This multipurpose TPMS tool offers five key functions for tire pressure monitoring system service. 1. TPMS Relearn: Compatible with almost all known sensor IDs. Perform an automatic relearn when rotating tires, or a stationary relearn to introduce new sensor IDs into the vehicle's electronic control unit. 2. Sensor Programming: Three easy methods – activate a copy, manually enter, or auto-create up to 16 sensors. Program many sensors in seconds. 3. Sensor Activation: Triggers the majority of TPMS sensors on the market. Quickly and accurately trigger and decode sensors to read ID, pressure, temperature, and voltage before servicing or during programming/relearning. 4. Sensor Reading: Retrieve sensor ID, pressure, temperature, and battery condition for real-time tire status. Based on details like manufacturer, frequency, and relearn type, easily identify the needed sensor. 5. Multifunction: Supports tire pressure system fault diagnosis, read/clear codes, view data flow. Includes special functions: ECU calibration, delete NTP signal, write wheel group, set tire pressure alarm value, reset/initialize, write VIN code, and run automatic balancing.
