A procedure is introduced to operate a diesel engine, which has a catalytic converter with three-way conversion characteristics. An extrinsic signal is switchably coupled to the pin so that the second operational function can be used to operate on the extrinsic signal. The transmission further includes a plurality of clutches operable to selectively engage the multiple mechanical gear ratios, and a plurality of rotational speed sensors. Even if the surface of the auxiliary wiring is oxidized, an increase in connection resistance is prevented. Moreover, the transmission end of the print order information is altered depending on whether the printing process in the print order information is, for example, a printing process having a size not more than a predetermined size or a printing process having a size greater than the predetermined size. The processor then correlates the output signal associated with the one of the first and second opposing surfaces corresponding to the associated predetermined surfaces with the master characteristic patterns to identify the denomination of the scanned bill.
