TPMS Relearn Tool – Automotive Tire Pressure Monitor System Activation and Reset for GM Vehicles – Car Accessory for Tire Sensor Programming

Specifications:

Material: ABS

Color: Orange + Black

Size: 6.1 x 2.4 x 1.4 Inches

Package Include: 1 x Relearn Tool for Auto Tire Pressure Monitor Sensor

The sensor re-read-in read-in procedure must be executed after each tire change, body Regulate module replacement, or sensor replacement. Once the reread mode is enabled, the identification code for each sensor will be read into the body Regulate module memory. When a sensor identification code is read, the body Regulate module causes the horn to chirp to indicate that the sensor has sent an identification code and that it has been received and read by the body Regulate module. The body Regulate module must read the sensor identifiers in the correct order to resolve the correct sensor location.

▲The first code read is assigned to the left front position, the second to the right front position, the third to the right rear position and the fourth to the left rear position. The turn signal lights will illuminate one at a time to indicate the correct order of the read positions.

①Use the EL-50448 or equivalent to diagnose sensor function

Each sensor has an internal low frequency coil. When tire pressure monitoring is used in enable mode, a low frequency transmission signal will be generated to activate the sensor. In read-in mode, the sensor responds to the low-frequency activation by transmitting the signal. In Tire Pressure Monitor Read-In Mode, when the Body Regulate Module receives a Read-In Mode transmission signal, it assigns the sensor identification code to the vehicle location corresponding to its read-in sequence.

②Sensor Function – The usage of the Pressure Increase/Decrease Method

In standstill mode, each sensor takes a pressure measurement sample every 30 seconds. If tire pressure increases or decreases by more than 8.3 kPa (1.2 psi) from the last measurement, a re-measurement will be taken immediately to confirm the pressure change value.

Synopsis:

It is a tire pressure reset instrument, or learning motion.

After each tire shift, tire, body Regulate module, and tire pressure sensor replacement, the sensor re-matching procedure must be performed to ensure the correctness of the tire pressure value acquisition display.

Operation steps:

1. Make sure the vehicle is in the TPMS learning state/mode.

2. Follow the automotive maintenance procedures, holding the instrument in order (left front, right front, right rear, left rear), aligned with the valve core lever (the mouth of the gas) near the tire sidewall to press the reset button.

3. At this time the green LED light (TX light) will light up, that is, to send a signal, when you hear the car beeps after that is a successful match.

4. Match other tires in turn.

EL-50448 instructions:

EL50448 works on all General Motors products manufactured for the North American market. It won’t work if you’ve purchased aftermarket sensors that are the fallacious frequency. EL50448 fit for G.M most kind of vehicles, equipped with a 315 or 433 MHz Tire Pressure Monitoring (TPM) system. This re-learn procedure can be performed by The usage of special tool EL-50448.

How to use EL 50448 TPMS Activation Tool

Step 1- Enter leaning mode

Set the gearshift lever to “P”

Put the ignition switch to “ON”

Enter the interface of tire pressure display by DIC

DIC shows “Press Set / Ctrl to re-learn”

Press “Set / Ctrl”

The turn signal is lighted for 3 seconds and the horn beep sound twice to enter the learning mode

Step 2- Read tire pressure sensor information

Start from the front-left wheel,

Make the J-46079 or Diagnostic Tool EL-50448 antenna up against the valve core position & close to the rim of the tire sidewall

El-50448 tire pressure tool starts by the start switch

Successful to read the tire pressure sensor information when the horn bleeps once

Step 3- Same method to read other tire pressure information

Follow the instuction above to read tire pussure of the front-right, rear-right, rear-left wheels.

Turn signals is lighted for 3 seconds and the horn bleeps twice when the learning is complete.

For certain vehicles equipped with a Tire Pressure Monitoring (TPM) system, a “Sensor Re-Learn Procedure” must be performed after tire rotations, Remote Regulate Door Lock Receiver Module replacement or Tire Pressure Sensor replacement. This re-learn procedure can be performed by The usage of special tool 50448

【Standard Specifications】: OEC-T5 specifications, EL-50448 measures approximately 6.1 x 2.4 x 1.4 inches and is comfortable to hold. It uses a 9V battery and has an operating temperature of -20~80°C. With it, individuals can easily complete the relearning of the vehicle pressure sensor, which can greatly save time and money on trips to the auto store.
【Activation Reset Function】: It is a must-have learning tool for replacing tire pressure sensors, removing tire pressure alarms or replacing tires. With a powerful activation reset function, quickly and easily reset your tire pressure sensor to keep your vehicle’s tire pressure monitoring system operating optimally. For instructions on how to use this product take a look at Product Description.
【Vehicle Universal】: Our activation tool is universal for most cars on the market, such as sedan, SUV, pickup truck, etc., not for large trucks. EL-50448 fits Enclave, Encore, LaCrosse, Regal, Camaro, Corvette, Traverse, Malibu. Please carefully identify the proper fit for your vehicle. (Different vehicles may take different amounts of time to reset all tire sensors after rotation.)
【Easy to Use】: Make sure your vehicle is in learning mode and follow the maintenance procedures. Place the tool firmly against the tire sidewall, near the valve stem. Even as holding the tool against the tire sidewall, press the learn button. (Note: Make sure the battery is in good condition and the antenna is in the correct position when The usage of)
