Warning lights for ABS/Traction Control stating "have systems serviced". Brakes & rotors recently replaced. Any success?

    Lights on right after the replacement, or was everything fine and now the lights have come on? The ABS system relieves brake pressure on a wheel that it senses is nearing lock-up. The traction control system applies brake pressure if the wheel is over accelerating. So while it could be related to the brake and rotor change, it may also be the wheel speed sensors and/or modulator valve. You're probably going to need a scan tool to get a code to find out what's going on. Or at least what the computer thinks is going on
