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.
