Preferred Scan Tool Method

  1. Using a scan tool, initiate the TPM Learn Mode. A double horn chirp will sound indicating the Learn Mode has been enabled. The left front turn signal will also be illuminated.
    IMPORTANT:

    In the event a particular sensor's information is displayed on the special tool upon activation but the horn does not chirp, it may be necessary to rotate the wheel valve stem to a different position due to the sensor signal is being blocked by another component.

  2. Starting with the left front tire, active the sensor by holding the antenna of the Sensor Activation Tool aimed upward against the tire sidewall close to the wheel rim at the valve stem location. Press and release the Activate button and wait for a horn chirp. Once the horn chirp has sounded, the sensor information is learned and the turn signal in the next location to be learned will illuminate.
  3. After the horn chirp has sounded and the right front turn signal is illuminated, repeat procedure for the remaining 3 sensors in the following order: Right front, Right rear, Left rear.
  4. When the left rear sensor has been learned and a double horn chirp has sounded, the learn process is complete and the RCDLR exits the learn mode.
  5. Turn ignition OFF, adjust all tires to the recommended pressures.
