The repair manual corresponding to abnormality is cut out in maintenance manual 201 which exists in memory 101, and maintenance manual download routine 221 is notified to the car where the breakdown occurs by Internet 103. It is necessary to impose the charge corresponding to the use frequency on the manual user, and manual charge accounting program 222 is a program which calculates this use charge.
 The processing flow of maintenance manual download process 220 is shown in FIG. 24. Maintenance manual download routine 221 retrieves the repair manual which corresponds abnormally to prime (processing 340), and, next, notifies the breakdown car the repair manual retrieved through the Internet (processing 341). Manual charge accounting routine 222 adds the manual down-loading frequency of the owner of the breakdown car (processing 342), and collects the charge according to the manual down-loading frequency at the end (processing 343). Can the invoice be newly issued or the manual charge be collected by the method of the addition to the member charge etc.
FIG. 12 shows the data flow on the breakdown car after maintenance manual is actually notified. Repair method screen 202 which maintenance manual display process 200 accepted from cellular phone 111 is displayed on display 110.
 Next, the fourth embodiment to diagnose abnormal state of the car by off-line is explained. An abnormal value of the vehicle control data is stored on memory card 173,174 as shown by a first embodiment. At this point, other memory card 174 is taken out, and can be sent to the service company. The car can run straight even if one memory card is sent, and a new, abnormal data keeps being stored on the other memory card.
 The embodiment diagnosed by off-line is shown in FIG. 13 by using other memory card 174. Vehicle information data update routine 181 and break-down diagnosis routine 182 in abnormal, analytical process 180 are the same as a first embodiment. These read directly, and diagnose the break-down in memory card 174 of abnormal data. The car user returns diagnosis result 230 with memory card 174.
 Returned memory card 174 is installed in the vehicle again, and stores abnormal data. The example of inserting memory card 174 again is shown in FIG. 14. Here, there is a possibility that a new, abnormal data is stored on memory card 173 while memory card 174 is being detached. Therefore, the data copy is executed in this case by abnormal data copy process's 240 being started between two memory cards. As a result, the coherence of data between two memory cards comes to be achieved again.
FIG. 25 shows the processing flow of abnormal data copy process 240. In a process concerned, the content of memory card 173 is copied onto memory card 174 only when it is checked whether the memory card was newly inserted (processing 350), and is inserted (processing 351).
 It is also possible to achieve the fifth embodiment by which the used car is assessed by applying the fourth embodiment. The example of composing the server computer when the used car assessment business was done to FIG. 15 was shown. Obtaining memory card 174 or the vehicle number starts used car assessment process 250. Breakdown calendar retrieval routine 251 retrieves the breakdown calendar and the accident calendar of the vehicle from data or the vehicle number in the memory card. Vehicle assessment routine 252 outputs the amount of money of the assessment of a pertinent car by using these vehicle careers. Those who request the assessment return assessment data 253 to which the amount of money of the assessment, the breakdown calendar, and the accident calendar, etc. are shown with the memory card.
 The processing flow of used car assessment process 250 was shown in FIG. 26. Breakdown calendar retrieval routine 251 retrieves data corresponding to a pertinent vehicle from the vehicle information data base to prime (processing 360), and, next, acquires the breakdown calendar of a pertinent vehicle and the accident calendar (processing 361). Vehicle assessment routine 252 calculates the value of each parts (processing 362), adds the price of the main body of the vehicle calculated in the price with premium and the production fiscal year, etc. finally, and derives the assessment result (processing 363).
 Next, the sixth embodiment by which the accuracy of the break-down diagnosis is improved adding the improvement to a first embodiment is explained. FIG. 16 is a configuration of server computer 100 which composes the sixth embodiment. Running test instructin routine 260 is newly established in abnormal, analytical process 180 in this embodiment. Running test instructin routine 260 is a processing program which directs the running test pattern by which necessary data can be acquired when break-down diagnosis routine 182 cannot uniquely diagnose the breakdown.
 The processing flow of abnormal, analytical process 180 by which running test instructin routine 260 is installed is shown in FIG. 27. From processing 300 to the same processing 306 as first embodiment (FIG. 20) Processing 370 is inserted in break-down diagnosis routine 181, and it is checked whether the break-down diagnosis is possible according to the acquired abnormal data. If it is possible to diagnose the break-down, the same processing as a first embodiment is done. When the break-down diagnosis is impossible, running test instructin routine 260 is started, and running pattern for acquiring the data necessary to diagnose is calculated (processing 371). Next, the calculated running test pattern is notified to the breaddown vehicle (processing 372).
 The composition of car navigation system corresponding to the sixth embodiment is shown in FIG. 17. In this embodiment, running pattern display process 270 which displays running test pattern 271 sent by the server computer on display 110 is installed. The car user drives according to the test pattern. A new, abnormal data is notified that abnormal data reporting process 121 detects abnormal data while driving the test pattern.
FIG. 28 shows the content of the processing of running pattern display process 270. The running test pattern is received from the Internet through the cellular phone etc. (processing 380), and the test pattern is displayed in the display (processing 381). It is an alternative way instead of displaying the pertinent test pattern on the display and allowing the automotive user to test the vehicle with the pertinent test pattern that the running pattern display process 270 performs a necessary test drive automatically. However, this alternative method cannot be applicable in view of safety when a pertinent car is driving on the public road. It is not possible to do.
