4. Instruccions de funcionament

The LAUNCH X-431 i-TPMS offers two modes of operation: binding with a compatible LAUNCH X-431 scanner or operating standalone with the i-TPMS mobile application.

4.1 Operation with LAUNCH X-431 Scanner

When bound with a LAUNCH X-431 scanner (8-inch screen or above), the i-TPMS can perform a full range of TPMS services including activation, programming, relearn, and diagnosis for sensors.

Figura 4.1: Mésview of TPMS functions available with an X-431 scanner.

Activació: Read sensor ID, tire pressure, tire temperature, sensor battery, sensor position, and frequency.
Programació: Create new sensor IDs for LAUNCH sensors. Supports auto-creation for 1-16 sensors or manual input.
Torna a aprendre: Perform Stationary Relearn, Automatic Relearn, or OBD Relearning procedures to link new sensor IDs to the vehicle's ECU.
Diagnòstic: Read and clear TPMS fault codes.

4.2 Standalone Operation with i-TPMS Mobile App

The i-TPMS can also function independently when paired with the i-TPMS mobile application on an Android phone. This mode supports sensor activation and programming.

Replace Tire Pressure Sensor: Guide through the process of replacing a sensor.
Activa el sensor: Initiate communication with the sensor to read its data.
Program Sensor ID: Create new sensor IDs.
Query Sensor OE Part Number: Retrieve original equipment part numbers for sensors.
Generate Tire Pressure Detection Reports: Create reports based on sensor data.

4.3 Programació del sensor TPMS

The i-TPMS allows for programming LAUNCH LTR RF sensors to replace original equipment (OE) sensors. This process can be done automatically or manually.

Figure 4.2: Sensor ID programming options.

Auto Create Sensor ID: If the original sensor ID is unknown, the i-TPMS can automatically generate a new ID.
Manual Create Sensor ID: Allows the user to manually input a specific sensor ID.

4.4 TPMS Relearn Procedures

After replacing or programming a sensor, a relearn procedure is necessary to ensure the vehicle's ECU recognizes the new sensor IDs.

OBD Relearn: Connects to the vehicle's OBD-II port to transfer sensor IDs.
Automatic Relearn: Sensors are automatically learned by driving the vehicle.
Reaprenentatge estacionari: Requires specific steps to be performed while the vehicle is stationary.

4.5 Lectura i esborrat de codis d'error

The i-TPMS can diagnose issues within the TPMS by reading and clearing diagnostic trouble codes (DTCs).
