EL-50448 GM TPMS Tool – Tire Pressure Monitoring Sensor Activation Tool OEC-T5 For GM Cars

The GM TPMS Tool EL-50448 is created for GM vehicles equipped with 315 or 433 MHz Tire Pressure Monitoring Sensors (TPMS). After tire rotations or sensor replacements, a "Sensor Re-Learn Procedure" is required. This procedure ensures the TPMS system works correctly on the vehicle. The GM TPMS Tool supports most GM makes up to 2014 and later models. Its use guarantees proper sensor function after changes.

This dedicated GM TPMS Tool, model OEC-T5, offers accurate tire pressure sensor readings from 2012 onwards. It works specifically with select diagnostic tools. This specificity is essential for reading sensor IDs and reprogramming sensors properly. Without this tool, the body control module cannot properly save sensor data per tire location.

Before the TPMS operates accurately, the control module saves ID info for every sensor’s position. When tires or wheel speed sensors are changed, the GM TPMS Tool EL-50448 is necessary to read sensor IDs. Below is a table that details sensor reading methods after replacements:

EL-50448 Instructions:

The EL50448 tool is compatible with all General Motors vehicles such as Buick, Cadillac, Chevrolet, and GMC for the North American market. Use only OEM sensors or others compatible with the required frequency. This tool supports GM cars with 315 MHz or 433 MHz TPM systems. It does not work with aftermarket sensors on different frequencies.

User Guide for GM TPMS Tool:

• Step 1 – Enter learning mode: Set the gearshift lever in "P" and turn ignition to “ON”.
• Access the tire pressure display via the Driver Information Center (DIC).
• The DIC shows "Press Set / Ctrl to re-learn". Press the “Set / Ctrl” button.
• The vehicle’s turn signal flashes for 3 seconds and horn beeps twice, signaling learning mode entry.

• Step 2 – Read tire pressure sensor info: Start at the front-left wheel. Place the EL-50448 or J-46079 antenna near the valve core and rim sidewall.
• Activate the tool’s start switch to read sensor data.
• The horn beeps once indicating a successful reading.

• Step 3 – Read other tire pressures: Repeat for front-right, rear-right, and rear-left wheels, in order.
• Turn signals flash 3 seconds and horn beeps twice when learning is complete.

For GM vehicles with TPM systems, this trademark "Sensor Re-Learn Procedure" is vital after tire changes or sensor replacements. Use this specialized GM TPMS Tool EL-50448 to perform it efficiently.
