Operating Instructions: TPMS Relearn Procedure
This procedure is used to activate individual TPMS sensors and link them to your vehicle's system after tire rotations, sensor replacements, or tire changes. Perform this procedure outdoors for best results.
Step-by-Step Relearn Guide:
- Prepare the Vehicle: Ensure your vehicle is in the TPMS Learn Mode. This process varies by vehicle model, but typically involves setting the gearshift to "P" (Parking Mode) and putting the ignition switch to "ON". The vehicle's horn may beep twice to confirm entry into learn mode.
- Activate Sensors in Sequence: The relearn process starts from the front left tire.
- Hold the VXDAS EL-50448 tool against the sidewall of the tire, near the valve stem.
- Depress the "Learn" button on the tool while holding it against the tire sidewall.
- The tool's green "TX" LED will indicate it is transmitting.
- Once the vehicle's horn chirps or flashes, it indicates successful activation for that tire.
- Follow the Order: After the front left tire, proceed to the other tires in the following order:
- Front Right (Passenger Front)
- Rear Right (Passenger Rear)
- Rear Left (Driver Rear)
- Complete Relearn: After all sensors are reset, the vehicle's horn will typically chirp twice, signifying that the TPMS relearn procedure is finished.

Important Usage Tips:
- Position the antenna correctly when using the TPMS relearn tool.
- Expect occasional horn or flashing feedback after tire activation.
- This TPMS tool is a reset tool, not a sensor reprogramming device.
- Use original OEM sensors that are well-programmed for seamless operation.
