: Service Tire Monitor System.. Just turned on

05-25-12, 11:35 AM
I was driving to work its 85 degrees out and all the sudden my Dash tells me "Service tire monitor system" so i check the tire pressures thinking maybe one ios down and the left rear tire is showing --.

Anyone know what can cause this the tires are all fine i even manually checked the pressure.

Some times the batteries go, they only last usually 4-6 years, and some times they just get confused

Hello PeteKT,

It looks as though you're well within the Bumper to Bumper warranty by mileage; we can check with the last 8 digits of your vehicle's VIN to see if you're still within the mileage by date (4 years from the in-service date of the vehicle). Generally speaking, the Bumper to Bumper warranty covers against defects in materials or workmanship for most vehicle components (maintenance items excluded), but a dealership diagnosis helps us to determine if a vehicle concern was caused by an environmental factor, etc.

Again, we can check into the expiration date of your Bumper to Bumper warranty if you were to send us the last 8 of your VIN.

I would try and relearn the sensors per your owners manual and see if that corrects the problem. You pick relearn from the dic and go to each tire and let pressure out until the truck honks at you and then move on to the next tire and repeat. You start at the left front then rf, rr, lr and then It honks twice I think. Try this before you take it some where.
Once set, adjust the tire pressures and your golden. I hope.
