MAKE TPMS SENSORS OPERATIONAL AT PDI

SERVICE NEWS

SERVICE INFORMATION

When you're doing a PDI, remember to make all of the TPMS sensors operational. If you forget to do this, the TPMS indicator will come on after about 20 miles of driving. If that happens to a new vehicle owner, your service department is sure to get a visit from one very unhappy customer. When the TPMS indicator comes on, the TPMS control unit also sets one or more TPMS DTCs, depending on the situation. Clearing those DTCs at PDI or shortly after isn't a warrantable repair.

For '08, we've made it easier to make those TPMS sensors operational. Here's how to do it:

1. Turn the ignition switch to LOCK (0).
2. Use a tire pressure gauge with a bleeder valve to quickly drop the pressure in one tire to 18 psi or less  .
IMPORTANT: You must drop the tire pressure by 3 psi  within 15 seconds  , or the TPMS sensor won't turn on. To ensure good accuracy, use the calibration tool (P/N 07AAJ-000A100, H/C 8298457) to periodically check your tire pressure gauge. This tool was sent to your dealership last August.
3. Inflate that tire to the recommended cold inflation pressure that's listed on the driver's doorjamb sticker. If you're in a cold climate region, make sure the tire is at the same temperature as the outside air before you inflate it; otherwise, the low tire pressure indicator may come on when the weather gets cold.
4. Repeat steps 2 and 3 for the other three tires.
   NOTE: Since the spare doesn't have a TPMS sensor, there's nothing you need to do. Just make sure it's inflated to the recommended cold inflation pressure.

One final note: If you're installing accessory wheels, make sure you follow the accessory installation instructions to the letter. This will ensure trouble-free TPMS operation.
