Innova SD35 SD-Advisor: Tire Pressure Monitoring System Relearn

Purpose

To guide users on how to perform the TPMS relearn while using the Innova SD35 SD-Advisor Tablet Scan Tool.

Introduction

Tire Pressure Relearning is a crucial maintenance procedure that is required for vehicles equipped with a Tire Pressure Monitoring System (TPMS). The TPMS module of a vehicle registers or relearns the unique ID of each wheel's TPMS sensor and its associated wheel. This relearning process is necessary whenever a sensor is replaced or when changing the tire position, ensuring that the new sensor ID or the new sensor ID for that specific wheel location is properly registered in the vehicle's TPMS module. Several methods to perform a tire pressure relearn are used depending on the vehicle make and model and the type of TPMS system installed.

The Innova SD35 SD-Advisor Tablet Scan Tool lets you access this procedure. Use this to initialize/ relearn the Tire Pressure Monitoring System, or TPMS, and turn off a TPMS light/ message on the

dashboard. Also, use this function to write the ID of the new sensor to the control module whenever the TPMS sensor is replaced.
