What's a TPMS 'relearn?'

Most people have probably never heard of a TPMS &#;relearn&#; until their auto service pro tells them they have to pay for one. A relearn refers to the process of electronically pairing a new TPMS sensor to the vehicle&#;s Tire Pressure Monitoring System. A TPMS relearn is always required when a new TPMS sensor or sensors are installed. Without pairing, or &#;relearning,&#; the sensor doesn&#;t &#;talk&#; to the Tire Pressure Monitoring System and the system simply can&#;t work.

TPMS Vehicle relearn procedures vary by automaker. Some vehicles relearn automatically when you drive them. Others require a TPMS scan tool to complete the relearn. The process for many Asian makes and models may also require connecting a tool to the OBDII connection. For each procedure the concept is the same, the car&#;s TPMS receiver learns the sensor&#;s unique ID numbers. In advanced systems the car&#;s TPMS receiver also learns the sensors&#; locations too (right front, left front, right rear, left rear, spare).
