The repair shop rotated my tires and did not relearn them. I tried to do it myself. Once I get to the 3rd tire which is rear passenger, it beeps twice and I couldn't get the rears to learn. I drove 5 miles the front reset on its own and no longer display any number. Also read "service pressure monitoring system" . I tried again...I can only get to tire learning active(beep twice)...tires won't beep again for me, pressure drop to 15psi still wont beep. Please help...
