How to Use
- Enter Learning Mode: Place the gear lever in "P," set the ignition to "ON," and navigate to the tire pressure display interface via the Digital Instrument Cluster (DIC). Press "Set/Ctrl" when prompted — the turn signal will illuminate for 3 seconds and the horn will beep twice to confirm learning mode is active.
- Read Sensor Information: Starting with the left front wheel, aim the EL-50448 antenna at the valve core position close to the tire sidewall rim and press the start switch. A single horn beep confirms the sensor has been read successfully.
- Complete All Wheels: Repeat for the right front, right rear, and left rear wheels in sequence. Once all four are read, the turn signal illuminates for 3 seconds and the horn beeps twice to confirm completion.

Frequently Asked Questions
Q: Which vehicles is the EL-50448 TPMS relearn tool compatible with?
A: The EL-50448 TPMS Relearn Activation Tool is designed to work with most vehicles manufactured from 2012 onwards that use a standard tire pressure monitoring system. It is especially useful for models whose sensors require a dedicated activation instrument to complete the relearn process after a tire rotation or sensor replacement.
Q: Does the EL-50448 TPMS tool come with a battery or charger?
A: No — the tool requires one 9V battery for operation, which is not included in the package. A charger is also not included. Please purchase a standard 9V battery separately before first use to ensure the tool is ready when you need it.
Q: When should I use a TPMS relearn activation tool?
A: You should use a TPMS relearn tool any time you rotate tires, replace a wheel speed sensor, or install new wheels — situations where the vehicle's Body Control Module (BCM) needs to re-register each sensor's ID to the correct wheel position. Without relearning, the TPMS warning light may remain on even when tire pressure is correct.
Q: How do I know the EL-50448 has successfully read a sensor?
A: When the tool's antenna is positioned correctly near the tire's valve core and the start switch is activated, the vehicle's horn will beep once to confirm that the sensor information has been read successfully. After all four wheels are completed, the horn beeps twice to signal that the full relearn process is finished.
