I think we've gotten to the right answer. GM changed the learning technique from using a magnet to needing a special tool. https://gmspecialservicetools.spx.co...s.aspx?id=5677
I don't think I'm going to rush right out and buy one but it is nice to finally get to the bottom of the TMPS question.
Today I tested a relearn tool (ATEQ VT5) from Tire Rack on my 2012 SRX. It worked like a charm and in less than (1) minute I had all four tires relearned. It sure beats the h@ll out of letting the air out and then adding air.
Just make sure that you press the tip of this tool on the side wall of your tire near the valve stem.
Staying with the 2012 models (Late 2011 models also) What is the part number for these new tire sensors? Someone said that it should be:
20922900 (GM Part number) Is this correct? and will older sensors from early 2011 and before work on the 2012? I think those may have a 25920615 or 20923680 numbers.
I had a donut magnet that you could use on some sensor as well. Those won't work anymore?
Owners Manual says to take it to the dealer OR talk with your dealer about a special tool to purchase. I rotate tires about every 3000-4000 miles, depending on use (it's just an OCD). Does anyone have a sync tool, probably Kent Moore, that will accomplish this? Is there another method? One of my neighbors mentioned a magnet??????
Merged into a thread all about tire learning tools and 2011+ SRXs with TPMS.
Also, if it hasn't been clarified, only a tpms re-learn tool will work. (Like a GM/Kent Moore EL-50448)
I just bought the tool for $80. These days, that seems dirt cheap to me.
Maybe somebody should start a tool rental like netflix.....
If you rotate your tires and want the display to show the appropriate wheel, then yes you need the tool for the vehicle to relearn the new positions.
If you keep track of which wheel is where, you dont absolutely need the tool.
