Cleared check engine light by battery disconnect now locked out

I replaced water pump and then removed negative battery cable to clear the code.. now all my warning lights all stay lit up on the dash and it won’t let me place car into drive or reverse.. I have tried reset this several times by same procedure with no luck.. I know I must of re set all defaults and lost communication with computer. Now I can’t even move the car.. how do I get this all synced again?
