In another post on another forum, I saw someone reference this SPS website (tis2web.service.gm.com). So, I plug in my VIN number and head over to say, ECM calibration and then click "engine operation" and here's what it shows me:
CPart Number CVN Description
12652773 00008181 New calibration to address customer complaint related to 5-4 downshift.
12646227 0000DB3A New calibration to enhance the operation of the engine oil life monitor to more accurately identify the required oil change interval.
12644198 00001EED New calibration to reduce the potential for engine stall during hard turn, and improve misfire converter protection.
12642531 000059FE New calibration with enhanced misfire detection on startup.
12641279 000048C3 New calibration for start of production.
12640367 00009220 Engine Operation[/color]
My question is this - are these things listed updates that have been performed on my vehicle? OR, is this a listing of available updates specific for my VIN ....that could be performed in the future?
Thanks in advance.
