4. Setup
4.1 Battery Installation
The VXSCAN OEC-T5 tool requires a new 9V battery for operation. The battery is not included with the device.
- Locate the battery compartment on the rear of the tool (refer to Image 2.1).
- Open the battery compartment cover.
- Insert a new 9V battery, ensuring correct polarity.
- Close the battery compartment cover securely.
If the LOWBAT LED illuminates during use, replace the battery with a new 9V battery to ensure optimal performance.
5. Operating Instructions: TPMS Relearn Procedure
The TPMS relearn procedure is typically required after tire rotation, sensor replacement, or when the tire pressure alarm is active. Follow these steps to activate and match your TPMS sensors:

5.1 Three-Step Relearn Process
- Enter Learning Mode:
Ensure your vehicle is in the TPMS "learning mode." The method to enter this mode varies by vehicle model. Typically, this involves navigating through the vehicle's infotainment or driver information center menu. Consult your vehicle's owner's manual for specific instructions. Once in learning mode, the vehicle's horn may sound twice, or a message like "Tire pressure learning mode" will display.
- Read Tire Pressure Sensor Information (Left Front Wheel):
Starting with the left front wheel, position the VXSCAN OEC-T5 tool close to the tire valve stem, against the sidewall of the tire. Press and hold the Operating Key on the tool. The tool's TX LED will illuminate, indicating it is transmitting. Hold the tool in place until the vehicle's horn sounds once, confirming the sensor has been read.
- Read Remaining Sensors (Clockwise):
Proceed to the other three tires in a clockwise direction:
- Right Front Wheel
- Right Rear Wheel
- Left Rear Wheel
Repeat the process from Step 2 for each wheel. After the final tire's sensor is successfully read, the vehicle's horn will sound twice, indicating the completion of the relearn procedure.

5.2 Correct Tool Positioning
For optimal signal transmission and successful sensor activation, hold the tool close to the tire valve stem. The ideal position is typically 90 degrees or 180 degrees relative to the valve stem, pressed against the tire sidewall. Avoid holding the tool too far away or at an incorrect angle, as this may prevent the sensor from activating.

6. Maintenance
- Battery Replacement: Replace the 9V battery when the LOWBAT indicator illuminates to ensure consistent performance.
- Cleaning: Wipe the tool with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the tool in a dry, cool place away from direct sunlight and extreme temperatures.
- Avoid Moisture: Do not expose the tool to water or excessive moisture.
7. Troubleshooting
