5. Operating Instructions
5.1 Activating TPMS Sensors
The i-TPMS TSGUN can activate both 315MHz and 433MHz OEM and universal TPMS sensors. This process wakes up the sensor and allows the tool to read its data.
- Ensure the i-TPMS TSGUN is powered on and connected to your X431 scanner or i-TPMS app.
- Select the "Activate" function from the menu.
- Hold the i-TPMS TSGUN near the tire valve stem of the sensor you wish to activate.
- Press the "OK" button on the device. The tool will emit a signal to activate the sensor.
- Once activated, the sensor data (ID, pressure, temperature, battery status) will be displayed on the screen.

5.2 Reading Sensor Status
After activation, the i-TPMS TSGUN can display real-time data from the TPMS sensors, including:
- Sensor ID
- Tire Pressure (kPa/PSI/Bar)
- Tire Temperature (°C/°F)
- Battery Status
- Sensor Position
- Sensor Frequency

5.3 Relearning TPMS Sensors
After replacing a TPMS sensor or performing tire service, the new sensor IDs must be relearned to the vehicle's ECU. The i-TPMS TSGUN supports three relearn methods:
- OBD Relearn: Connect the X431 scanner (or i-TPMS app with OBD dongle, if supported) to the vehicle's OBD-II port. Follow the on-screen instructions to transfer new sensor IDs to the vehicle's computer.
- Automatic Relearn: For vehicles that support automatic relearn, drive the vehicle for a specified period (e.g., 10-20 minutes) at a certain speed (e.g., above 25 mph) after sensor replacement. The vehicle's ECU will automatically learn the new sensor IDs.
- Stationary Relearn: Some vehicles require a stationary relearn procedure, often involving specific steps like inflating/deflating tires in a particular sequence. The i-TPMS TSGUN, when connected to an X431 scanner, provides guided instructions for these procedures.

5.4 Programming TPMS Sensors
The i-TPMS TSGUN exclusively supports programming of LAUNCH LTR RF sensors. It can program these sensors an unlimited number of times, offering a cost-effective alternative to expensive OE sensors. Four programming methods are available:
- Auto Create: The tool generates a new, unique sensor ID.
- Manual Create: Allows you to manually input a desired sensor ID.
- Copy by Activation: Reads the ID from an existing sensor and copies it to a new LAUNCH sensor.
- Copy by OBD: Retrieves sensor IDs from the vehicle's ECU via the OBD-II port and copies them to new LAUNCH sensors.
Note: This tool does not program OEM sensors; it is designed for LAUNCH LTR RF sensors only.

6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the device regularly, even if not in use for extended periods.
- Firmware Updates: Periodically check for firmware updates through the LAUNCH X431 scanner or the i-TPMS app to ensure optimal performance and compatibility with new sensors and vehicles.
7. Troubleshooting
