Preferred Scan Tool Learn Mode

  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 left front tire, follow either of these 2 procedures:
    • Increase/Decrease Method:  Increase or decrease tire pressure for 8-10 seconds, then wait for the horn to make a chirp sound. The horn chirp may occur before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached
    • Sensor Activation Tool Method:  Starting with the left front tire, hold the activation tool against the tire wall aiming upward with the antenna. Press the activate button and wait for a horn chirp.
  3. After horn chirp has sounded, repeat procedure for the next 3 sensors in the following order: right front, right rear and 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.
