Operating Instructions
Follow these steps to properly use the EL-50448 tool for TPMS sensor relearning.
Step 1: Set Your Car in TPMS Relearn Mode
- Ensure the vehicle's gear is in the P (Park) position.
- Using the vehicle's cruise control settings, navigate to and select the TPMS re-learn mode in the dashboard display.
- The vehicle's horn will sound twice, and the TPMS indicator light will flash, confirming that the learning mode has been successfully entered. If equipped, the message center may display a prompt for the front left (LF) tire.
- Once in relearn mode, the Body Control Module (BCM) is ready to record the ID information of each tire pressure sensor.
Step 2: Use the EL-50448 Relearn Tool
- Begin with the left-front tire. Hold the EL-50448 unit next to the tire valve stem, ensuring the tool's antenna is close to the tire sidewall.
- Press the white operation button on the tool. The vehicle's horn will bleep once, indicating successful activation of the sensor. The green LED on the tool will illuminate, signifying transmission.
- Proceed to the remaining tires in the following sequence:
- Front-Right tire
- Rear-Right tire
- Rear-Left tire
- After all four sensors have been reset, the vehicle's horn will sound twice, confirming that the TPMS relearn process is complete.

Maintenance
Battery Replacement:
When the "LOW BAT" indicator light on the tool illuminates, it signifies that the battery power is low and needs to be replaced. Refer to the "Battery Installation" section under Setup for instructions on replacing the 9V battery.
Always use a fresh 6F22 9V Lithium or NiMH battery for optimal performance.
Troubleshooting
If you encounter issues while using the EL-50448 tool, consider the following:
- Tool not activating sensor: Ensure the vehicle is correctly in TPMS relearn mode. Verify the tool is held close to the tire valve stem. Check if the battery needs replacement (LOW BAT indicator).
- Vehicle not entering relearn mode: Consult your vehicle's owner's manual for specific instructions on how to activate TPMS relearn mode. Ensure the gear is in Park.
- LOW BAT indicator: Replace the 9V battery as described in the Maintenance section.
