I hooked up the scanner today, and I can not say for certain that it will read your problem. The O2 sensor wouldn't be a probem, but can't say it will for the stability system. Looking at the schematics, it shows it is all controlled by the EBCM (electronic brake control module). The scanner did not find that specific module.
I have an email in to Auto Enginuity'* tech support, asking if it is supported. I haven't received an answer as of yet. If my experience with my son'* ABS system is any indicator, I expect to hear that it is not supported. Their answer on that was that it uses the older ALDL system for ABS, that they do not support.
I'd hate to have you drive all this way before I get an answer, and have it be a wasted trip for you.
