| Have you changed the trucks batteries. After 2 years I had to replace bout batteries on my duramax. Light came on. Took to dealer. Had tire pressure computer reading re installed. Hope this makes sense. Or if you know anyone that has tech 2 or newer it's very simple. If it's important to you to know the pressures tell them to simply turn off feature. Cold morning and hot afternoons make mine go on and off. They're very finicky. My buddy did this, next time he put new tires on his truck be removed all sensors from rims and threw them inside spare and aired to correct pressure lol. | |
