Feature:Specification:Features 1.Works on truck and car: Simple and inexpensive but works great. Much better than going to the dealer or a tire shop just to reset your pressure sensors. I used it on my truck and my wife's car and it only took a few minutes to reset all four wheels on each. 2. With correct low battery display: I've never been able to get my TP sensors to program with the "let air out" method on my 2007 Tahoe. Before I had this tool, I would just remember which links were those when I rotated them, but no longer. Now, I can reprogram them in just a few seconds and the dash display correctly shows which band is low. This tool must come with the vehicle. 3. Easy to use: The operation of this product is simple and straightforward. As mentioned it's hard to get excited about spending this amount of money just to run tires, but given what dealers would charge, it wouldn't take many service trips to pay for the unit. As far as work it does exactly what it says it will do with no drama. Put the vehicle into reset mode and the button on the unit following directions outlined in the car owners manual. 4. Wide GM vehicle coverage: The deflate method has been verified ok only on Chevrolet Volt 2011 year, with the El-50448 TPMS relearn tool, I could get the 4 TPMS programmed in less than a minute. El-50448 could program TPMS on GM from 2010-2013 years. Specifications: Material: ABS Color: Red Package Includes: 1 X TPMS Activation ToolPackage List:Package Includes: 1 X TPMS Activation Tool
