The diagnostic information of the BD-2 (On Board Diagnosisphase-2) system and the in-vehicle diagnostic system for domestic use has been output by a dedicated reading diagnostic device and used as maintenance information together with the off-board CPU diagnostic device. However, currently, the on-vehicle diagnostic device is an obligatory device that voluntarily regulates the exhaust gas deterioration rate so as not to exceed three times the regulated value, and is not for failure diagnosis. In-vehicle failure diagnosis is difficult to complete due to the manufacturer's warranty and has not been put to practical use. These pieces of diagnostic information are not displayed on-board as diagnostic results.

In the present invention, instead of newly installing a sensor exclusively for failure diagnosis, a main system of an automobile, that is, an engine, a vehicle (wheel, suspension, brake, steering),
The main purpose is to share sensors used for control, alarm, and display in information transmission (instrument panels and airbags). The sensor in bold red shown in the area of the active sensor in the drawing is also used as a sensor, and information of an existing diagnostic device such as a chassis (vehicle) self-diagnosis or a fuse monitor may be diverted.

失火,点火時期制御系統の不具合と判断する。The failure diagnosis of the engine ignition system 21 uses the ignition timing control unit in the engine electronic control system as it is. That is, a trigger is generated for each cylinder at an ignition timing according to the engine operating condition from the start to the stop of the engine. The presence or absence of this trigger is monitored by the diagnostic terminal 22 shown in the table. If no ignition pulse is generated due to engine rotation other than cranking, it is determined that the ignition plug has misfired or the ignition timing control system is defective.

7を待つ。In FIG. 4, the drive recorder 41 of the in-vehicle system 40 takes in a measured value only when the measured value exceeds a predetermined range in order to use the memory capacity efficiently (the measured value is measured within a predetermined time or more). Data (email) transmission when the number exceeds. If the user does not replace the part based on the diagnosis result by himself / herself, and selects a part purchase dealer from A and B, the navigation screen 34 displays a route to the selected dealer. Until the measured value is determined to be an abnormal value, the reliability of the determination is increased by providing a condition that the abnormal value is reproduced a predetermined number of times during a predetermined time. For example, the engine cooling water abnormal temperature is experimentally set to a slice level of 75 ° C. at the position of the water temperature sensor 42. At this time, a wear check is performed based on the thickness of the brake pad 43, and 1
The result of 4mm is also output.
There is no problem level. As illustrated in the figure, the maintenance data 44 is stored as a list of a car ID, a test date and time, a tester, a test item, test result data, and a result evaluation (a target portion and a measured value are level determined). . The diagnosis information and the dealer list are transmitted. This data is stored in the memory of the in-vehicle diagnostic device, and is also transmitted to the service company 45 that has made a maintenance contract to share the data. On the service company side, the mechanic looks at the data, comments to the user at 46, and replies to the maintenance order from the user.
