For GM vehicles equipped with a 315 or 433 MHz Tire Pressure Monitoring (TPM) system, a sensor relearn procedure must be performed after tire rotation remote lock module replacement or tire pressure sensor replacement. This relearn process can be performed using the special tool EL-50448. Also fits 2014 GM models. Tire pressure sensors from 2012 and later models can only be read with certain designated diagnostic tools. Before the tire pressure monitoring system works normally, the body control module will record the ID information of each position of the tire pressure sensor after replacing the tire or wheel speed sensor, use the following method to read the tire pressure sensor. The specific method is as follows: Step 1 - Enter the pitch mode and place the gear lever in position. When the learning is complete, the turn signal light will illuminate for 3 seconds and the horn will sound twice. On some units equipped with a Tire Pressure Monitoring (TPM) system, a sensor relearn procedure must be performed after tire remote lock receiver replacement or tire pressure sensor replacement. This relearn can be performed using the special tool 50448 Compatible Vehicle List: Charger and battery are not included in the package. For trucks and cars: simple, inexpensive but effective. Much better than going to the dealer or tire shop to reset the pressure sensor. I use this on my truck and my wife's and it only takes a few minutes to reset all 4 wheels. 2. Show correct low battery display: I have never used the bleed method to program the TP sensor on my 2007 Tahoe. Before I had this tool, I could only remember which tire it was when I rotated it, but not anymore. Now I can reprogram them in seconds and the instrument display correctly shows which tire has a low battery. This tool should come with the vehicle. Easy to use: The use of this product is simple and straightforward. As mentioned before, it's not exciting to pay so much just to have the tires rotated, but considering how much the dealer charges, it won't take multiple service visits to pay for the unit. In terms of work, it does exactly what it says it does, without drama. Put the vehicle in reset mode and press the buttons on the unit according to the instructions in the manual. I can't believe I need a special tool to rotate a tire. As I understand it, on 2010 (2011) and older vehicles, you can use any large magnet to reset the tire pressure sensor. 2011 (2012) and at least my 2013 Silverado, you need one of these. This is like a master, I found it referenced via the GM website. 5. GM coverage: The bleed method has only been proven on an 2011 Chevy Volt using the TPMS learning tool El-50448 and I was able to program 4 TPMS in less than a minute. El-50448 can program TPMS in GM 2010-2013.
