Jeff Wilson Posted December 16, 2004 Report Share Posted December 16, 2004 A few days ago my 98 STS displayed "Change Brake Pads" I went to see my mechanic and we got to talking and he said that on Caddies they have computer updates every so often. He asked me for the serial # of my STS, he checked on the GM website and it came back that there are (8) updates for my car. I totally trust my mechanic I have just have never heard of this "computer updates" on vehicles, the industy I work in we do have computer updates I should know better this is a first for me. I have searched the site but haven't come up with anything relating to computer updates, unless I am not searching properly. Can anyone please shed some light?

Bruce Nunnally Posted December 16, 2004 Report Share Posted December 16, 2004 Cadillac routinely issues updates to the calibration in the PCMs. Sometimes these might address idle smoothness or other issues. It is not unusual to have your PCM reprogrammed during a dealer visit, but I think only if you actually have some issue that one of the calibration updates addressed.
