Trying to figure out how to scan other modules in the vehicle for trouble codes. My wife's Yukon just came up a couple days ago with a Service Traction Control and Service Stabilitrak message, but no codes are coming up. I tried going into Edit --> Preferences --> Options tab and checking Active Module detection, but when I do that EFILive scans for modules and says "Searching for ECM and TCM only" or something like that. I thought I remembered using EFILive to scan for airbag module codes on a 2001 about a year ago, or at least reset the codes. Anyone know how to do this?
