reset the tire pressure monitoring system, to do so, you need to get your key fob, and put your ignition key in the ignition, turn it to the accesories position, and simultaneously press the lock and unlock buttons on the key fob. hold them until the truck honks the horn.

then take something to let out air in the tires, you need to start with the left front then go to the right front, then the right rear, then the left rear.

start at the left front, drop the pressure in the tire until the horn beeps, -usually takes 8 seconds or so. then repeat on the other tires in the order i told you above.

or you can get the J tool for the TPM's and use that.

anyways, after you finish with the final tire, the horn will honk again, then you know your done. usually honks 2 times.

and then you can turn the key off, and set your tire pressures.

yes but not on the lower end ones, they dont have it available through the dic, and some of them dont even have a key fob, so you have to go to the tire relearn screen and then hold the trip reset button

you dont have to reset it if you dont want to. all resetting it will do is put the tires in there positions as to what the computer sees, it uses each of the sensors ID's to determine where they are. it wont throw a light on. but if you want to have it accurate then reset it. easy process. just takes a few to get the hang of it.


your truck should have it available through the DIC, listed under tire pressure monitor relearn. just press the check mark button when prompted and it will go from there
