3. Operating Instructions
3.1 TPMS Sensor Programming
The TS408S supports programming of Autel MX-Sensors using two primary methods:
- Auto Create: This mode allows programming of 1 to 16 sensors simultaneously, significantly improving efficiency.
- Copy by OBD: This method reads the existing sensor ID directly from the vehicle's OBDII system and writes it to a new MX-Sensor, ensuring seamless replacement without manual ID input.

3.2 TPMS Sensor Relearn
After replacing or rotating TPMS sensors, they must be relearned to the vehicle's ECU to clear warning lights. The TS408S supports three relearn methods:
- Stationary Relearn: Requires the vehicle to be in a stationary position.
- Automatic Relearn: Sensors are relearned by driving the vehicle.
- OBD Relearn: Sensor IDs are transferred directly to the vehicle's ECU via the OBDII port. This is often the fastest and most reliable method.
The tool provides guided, step-by-step procedures for over 1000 vehicle models, making the relearn process straightforward.

3.3 TPMS Sensor Activation
The TS408S can wirelessly activate 99% of OEM and aftermarket TPMS sensors (315MHz and 433MHz). To activate a sensor:
- Select the correct vehicle make, model, and year on the tool.
- Place the TS408S near the tire valve stem (within 1 inch of the antenna).
- Press the activation button on the tool.
- Repeat for each sensor.
Upon successful activation, the tool displays detailed sensor data including ID, pressure, temperature, battery status, position, and frequency.

3.4 TPMS Diagnosis and DTCs
The TS408S connects to the vehicle's OBDII system to perform a complete TPMS health check. It can read and clear TPMS Diagnostic Trouble Codes (DTCs) with clear descriptions, helping to identify issues such as low tire pressure, faulty control modules, or unidentified sensors.
