No, the indicator wasn't on. The rotors needed changing, so I changed the pads as well. So it sounds like the light shouldn't trip unless the sensor is physically damaged, a wire is cut, or there's a bad connection? Again, disconnecting the sensor and checking for continuity should give me an answer, right? I'll try resetting the light as suggested...
