FMG wins, the 2010 model years owners manual states the valve stem pressure system is used to relearn the TPMS sensors

 

Not my 2010.

 

Just posting the owners manual from the website in your sig.

 

It must have changed in the 2010 MY. The OM I had said EZL50448.

 

I’ll research the TPMS years and see



This is the 2009 TPMS sensors relearn procedure

 

And from the 2008 OM I post these for future readers looking for the procedure for their year, to save them time

 

Why was I thinking I had a 2010? It was a 2011. My memory sucks.
I modify my statement: Some 2010 and all 2011 need the tool. They changed it sometime in 2010 before the 2011 MY started.

The stupid reason given is that if you are on a GM dealership lot and try to reset the positions on one car there is a possibility that other cars will respond. I guess they don't trust the rolling codes for the fob since that is the only way to get the RCDLR into learn mode, besides with a scan tool.

 

I thought you had a 2008 and then a 2011. They all look alike!

 

I got a $14 tool on eBay that relearned the wheel sensors.i replaced all 4 and originally it wouldn't recognize them at all. I activated learn mode and followed the lights around the car. Now they all work perfectly.

 

I put new sensors in a few months ago. Used the key fob method. They worked but would give errors about 30 minutes into driving it. Even messing up the others. And it was random. 2 rear...one front...1 front...etc. It went away after a while and they all work great. No idea what I did...i even went on a long drive recently and had no issues.
