Abstract
Abstract A fault diagnosis system is provided for vehicles having a pluarlity of automotive electronic devices which output fault diagnoses according to one of a plurality of output signal schemes disposed thereon. A vehicle-side connector includes pins for carrying signal lines for signals representing the results of the fault diagnoses output from the plurality of of electronic devices. The vehicle-side connector also includes at least one pin for carrying at least one control line for a signal designating a selected output signaling scheme to the electronic devices. One of a plurality of testers displays the results of the fault diagnoses on the basis of the signals transmitted from the respective electronic devices. Each tester has a tester-side connector which connects to the vehicle-side connector to connect the output signals from each of the electronic devices and the control signal for designating the selective signaling scheme.
