EL-50449 TPMS Relearn Tool for Ford – Tire Pressure Reset & TPMS Learning for Ford/Lincoln/Mercury

Short Version

The EL-50449 TPMS Relearn Tool is a practical tool for relearning tire pressure sensors on many Ford, Lincoln, and Mercury models. The tool is used when the car needs to relearn the position of each TPMS sensor, for example after a tire change, tire rotation, TPMS sensor replacement, or when the TPMS warning light is on after wheels/sensors have been moved.

On many Ford vehicles, the car's control system needs to know which sensor is located at the front left, front right, rear right, and rear left. If the wheels are moved between positions, the car may show the wrong wheel position or continue to warn about tire pressure even if the pressure is correct. With the EL-50449, you can activate the sensors in the correct order so that the car stores the correct sensor information again.

The procedure is done by putting the car in tire pressure training mode, holding the tool's antenna against the sidewall near the rim edge and valve area, pressing the start button, and waiting for confirmation from the car. Then, you continue in the standard order: front left → front right → rear right → rear left. When the last sensor is learned, the car normally confirms with a signal and exits the learning mode.

Please note: According to the product information, battery and charger are not included. The documentation also states that the battery should be charged for about 2 hours after use, so always check which version/battery type comes with your delivery.

What is EL-50449?

The EL-50449 is a TPMS activation tool used for relearning tire pressure sensors on many Ford-based vehicles. The tool helps the car read the sensor ID from each wheel position so that the tire pressure monitoring displays the correct information.

It is important to understand that the EL-50449 is normally not an advanced TPMS programmer for creating/programming universal sensors. The tool's main task is to activate the sensor when the car is already in relearn/training mode.

When do you need TPMS relearn?

A TPMS relearn may be needed when the wheel positions have changed or when the car no longer recognizes the sensors correctly. Common occasions:

• After tire rotation – when wheels are moved between front/rear or right/left.
• After wheel change – for example, switching between summer and winter wheels.
• After TPMS sensor replacement – if a sensor has been replaced.
• With TPMS warning – if the car shows a warning despite correct tire pressure.
• If the car shows the wrong wheel position – for example, if the front left is shown as the rear right.

How the tool works

Each TPMS sensor has its own ID. The car's control system needs to know which sensor is on each wheel position. When you put the car in TPMS learning mode, the car waits for each sensor to be activated in a specific order.

The EL-50449 is held against the tire sidewall near the valve area. When you press the start button, the tool sends an activation signal to the sensor. If the car receives the sensor's information correctly, the car normally confirms with an audible signal, and the next turn signal/position indicates which wheel needs to be read.

When all four sensors are read, the car's Body Control Module normally exits the learning mode and saves the new positions.

Step-by-step: use on Ford

Step 1 – Put the car in tire pressure training mode

The procedure may vary slightly between models. According to the product information, the following method is often used:

1. Park the car safely.
2. Apply the parking brake.
3. Turn the key/ignition from OFF to ON three times.
4. Depress/release the parking brake according to the car's procedure.
5. Turn off the ignition.
6. Turn from OFF to ON three times again.
7. When training mode is activated, the car normally confirms with an audible signal/horn or turn signal.

If your car has a different procedure in the owner's manual, always follow the car's own manual.

Step 2 – Read the front left wheel

1. Start at the front left wheel.
2. Hold the tool's antenna against the sidewall near the rim edge and valve area.
3. Do not place the tool directly on top of the valve stem – hold it near the area between the tire and rim at the valve.
4. Press and release the start button on the EL-50449.
5. Wait until the car confirms with an audible signal.

Step 3 – Continue with the next wheel

Once the first sensor is read, the car normally shows the next position via turn signal/indication. Continue in the order:

1. Front left
2. Front right
3. Rear right
4. Rear left

Step 4 – Complete the procedure

When the rear left sensor has been read and the car confirms with a signal, the learning is normally complete. The Body Control Module then exits the relearn mode and saves the sensor positions.

Step 5 – Check the result

1. Turn off the ignition.
2. Start the car or turn the ignition on again.
3. Check that the TPMS light turns off.
4. Drive a short distance if the car needs to update the pressure values.

Correct wheel order

The standard order according to the product text is:

If the car indicates a different order in the display/manual, the car's instructions should be followed.

Important tips for use

• Hold the tool near the tire sidewall at the valve, close to the rim edge.
• Do not place the tool directly over the valve stem – move it around the valve area slightly if the sensor does not respond.
• Ensure the tool has sufficient battery/charge.
• Perform the relearn procedure in a quiet environment so you can hear the car's audible signals.
• Proceed directly to the next wheel when the car confirms a sensor.
• Always check tire pressure manually with a tire pressure gauge.
• If the car does not accept a sensor, the sensor may be defective, incorrectly programmed, or of the wrong type.

Troubleshooting

The tool does not activate the sensor

• Check that the car is in the correct training mode.
• Hold the tool closer to the valve area.
• Try moving the tool around the tire sidewall near the valve.
• Check the battery/charge in the tool.
• Check that the TPMS sensor is not defective.

No audible signal from the car

• The car may not be in relearn mode.
• The wrong wheel order may have been used.
• The TPMS sensor may be the wrong type or have a dead battery.
• Some models require a different procedure than the standard method.

The car exits training mode before all wheels are complete

• The procedure may have a time limit.
• Start over from the beginning and move faster between the wheels.
• Follow the exact order: front left, front right, rear right, rear left.

The TPMS light remains on after relearn

• Check the tire pressure in all wheels.
• A sensor may be broken or have a dead battery.
• Sensors may need to be programmed with a separate TPMS programmer if they are universal sensors.
• The car may need to be driven a short distance to update values.
• There may be a stored TPMS fault that requires a diagnostic tool.

Wrong wheel position displayed

• The learning was likely done in the wrong order.
• Repeat the procedure and follow the car's turn signal/wheel indication.
