

Fix Attempts:
1. Checked brake fluid level, lights came back.
2. Filled brake fluid level flush with full line, lights came back.
3. Inspected sensor wiring at wheels, nothing obviously wrong.
4. ECU scan, no codes.
