Default Check Engine Light

My check engine light is blinking real fast and making a noice when it blinks. I hooked up my Smarty Jr. and try to connect it and I get a "Can Error #122 Wrong Communication". The truck cranks when I try to start it, but it won't start. Anybody have any quick suggestions???

Is there a onboard security system?

Nothing that is aftermarket. The security stuff is all regular factory issued.

I disconnected the batteries for 15 minutes this time and the error cleared. I still don't know what it means though.
