What symptoms lead you to suspect the chip is bad? I ask because it's not a failure-prone part.?
?
The factory chips weren't officially able to be reprogrammed, though sometimes GM did use parts that could be erased. Dealers just replaced the chip. Newer GM cars have FLASH memory and those are reprogrammed via the data port.?
?
The last chip I bought from GM was about $40.?
?
If the ECM's part number (i.e. 1227730, probably not the one you've got but it's an example of what it will look like) is the same, then just change the chip and you're fine. GM used the same ECM for different cars and options over the years, but as long as the part number (a.k.a. service number) is the same, then you're fine.?
