A trouble-diagnosable multifunction testing apparatus is disclosed for use with a first half part of a collective connector provided in an automotive vehicle, the first half part of the collective connector including a plurality of signal lines connected respectively to a plurality of electronic control units disposed in the vehicle for transmitting a trouble-diagnosis output signal or various data signals obtained from each of the plurality of electronic control units, and a common switchable signal line connected with each of the plurality of electronic control units for transmitting an electric signal having a first or second logic level, the first half part of the collective connector being connected operatively with both of the signal lines, respectively. When a conventional test unit is connected to the first half connector part, the electronic control units transmit data signals to it at a first rate. When a special high-speed test unit is connected to the fist half connector part, it places a signal on the common switchable signal line which signal causes the electronic control units to transmit data at a rate which is higher than the first rate.
