Dash flashes service......During write
2011 CTS-V.
During a flash sometimes the dash info center will ding chime first and then flash service stabiltrac-service suspension etc....not everytime I flash a tune
Now the flash doesn't get interupted and my changes seem to take effect. I'm just wondering if I should reflash to make sure the flash went in properly. Or it's just a little hicup from time to time during a flash. Maybe from the BCM? Happens during ECM or TCM flash.

the instrument cluster loses communications with many modules during reprogramming this is normal.

Yup, flashes all sorts of weird stuff. Totally normal.

Thanks. Good to know that when it happens it's nothing to worry about.
