thanks for all the replies, i am going to try what you guys have suggested.. i agree with 720Deere - why can't the stupid thing tell you WHICH tire is low..maybe they figured if they did that, you would just check the low one and not ALL of them...must be a method to their madness.. all i know is, this electronic computer stuff is annoying..what happened to the good old days of doing it the hard(actually - easy) way?
