Why did you plug a 'diagnostic machine' to the car? (Assuming, an OBDII reader) Some readers, if unplugged without shutting down their programs, cause the car's electronics to stay on, and drain the battery overnight.
Most common advice is to disconnect the battery ground cable for 15 - 20 minutes, which will reset everything. (Have your OEM radio's security code handy.)
