4. Operating Instructions

Follow these steps to perform a TPMS relearn procedure on your GM vehicle:

1. Prepare Vehicle: Ensure your vehicle is in the TPMS relearn mode. This procedure typically involves specific steps like turning the ignition on, pressing certain buttons, or using the vehicle's infotainment system. Refer to your vehicle's owner's manual for exact instructions on entering relearn mode. The vehicle's horn may chirp twice to confirm entry into relearn mode.
2. Start with Front-Left Tire: Begin the relearn process at the front-left tire.
3. Position the Tool: Hold the VXDAS GL-50448 tool against the sidewall of the tire, near the valve stem. Ensure the antenna is in the correct position, typically at a 90-degree or 180-degree angle to the gas nozzle for optimal signal transmission.
4. Activate Sensor: Depress and hold the activation button on the tool while keeping it against the tire sidewall. The tool's TX indicator light will illuminate.
5. Confirmation: Listen for a horn chirp or observe flashing lights from the vehicle, which indicates successful activation of the sensor. Release the button once confirmation is received.
6. Proceed to Next Tires: Follow the same method for the remaining tires in the following sequence: Front-Right, Rear-Right, and then Rear-Left.
7. Complete Relearn: After activating all four sensors, the vehicle's horn may chirp twice to signal the completion of the TPMS relearn process.

5. Maintenance

Proper maintenance ensures the longevity and reliable performance of your VXDAS GL-50448 tool.

• Battery Condition: Always ensure the 9V battery is in good condition. Replace it when the LOWBAT indicator illuminates or if the tool's performance degrades.
• Cleaning: The tool features an easy-to-dismantle design for zero-pressure cleaning. Use a soft, dry cloth to wipe the exterior. Avoid using harsh chemicals or abrasive materials.
• Storage: Store the tool in a cool, dry place away from direct sunlight and extreme temperatures. Remove the battery if the tool will not be used for an extended period to prevent leakage.

6. Troubleshooting

If you encounter issues while using the VXDAS GL-50448, consider the following:

• Tool Not Activating Sensor:
  • Ensure the vehicle is correctly in TPMS relearn mode.
  • Verify the 9V battery is fresh and properly installed. The LOWBAT indicator should not be lit.
  • Confirm the tool's antenna is positioned correctly against the tire sidewall, near the valve stem, at the recommended angle (90 or 180 degrees).
  • Hold the activation button firmly and steadily.
• Vehicle Not Responding:
  • Double-check your vehicle's owner's manual for the precise steps to enter TPMS relearn mode. Some vehicles may require specific conditions (e.g., parking brake engaged, doors closed).
  • Ensure you are following the correct tire activation sequence (typically Front-Left, Front-Right, Rear-Right, Rear-Left).
• No Horn Chirp or Flashing Lights:
  • While a horn chirp or flashing lights usually confirm activation, sometimes the feedback might be subtle or delayed. Re-attempt the activation for that specific tire.
  • If the issue persists, consult your vehicle's service manual or a qualified technician.
