FAQ
Q:What vehicles will EL-50448 work on? have a chevy colorado
A:From what I've read, this will work on 2012 and 2013 for GM cars and Trucks. It may also work on other makes and models. I did several internet searches before purchasing this device, and found that this model is often mentioned specifically for 2012 and 2013 for GM vehicles. You should be able to find specific information for your Colorado pretty easily. Also, I have read that there is a reset procedure for 2012 and earlier for GM vehicles that does not require a reset tool, so you may not need this device at all. :-)
Q:Which for GM automobiles will EL-50448 TPMS work on?
A: I don't know all the automobiles that it will work on but I know for sure that it works on late model for GM pick up trucks- 2007 on. That is what I use mine for. Very easy to use. Good quality product.
Q:Will it work on for ford expedition xlt 2006 , thanks
A: No, This is for General Motors vehicles only.
EL-50448 Reviews:
1.works on truck and car: Simple and inexpensive but works great. Much better than going to the dealer or a tire store just to get your pressure sensors reset. 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 using the "let air out" method on my 2007 Tahoe. Before I had this tool, I would just remember which tires were which when I rotated them, but no longer. Now, I can reprogram them in just a few seconds and the dash display correctly indicates which tire is low. This tool should have come with the vehicle.
3. Easy to use: The operation of this product is simple and straightforward. As stated it's hard to get excited about spending this amount of money just to rotate tires, but considering what dealers would charge, it would not take many trips service visits to pay for the unit. As far as working it does exactly what it says it will do with no drama. Put the vehicle in reset mode and push the button on the unit following directions outlined in the car owners manual.
4. I could not believe I needed a special tool to rotate my tires. From what I understand 2010 (2011?) and older vehicles, you can use any big magnet to reset your Tire Pressure Sensors. 2011 (2012?) and up to at least my 2013 Silverado, you need one of these gizmos. This one works like a champ, and is the one I found referenced through a for GM website.
5. Wide for GM vehicle coverage: The deflate method is verified ok only for Chevrolet Volt 2011 year, with the El-50448 TPMS relearn tool, I could get the 4 TPMS programmed in less than one minute. El-50448 could program TPMS for GM 2010-2013 year.
