5. Operating Instructions

5.1 Device Navigation

The TS408S features a user-friendly interface with navigation buttons:

• Arrow Buttons: Navigate through menus and options.
• 'Y' Button (Yes): Confirms selections or proceeds.
• 'N' Button (No): Cancels selections or goes back.
• Power Button: Turns the device on/off.
• '?' Button (Help): Provides on-screen help and information.
• Wi-Fi/Trigger Button: Activates TPMS sensors.

5.2 Sensor Activation

To activate a TPMS sensor and read its data:

1. Select the 'TPMS' function from the main menu.
2. Choose the correct vehicle make, model, and year.
3. Position the TS408S near the tire's valve stem.
4. Press the Wi-Fi/Trigger button to activate the sensor.
5. The device will display sensor data including ID, pressure, temperature, and battery status.

5.3 Sensor Programming (for Autel MX-Sensors only)

The TS408S can program Autel MX-Sensors using two methods:

• Copy by OBD: Connect the OBDII cable to the vehicle's OBDII port. The tool will read the original sensor ID from the ECU and copy it to a new MX-Sensor. This method typically does not require a relearn procedure.
• Auto Create: If the original sensor ID is unavailable, select the vehicle make, model, and year on the device. The TS408S will generate a compatible sensor ID, which can then be programmed into a new MX-Sensor. A relearn procedure is usually required after using this method.

5.4 TPMS Relearn Procedure

After replacing or programming sensors, a relearn procedure is necessary to link the new sensor IDs to the vehicle's ECU. The TS408S supports three types of relearn procedures:

• OBDII Relearn: Connect the OBDII cable to the vehicle. The tool will guide you through writing the new sensor IDs directly to the ECU. This is the most common method for many vehicles.
• Automatic Relearn: For vehicles with automatic relearn systems, simply drive the vehicle for a specified period (e.g., 20 minutes) after sensor replacement. The vehicle's ECU will automatically detect and register the new sensors.
• Stationary Relearn: This method requires the vehicle to be stationary and often involves triggering each sensor in a specific order while the vehicle is in 'Learn Mode'. The TS408S provides over 1000 on-tool help guides for vehicle-specific instructions.

5.5 TPMS Diagnostics

To perform a TPMS diagnostic check:

1. Connect the OBDII cable to the vehicle's OBDII port.
2. Select the 'TPMS' function and then 'Diagnostics'.
3. The device will read TPMS DTCs, display live data, and provide ECU information.
4. You can clear TPMS warning lights after resolving any issues.

6. Maintenance

• Keep Clean: Regularly wipe the device with a soft, dry cloth. Avoid harsh chemicals.
• Storage: Store the device in its carrying case in a dry, cool environment within the specified storage temperature range (-10 to 45 °C / 14 to 113 °F).
• Software Updates: Perform regular software updates to ensure optimal performance and compatibility.
• Battery Care: Charge the device regularly, even if not in frequent use, to maintain battery health.

7. Troubleshooting

• Device Not Powering On: Ensure the battery is charged. Connect to the AC adapter and try again.
• Failed Software Update: Verify a stable internet connection and ensure the USB cable is securely connected. Re-download the update client and software pack if necessary.
• Sensor Not Activating/Reading: Ensure the device is positioned correctly near the valve stem. Check if the sensor is functional (e.g., not dead battery). Verify correct vehicle selection.
• Relearn Procedure Fails: Double-check vehicle-specific relearn instructions (available on-tool). Ensure all steps are followed precisely. Verify the OBDII connection if using OBDII relearn.
• Communication Error with Vehicle: Ensure the OBDII cable is securely connected to both the device and the vehicle's OBDII port. Verify the vehicle's ignition is in the correct position (e.g., ON, not just ACC).
