I started to have the very same issue with the TCS/ABS/Slip Light right after I replaced the rear/passenger hub bearing due to noise. I though I had a defective new part, replaced it with the old one and the lights persisted. I wonder If I damaged the sensor for that wheel? Any tips appreciated.
PS. 04 quest. It may be worth noting I had also replaced the cam sensor close to the firewall about a week prior.
