I'm unaware of what the scanmaster codes are. But with the XFI codes, a code 25 would be 16+8+1. So, three codes. I would log into your XFI and look at both error code 1 & error code 2 and see what the xfi reports.
The SES light came on after a spirited run which prompted me to look at the codes. This happened a few weeks ago as well but I never got around to researching it. Car runs great and thought it was a boost error.
