  • Patent number: 7558667
    Abstract: A vehicle including plural gas sensors assembled in plural exhaust systems, detecting an oxygen concentration in an exhaust gas, where an air-fuel ratio feedback control is carried out together with an engine control unit. Each gas sensor detects signal of oxygen concentration corresponding to a group of cylinders. The method for detecting an assembled state of the gas sensor: controls an engine control parameter affecting the air-fuel ratio of the engine, so that the values thereof are different from each other for the plural groups of cylinders corresponding to the plural exhaust systems; monitors an output from the gas sensor under the controlled state, the gas sensor being installed in each of the plural exhaust systems; and judges that the gas sensor is in a wrong assembled state if the output from the gas sensor is an abnormal output corresponding to the value of the engine control parameter.

  • Patent number: 7493455
    Abstract: To provide a memory-writing device which can simply and reliably write desired data to a nonvolatile memory of an electronic device, connection is made with an ECU to perform write processing to write write data from the memory-writing device to a flash ROM by copying a write-control program from the external portion to a RAM and executing the write-control program, and by sequentially sending the foregoing write-control program and write data to this ECU together with sending, at a predetermined timing, write-control information required for the ECU to execute the write-control program, the write-control program and the write-control information are stored in a freely attachable and removable first ROM and the write-control information stored in the first ROM is read and sent to the ECU at a memory-rewriting device to cause the write processing to be performed in the ECU. According to this device, an ECU of differing specifications can be supported merely by exchanging the first ROM.

  • Patent number: 7208329
    Abstract: In a side plate (52) of a retainer (50), a jig insertion groove (70) is cut at an upper end portion of its front edge. A releasing jig (J) is insertable into a gap between the bottom surface of the jig insertion groove (70) and a vertical front edge of a recessed surface (27) of a female housing (20). If the releasing jig (J) is rotated so as to be pried, the retainer (50) is pushed back diagonally downward along a guide groove (60) and reaches a temporary retaining position.

  • Patent number: 7056159
    Abstract: A male housing (20) is provided with cavities (23) for inserting male terminal metal pieces (10) in two upper and lower stages and a retainer mounting hole (27) opening the respective cavities (23) in a lower direction and in two side directions. The retainer (40) is mounted movably and skewedly to a direction of inserting and drawing the male terminal metal piece (10) between a full locking position permitting to insert and draw the male terminal metal piece (10) and a regular locking position locked to the male terminal metal piece (10).

  • Patent number: 7001206
    Abstract: A male housing (70) has a receptacle (71) for receiving a female housing (20). An introducing surface (77) is formed around the inner front edge of the receptacle (71). A retainer (40) for locking female terminal fittings has an interfering portion (49) that interferes with the receptacle (71) when the retainer (40) is at an incomplete mount position IMP. The interfering portion (49) has a guiding surface (50) for guiding the interfering portion (49) into the receptacle (71) when the retainer (40) is a full locking position. The interfering portion (49) has contact surfaces (57) and the inner front edge of the receptacle (71) has receiving surfaces (79) at positions corresponding to the contact surfaces (57) and backward from the introducing surface (77). The receiving surfaces (79) can achieve surface contact with the contact surfaces (57).

  • Patent number: 6799106
    Abstract: A vehicular electronic control system includes multiple electronic control units (ECUs) to which a tester is connectable for diagnosis. Each ECU stores a vehicle identifying number (VIN) code that is transmitted to the tester for providing various kinds of information on a vehicle. A priority level is assign to each ECU so that the ECUs transmit the VIN code in order of precedence when the ECU having higher priority is unable to transmit the VIN code when another ECU has not transmitted the VIN code. Moreover, each ECU monitors a communication line when received a VIN code transmission request from the tester and detects an output indicative the VIN code sent from another ECU to the tester. When the ECU has detected the output, it terminates the VIN code transmission and do not transmits the VIN code to the tester.
