3. Setup

Before using your Autel MaxiTPMS TS408S, ensure it is properly set up and charged.

3.1 Initial Charging

The device is powered by a 3.7V Li-polymer battery. Connect the included USB cable to the device and a power source (e.g., computer USB port or a USB wall adapter) to charge the unit. A full charge is recommended before first use.

3.2 Powering On/Off

• To power on: Press and hold the power button (usually marked with a red circle and line) until the screen illuminates.
• To power off: Press and hold the power button until a shutdown prompt appears, then confirm.

3.3 Language and System Settings

Navigate through the device menu using the directional buttons and 'OK' button. Access the 'Settings' menu to configure language (19 languages supported), display brightness, and other system preferences.

4. Operating Instructions

This section details the primary functions of the Autel MaxiTPMS TS408S.

4.1 Sensor Activation

Sensor activation is the process of waking up a TPMS sensor and reading its data. This is a crucial first step before programming or relearning.

1. Select the 'Activate Sensors' option from the main menu.
2. Hold the TS408S tool close to the tire valve stem of the sensor you wish to activate.
3. Press the trigger button on the device.
4. The device will receive and display sensor data, including sensor ID, tire pressure, temperature, and battery status.

4.2 MX-Sensor Programming

The TS408S can program Autel MX-Sensors to replace faulty or new sensors. There are several programming methods:

• Copy by OBD: Connect the TS408S to the vehicle's OBDII port using the included cable. The tool will retrieve the old sensor ID from the vehicle's ECU and write it directly to the new MX-Sensor. This method is ideal for direct replacement without relearning.
• Copy by Activation: Activate the old sensor to retrieve its ID, then write this ID to a new MX-Sensor. This allows the new sensor to be installed in the original position without requiring a relearn.
• Copy by Manual Input: If the old sensor is completely damaged or its ID cannot be read, manually input the old sensor ID (found on the sensor housing) into the TS408S, then program it to the new MX-Sensor.
• Auto Create (1-16 Sensors): If no old sensor ID is available, the TS408S can automatically generate new random IDs for MX-Sensors. A relearn procedure will be necessary after using this method.

4.3 Sensor Relearn Procedures

After replacing or programming TPMS sensors, a relearn procedure is necessary to allow the vehicle's ECU to recognize the new sensor IDs. The TS408S supports multiple relearn types:

• Automatic Relearn: For vehicles that can automatically learn new sensor IDs by driving for a certain period at varying speeds. The TS408S can guide you through this process.
• Stationary Relearn: This procedure requires placing the vehicle into "learn mode" (often through specific vehicle actions or using the TS408S) and then activating each sensor to transmit its ID to the vehicle's ECU without driving.
• Relearn via OBD: Connect the TS408S to the vehicle's OBDII port. The tool can directly write the new sensor IDs to the vehicle's TPMS module, simplifying the relearn process.

The TS408S provides on-screen relearn guides for over 1000 vehicles, offering step-by-step instructions for the exact process required for your specific vehicle model.

4.4 TPMS Health Check & Data Reading

The TS408S allows for quick and comprehensive assessment of your TPMS system's health.

• Read Sensor Information: After activation, view detailed sensor data including sensor ID, current tire pressure, tire temperature, sensor battery status, sensor position, and frequency. This data helps identify issues like low battery or incorrect pressure.
• Read/Erase TPMS DTCs: Access and clear diagnostic trouble codes related to the TPMS system.
• Display TPMS Live Data: Monitor real-time TPMS data, often presented in graphical form for easy analysis.
• Access TPMS ECU Information: Retrieve information directly from the vehicle's TPMS Electronic Control Unit.
• Turn Off TPMS Malfunction Light: After resolving TPMS issues, use the tool to turn off the warning light on the dashboard.
