How do you diagnose a problem with electronic shifting into 4 wheel drive on a Chevy S 10 pickup?

Well if there's a serious electrical problem it would probably set the check engine light off. Other than that, check the fluid level and if required change it. After that i'd have a tranny shop look at it, unless you suspect a particular part. Diagnosis on a tranny without proper tools is difficult if not impossible.
