There is a special tool to activate the tire pressure monitoring sensors so the controller can identify which tire is where. The special tool is actually a big magnet, such as is found in a 6x9 speaker.
Get to the point where the horn beeps twice , then hold the magnet on each tire until the horn chirps once, then move on to the next one, starting with the l/front, then r/front, then r/rear then l/rear. After ALL the sensors give a chirp, it should then beep twice after you get the chirp from yhe left rear.if any sensor doesn't chirp within 15 seconds, start over.
Hold the magnet right on the tire valve.
