For GM vehicles equipped with a 315 or 433 MHz Tire Pressure Monitoring TPM system, a sensor learning procedure must be performed after tire rotation, remote lockout receiver module, or tire pressure sensor replacement. This learning procedure can be performed using the EL50448 special tool. Also applies to 2014 GM models Tire pressure sensors on 2012 and later models can only be read with certain designated diagnostic tools. Before the tire pressure monitoring system will function normally, the body control module will record the ID information for each position in the tire pressure sensor after replacing a tire or wheel speed sensor, use the following method to read the tire pressure sensor.For the specific method, please refer to the following Step 1 Enter the tilt mode and set the gear lever to When the learning is complete, the turn signal light will illuminate for 3 seconds and the horn will chirp twice. For some equipped with a Tire Pressure Monitoring System TPM, after replacing the tire remote lockout receiver module or replacing the tire pressure sensor, a sensor learning procedure must be performed. This learning procedure can be performed using the special tool 50448 Compatible Vehicle List Charger and battery are not included in the package.Q What vehicles will the EL50448 work on the Chevrolet Colorado A As far as I know, this will work on 2012 and 2013 GM cars and trucks. It may also work on other makes and models. Before purchasing this unit, I did several searches on the internet and found that this model was often used eclusively on 2012 and 2013 General Motors. You should be able to find Coloradospecific information easily. I also learned that 2012 and earlier GM vehicles have a reset procedure that does not require a reset tool, so you may not need this unit at all. Q What GM cars will the EL50448 TPMS work on A I dont know what cars it will work on, but Im sure it will work on GM pickups from 2007 onwards. Thats what I use mine for. Very easy to use. High quality product. Q Its for a 2006 Ford epedition lt, thanks A No, this is for GM only.EL50448 Review 1. For Trucks and Cars Simple and inepensive, but works great. Much better than going to a dealer or tire shop to reset the pressure sensor. I use it on my truck and my wifes and it only takes a few minutes to reset all four wheels. 2. Shows correct low battery display I have never had my TP sensor programmed using the bleed method on my 2007 Tahoe. Before I had this tool I would just remember which tire was which when I spun them, but not anymore. Now I can reprogram them in seconds and the dash display correctly shows which tire is low. This tool should be included with the vehicle.3. Easy to Use The operation of this product is simple and straightforward. That said, spending that much just to spin your tires is hardly eciting, but considering how much a dealer would charge, it wouldnt take many service visits to pay for the device. As for operation, it does eactly what it says it does without any drama. Put the vehicle in recovery mode and press the button on the device as instructed in the owners manual.4. I cant believe I need a special tool to spin my tires. From what I understand, for 2010 2011 and older vehicles, you can use any large magnet to reset your tire pressure sensor. 2011 2012 and at least my 2013 Silverado, you need one of these gadgets. This one works like a champ, the one I found referenced via the GM website. 5. GM Coverage The bleed method is only validated on a 2011 Chevrolet Volt using the El50448 TPMS learn tool and I was able to program 4 TPMS in less than a minute. The El50448 can program TPMS in GM 20102013.
