Only 75 USD to buy the El-50448 TPMS tool and haved done TPMS tire learn on my 2012 Chevy Sonic.
Here is my TPMS tire learn procedure.
Start from the front-left wheel
Make the 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
Note:
A sensor re-learn procedure must be performed after tire rotations, remote control door lock reveiver module replacement or tire pressure sensor replacement
Alll i did refer to El-50448 Tire Pressure Sensor TPMS OEC-T5 User Manual
