TPMS Reminder Reset - Procedure 33

If refilling a low tire, no specific reset procedure is required. All warnings are extinguished once the TPMS receives a signal that all tires are properly inflated.

Each TPMS sensor has a unique identification code. The identification code needs to be matched to a new tire/wheel position after rotating the tires or replacing one or more of the TPMS sensors. The TPMS sensor matching process should also be performed after replacing a spare tire with a road tire containing the TPMS sensor. The malfunction light and the DIC message should go off at the next ignition cycle. The sensors are matched to the tire/ wheel positions, using a TPMS relearn tool.

  1. Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
  2. Set the parking brake.
  3. Turn the ignition to ON/RUN with the engine OFF.
  4. Press the MENU button (center console) to select the Vehicle Information Menu in the Driver Information Center (DIC).
  5. Use the arrow keys to scroll to the Tire Pressure screen.
  6. Press the SET/CLR button to begin the sensor matching process. A message should display requesting acceptance of the process.
  7. Press the SET/CLR button again to confirm the selection. The horn sounds twice to signal the receiver is in relearn mode and the TIRE LEARNING ACTIVE message displays on the DIC screen.
  8. Starting with left front tire, hold a tire sensor activation tool against the side wall of the tire, within 3 inches of the valve stem. Activate tool until a horn chirp sounds.
  9. After horn chirp has sounded, proceed to the next 3 sensors in the following order: right front, right rear and left rear.
  10. After left rear sensor has been learned, a double horn chirp will sound, indicating all 4 sensor IDs have been learned. Turn ignition switch to OFF position to exit Learn Mode.
