3.2 Entering TPMS Relearn Mode
The procedure to enter TPMS relearn mode varies by vehicle model. Consult your vehicle's owner's manual for the exact steps. A common method for Ford vehicles involves a sequence of ignition cycles and brake pedal presses. Ensure your vehicle is in the correct relearn mode before proceeding with the tool.
3.3 Activating TPMS Sensors
Once the vehicle is in TPMS relearn mode:
- Hold the EL-50449 tool with the antenna positioned against the tire sidewall, near the valve stem.
- Ensure the antenna is parallel to the valve stem for optimal signal reception.
- Press and release the power button on the tool to activate the sensor. The TX pilot light will illuminate.
- Listen for a horn chirp from the vehicle, indicating successful sensor activation.
- Repeat this process for each tire in the specified order (typically Front Left, Front Right, Rear Right, Rear Left).

4. Maintenance
Proper maintenance ensures the longevity and reliable operation of your JDIAG EL-50449 TPMS Relearn Tool.
- Battery Replacement: Replace the 9V battery when the "LOW BAT" indicator light illuminates. Always use a new, high-quality battery.
- Cleaning: Wipe the tool with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the tool in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
5. Troubleshooting
If you encounter issues while using the EL-50449 tool, consider the following:
- Tool Not Activating Sensors:
- Ensure the vehicle is correctly in TPMS relearn mode.
- Verify the tool's antenna is positioned correctly and parallel to the valve stem.
- Check the battery. If the "LOW BAT" light is on, replace the 9V battery with a new one.
- Confirm the TPMS sensors are original and properly programmed. Non-original sensors may not be compatible.
- "LOW BAT" Indicator: This indicates the 9V battery needs to be replaced. A weak battery can lead to insufficient signal strength for sensor activation.
- No Horn Chirp: If the vehicle does not chirp after activating a sensor, it indicates the sensor was not successfully activated. Re-check tool positioning, battery, and ensure the vehicle is still in relearn mode.
- Incompatible Vehicle: This tool is not designed for heavy trucks with more than 4 tires. Refer to the compatibility list in Section 3.1.
