Car won't start after clutch repair on 2006 Acura TSX

Hi, I got my clutch replaced last week. Car stalled on the highway on the way home from the mechanic. Dealer now tells me that they need to replace the computer circuit board ($1000) just to diagnose what the problem is because they cannot access the system. What happened??? Is there a way to diagnose to problem without first replacing the board? Thank you
