Sounds like a loose cable causing a voltage problem. The error lights you mention won't clear with basic scanner but usually will clear after driving if the error that causes them clears.

Pull up the voltage reading and do the hood slam again but try it softly first.

Soft close happens again : somehow the alarm switch or an out of place wire is the problem. Only happens when slammed: loose wire getting shaken. An open or short on a critical operational wire like CPS will kill the engine which will shut off the power and can cause any sort of error.
