TPMS Reminder Reset - Procedure 06

NOTE: If the wheels have been rotated, or tire pressure sensor or Remote Control Door Lock Receiver (RCDLR) is replaced, the TPM system needs to relearn tire pressure sensor IDs.
NOTE: When the tire pressure warning light illuminates and warning message appears on DIC, immediately check air pressure of all tires and adjust to the specified pressure. If warning indicators are still on, there is a problem in the TPM system. See appropriate manufacturer service information.
NOTE: The TPM system will cancel Learn Mode if ignition is turned off, if more than 1 or 2 minutes has passed and no sensors have been learned, vehicle battery voltage is less than 8 volts, all 4 sensors have been learned, or if the RCDLR has been in Learn Mode for more than 5 minutes. If Learn Mode is cancelled before any IDs are learned, the RCDLR will remember all previously stored IDs and their locations. As soon as the first sensor ID is learned, all other IDs are erased from the RCDLR's memory.
  1. Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
  2. Turn ignition ON with engine OFF.
  3. Press RESET button on DIC in order to clear any warning messages.
  4. Press and release OPTIONS button until display is blank.
  5. Press and hold RESET button for 3 seconds.
    NOTE: If the DIC does not display "TIRE TRAINING" message, ensure TPM option is enabled in the RCDLR. See appropriate manufacturer service information.
  6. Press and release OPTIONS button until "TIRE TRAINING" is displayed.
  7. Press and release RESET button. The DIC should display "LEARN L FRONT TIRE", verifying Learn Mode has been enabled.
  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 the horn chirp sounds, proceed to the next 3 sensors in the following order: right front, right rear, then left rear.
  10. Turn the ignition switch to OFF position to exit the learn mode.
