1. Introduction
The VEHLIVE SU-50448 is a compact and efficient tool designed for activating and resetting Tire Pressure Monitoring System (TPMS) sensors in most GM vehicles. This tool is essential after tire rotation, sensor replacement, or seasonal tire changes to ensure accurate tire pressure readings and clear dashboard warnings. It operates on both 315 MHz and 433 MHz frequencies, making it compatible with a wide range of GM models.

3. Operating Instructions
3.1 Preparing Your Vehicle for TPMS Relearn
Before using the tool, your vehicle must be placed into TPMS learning mode. The exact procedure varies by vehicle model. Typically, this involves navigating through your vehicle's dashboard menu using steering wheel controls.

3.2 TPMS Relearn Procedure
Once your vehicle is in TPMS learning mode, follow these steps to activate and relearn each tire sensor:
- Start with the left front tire.
- Position the VEHLIVE SU-50448 tool's antenna against the tire sidewall, directly next to the valve stem.
- Press the 'Learn' button on the tool. Hold it stationary against the tire sidewall.
- Wait for the vehicle's horn to beep once. This indicates that the sensor for that tire has been successfully activated. The green LED on the tool will also indicate transmission.
- Proceed to the next tires in the following order: right front, right rear, and finally left rear. Repeat steps 2-4 for each tire.
- After all four sensors are reset, the vehicle's horn will sound twice, confirming that the TPMS relearn process is complete.

4. Maintenance
To ensure the longevity and optimal performance of your VEHLIVE SU-50448 TPMS Relearn Tool, follow these maintenance guidelines:
- Keep the tool clean and dry. Wipe it with a soft, damp cloth if necessary. Avoid using harsh chemicals or abrasive cleaners.
- Store the tool in a safe place away from extreme temperatures, direct sunlight, and high humidity.
- Ensure the battery compartment is always closed to prevent dust and moisture from entering the device.
- Remove the 9V battery if the tool will not be used for an extended period to prevent battery leakage.
5. Troubleshooting
5.1 Common Issues and Solutions
- Tool does not activate a sensor (no horn beep):
- Ensure the tool is held correctly against the tire sidewall, directly next to the valve stem. Refer to the 'Correct Position of Antenna' image in Section 3.2.
- Verify that the vehicle is properly in TPMS learning mode.
- Check the tool's 9V battery. Replace it if it is low or depleted.
- Ensure you are following the correct tire activation sequence (Left Front, Right Front, Right Rear, Left Rear).
- TPMS warning light remains on after relearn:
- Confirm all four sensors were successfully activated (vehicle horn beeped for each).
- Drive the vehicle for a few minutes (e.g., above 20 mph for 10-15 minutes) to allow the system to fully update.
- If the issue persists, there might be a faulty TPMS sensor or another underlying issue with the vehicle's TPMS system. Consult a professional mechanic.
