The i-TPMS can activate and read supported OE and aftermarket 315 / 433 MHz TPMS sensors.

Writing new sensor data is intended for compatible LAUNCH programmable universal TPMS sensors. Most original OE sensors are factory-coded and are not themselves rewritable universal sensors.

OE sensor support does not mean that the i-TPMS can rewrite every original sensor.

Original sensors can normally be activated, identified, tested and relearned where supported. For creating or cloning a replacement sensor, use a compatible programmable LAUNCH universal TPMS sensor.

Coverage depends on the exact manufacturer, model, production year, market and TPMS architecture.

LAUNCH specifies approximately 98–99%+ mainstream TPMS coverage, but functions may differ between individual vehicles.

TPMS functions depend on the vehicle’s TPMS architecture, model year, market and operating mode.

Full relearning and TPMS ECU diagnosis require a compatible LAUNCH diagnostic tool. Standalone Android operation provides a reduced function set.

LAUNCH programmable TPMS sensors are sold separately unless a sensor bundle is specifically stated in the selected product configuration.

A compatible LAUNCH X431 scanner and its VCI are required for full TPMS diagnosis and OBD relearning. The i-TPMS can alternatively perform supported standalone functions through the Android i-TPMS app.
