It's gotta be a cmos level GPIO input to some chip... going low (or high..whatever), the display controller toggles power to the warning light.. That seems like the easiest fix where-- in reality, its going off, but the driver simply doesn't see it flashing..

You'd be many TPMS sensorless drivers' hero if you figured out how to do that without voiding the warranty on the car and posted instructions on the forum :D . Sounds like you're a digital engineer?
