SDM key relearn

Post by dkg »

Has anyone here been able to do an SDM key relearn in the BCM? I'm using tech2win with a vcxnano. The brake pedal relearn to works like it's supposed to and I can get the SDM key relearn to work on my 2008 Avalanche, but for some reason when I try on the Caprice (a 2011) the tech2 software sits there for a minute not doing anything then eventually says error connecting. It seems like I've searched the whole entire internet and haven't come across anyone else with the same problem. :?:
