A TPMS Relearn program configures the tire pressure monitoring functionality on vehicles with a Tire Pressure Monitoring System (TPMS). Whenever a TPMS component is installed or serviced, a TPMS Relearn needs to take place. Types of service include replacing vehicle tires, rotating vehicle tires, changing the air pressure in vehicle tires, or replacing a tire pressure sensor for any tire on a vehicle. Running the TPMS Relearn program ensures proper calibration of the TPMS sensor.
TPMS Relearn requirements vary by the year, make and model of a vehicle. Likewise, car owners must refer to the TPMS Relearn instructions in your vehicle owner's manual.
For vehicles with a factory-installed TPMS, the TPMS relearn program may automatically run after service to the vehicle's TPMS. If this does not occur, or if you are using aftermarket TPMS components, you may need to complete the TPMS Relearn programming yourself using TPMS diagnostic tools.
Regardless of the required steps, the goal of the TPMS Relearn procedure is to accurately register or recalibrate the tire sensors on a vehicle. After all required TPMS Relearn programming steps are complete, typically you'll need to drive the vehicle for 10-15 minutes to confirm if the tires have the correct and safe amount of air pressure.
