TPMS Relearn tool

[iwaslowr]

Apparently the manual TPMS re-learn process changed between 2008 and 2012 models... Initiating the process by decreasing psi isn't working(may be bad/ruined sensors though). Has anyone had success manually sync-ing a 2012 using an alternative to the dealers "re-learn" tool?

I bought a TPMS relearn tool for about $70 the part # is EL-50448, if you google it you can find it also maybe on Ebay. I had the same problem trying to set my pressure and the tool worked wonders for me.

I just did mine it just took a long time for the horn to chirp and I had the rubber style valve stems which are the newer ones, just be patience and add a little over max psi before starting.

No tool for me on my 2011 Tahoe. Just let air out one tire at a time.
