what is a *flash* ?

i bought my '02 used, and i don't know the history. there could be some kind of program on it... i'm not sure.

i've just read about reflashes, but not clear what they are. if i search on 'what is' a reflash... the search engine chokes on too much...

if you bought a used 2.5 year old truck... would you go to the dealer and ask for a reflash? should they charge me for it?

thanks.

thanks.A "reflash" is just updated software for the trucks computers. There have been several updates since 02.

Go here http://calid.gm.com/vci/VINEntryPre.do and type in your vin. Select PCM/VCM then normal. You will see the updated calibrations and the reasons for updating. Then go back and check the TCM. If you want to get your truck reflashed a dealer might do it free with other services or they might charge. It takes 15 mins at the most.

thanks. would this clear up any kind of monkeying they might have done with a programmer?
