Would it work with 2003 gmc yukon

[@EliTheOBDTech]

I believe it will, but you must have a capable scanner that can perform that function.

[@deangarcia449]

Whats the cost for this to be done?

[@EliTheOBDTech]

It all depends how much the shop charges per 1 hour of diagnostic

The test failed for the 2009 Tahoe. What is the problem?

[@EliTheOBDTech]

You need to meet certain parameters for the relearn to happen. The scanner should tell you the required procedures.

@@user-jp2lm5jz1q I not 100% sure, but the code(s) may be the reason why it fails. Are you able to erase codes? If yes, clear and then retry.