 The service company can develop various service businesses by using the vehicle information data bases collected in the embodiment of the present invention. Here, the direct mail print service system which uses the vehicle information data base is explained as an example of the service business. The system equipped with print service process 280 in FIG. 18 is shown. Maintenance company 131 is about to send direct mail to a plurality of car users for the commercial expansion. In this case, maintenance company 131 notifies the retrieval data to which the user for the direct mail sending is shown through Internet 103. For instance ((age <40 years old) & (address <23 districts in Tokyo) & (The car inspection 1 month ago)), the retrieval data is sent. Vehicle information retrieval routine 281 acquires vehicle information corresponding to the retrieved data from the vehicle information data base 102. Owner acquisition routine 282 takes out owner information on the vehicle corresponding to acquired information, and requests direct mail print routine 283 to print out direct mail from 284.
FIG. 29 is processing flow of print service process 280. The vehicle list corresponding to the retrieval data is acquired vehicle information retrieval routine's 281 retrieving the vehicle information data base to prime (processing 390), and continuously (processing 391). Owner acquisition routine 282 acquires the owner list of the retrieved vehicle (processing 392), obtains the owner's name next, and the list of the address is obtained (processing 393). Finally, the charges according to the number of prints is processed for the maintenance company which has been being requested (processing 395) while direct mail print routine 283 prints mail on those who have each place (processing 394).
 Finally, information in the present invention and the flow of money are shown in FIG. 30. The suppliers of information and money in the present invention include service company 400, user 401, automaker 402, non-life insurance company 403, private company 404, and maintenance company 405. Service company 400, user 401, and maintenance company 405 use everything of FIG. 29 from FIG. 1 and the main component of the system which explains. The service company receives fee 411 from the user, and when breaking down, does dissemination 410 such as maintenance company. Here, choices that fee 411 is free are possible, too. That is, the service company is a method of earning the income by the introduction fee etc. Obtained from maintenance company etc. The relation between the service company and maintenance company consists of information sales 415 (maintenance company introduction to the user) and the introduction fee money 414 as mentioned above. When the member introduced by the service company does the maintenance order to correspondence maintenance company, maintenance company pays introduction fee money 414. Moreover, the relation same as the current state of paying maintenance money 413 to servicing 412 is approved among maintenance company 405 and users 401. It is the explained one in FIG. 29 from FIG. 1 of the present invention above in brief the explained relation.
 Automaker 402 and private company 404 besides these can join. Automaker 402 and private company 404 can respectively receive dissemination 421,423 by investing in the establishment of service company 400 420,422. Acquired information is used to offer service to an individual customer in automaker and a private company. Automaker 402 buys the on-vehicle diagnostic system which shows to FIG. 1 from service company 400 again 419. This system is installed in the car merchandized by the automotive company or its auto dealers, and sold to the user 417. The payment for the car sales 417 is passed from the user to the automaker, and the payment for the purchase 419 of the on-vehicle diagnostic system passed from the automaker to the service company.
 Finally, it is added that non-life insurance company 406 can participate as another component of this system. That is, it is also possible that this on-vehicle remote diagnostic system is not only a diagnosis of the vehicle breakdown but also does an urgent report at the accident. Dissemination 424 at the accident can be done from the service company to non-life insurance company by using this. Non-life insurance company invests in the service company or pays money 425 to an individual dissemination. Non-life insurance company does insurance contract 427 to an individual user, and receives contract money 426. As non-life insurance company which participates in this system can receive the dissemination at the accident, they can easily do the accident analysis. Moreover, the user comes also to bear a safer drive in mind when recognizing that a on-vehicle remote diagnostic system can be used to process the accident. Insurance can be relatively discounted from these effects, and the user, non-life insurance company, and the advantage for tri-party of the service company are caused.
 The service company entered between the user and maintenance company by using the drawing, and the business model by which the breakdown measures and the maintenance estimation were supported was explained above. In this case, the charge which the user bears by this newly lying between dealings in the organization which did not exist so far improves or the margin of maintenance company decreases to the service company. If motor vehicle department gate of car dealer or principal occupation maintenance company rationalizes the business with this break-down diagnosis software so far, the user also is few the reactionary of the charge improvement or has the possibility to make to 0. In this case, the above-mentioned service company will integrate with maintenance company.
 Anyway, it is necessary to buy new software, and allocate the employee who takes charge of the break-down diagnosis and the maintenance estimation by the personal computer. However, the cost as the whole can be decreased by concentrating the break-down diagnosis and the used car assessment, etc. Which have been distributed to each maintenance company and the used car sales companies so far and doing. Moreover, it is also possible to develop a new business to serve the direct mail print as shown at the end of the embodiment.
 It is useful for the foresight diagnosis before break-down of major component parts, because the break-down diagnosis always monitors the operation of principal part goods of the vehicle, the change point of operation is caught, and abnormal data is recorded according to the present invention. Concretely, the precautions report is issued to the user before break-down accompanied with severe running break-down and thus, the driver can take such an effective and saver action that he she can drive the vehicle by itself without help of a towing truck even in an emergency operation.
 In addition, the maintenance can be ordered with an optimum charge by comparing the estimates from several companies.
