  Q: How to Service and Repair the TPMS Sensor on Lincoln MKT?

  A: A first step before servicing or repairing the Tire Pressure Monitoring System (TPMS) is to wake up sensors if the vehicle stays stationary for longer than thirty minutes because sensors automatically enter "sleep mode" to save battery power. Perform sensor training procedures exclusively on one vehicle which must operate in a radio frequency noise-free zone while staying more than one meter separate from other vehicles equipped with TPMS. The Tire Pressure Monitor Activation Tool needs a second activation attempt when the wheels receive at least one-fourth of rotation. A Smart Junction Box (SJB) needs two minutes to identify tire pressure sensors before it will begin sounding the horn two times at the same time as emitting the "TIRE NOT TRAINED REPEAT" warning message. This requires restarting the training process. The TPMS indicator can be prevented from turning on by training sensors immediately after conducting a tire rotation on vehicles that utilize different tire pressures between the front and rear sections. Begin the training by shutting off the ignition then pressing the brake pedal once before running the ignition to the RUN state three times and then pressing the brake pedal once more before turning off the ignition. Successful entry into training mode can be confirmed through indicator flashing along with a horn sound after performing the ignition cycle three times. Press the test button on the Tire Pressure Monitor Activation Tool that should be placed at the valve stem to activate the LF tire pressure sensor. This action will generate a short horn sound. Press the test button on the Tire Pressure Monitor Activation Tool at each tire stem one after the other but keep each sensor in sequence no longer than 2 minutes. The training completion notification appears as "TIRE TRAINING COMPLETE" in the display or occurs after turning off the ignition without horn activation. A failed training process will result in two horn sounds when trying to shut off the ignition. A scan tool should be used to find and record the new TPMS sensor identifiers which trained to the SJB on the warranty claim, also conducting an SJB On-Demand Self Test when installing a new SJDB to verify no additional issues exist.
