- step S11 the CPU 50 of the external diagnostic device 14 checks various parameters and establishes a communication state with the engine ECU 24.
- step S12 the fuel consumption acquisition unit 58 of the CPU 50 requests the engine ECU 24 to transmit the fuel consumption Afp (transmission of the request command).
- the engine ECU 24 that has received the request command reads the fuel consumption Afp from the RAM 36 and transmits it to the external diagnostic device 14, and the fuel consumption acquisition unit 58 of the external diagnostic device 14 receives the fuel consumption Afp from the engine ECU 24 in step S13. To receive.

- the worker who confirms the determination result pays out the vehicle 12 to the distribution process which is the next process.
- step S14 NO
- the amount of fuel consumed by the vehicle 12 during running or idling in the factory fuel consumption Afp exceeds an appropriate range.

- the characters displayed on the display unit 64 may be blinked or a warning sound may be emitted from the speaker 66.
- the operator who confirms the display can perform necessary refueling according to the value of the fuel consumption amount Afp.
- the "comparative example” described in the upper part of FIG. 5 is a virtual example for explaining the initial refueling amount for the vehicle 12.
- this "comparative example” for example, a total of 10.0 [L] is refueled as the initial refueling amount in the production line.
- the breakdown of the initial refueling amount in the "comparative example” is 2.25 [L] of fuel required for the initial explosion of the engine and 1.0 [L] of fuel required for running and idling in the inspection process. 0.25 [L] as the fuel required for running in the factory excluding the inspection process and adjustment work, and the fuel required for the adjustment work when it is judged that adjustment is necessary in the inspection process and returned to the subsequent process. 0 [L], 3.0 [L] as fuel required for idling (idle) in the factory excluding inspection process and adjustment work, required for running and idling in the distribution process after the vehicle 12 is shipped from the factory. It is 0.5 [L] as fuel.
- the operator does not confirm the amount of fuel consumed by the vehicle 12 in the factory after the vehicle 12 is refueled on the production line. Therefore, the initial refueling amount in the "comparative example” is set to an amount with a margin assuming that the mileage in the factory is the longest and the idle time in the factory is the longest.
- the fuel consumption amount Afp actually consumed in the factory can be appropriately confirmed by using the external diagnostic device 14 (steps S15 and S16 in FIG. 4). Therefore, additional refueling can be performed for the vehicle 12 whose fuel consumption Afp exceeds the threshold Th. On the other hand, the vehicle 12 having a fuel consumption amount Afp of the threshold value Th or less is shipped from the factory without additional refueling.
- the fuel required for the adjustment work is 0 [L] and the fuel required for the idle is 1.0 [L] as compared with the "Comparative example”.
- the total amount of refueling is 5.0 [L], which is half the amount of the "comparative example”.
- additional refueling may be performed only for some vehicles 12 in which the fuel consumption amount Afp exceeds the threshold value Th. In this way, in the "example”, while reducing the initial refueling amount for the vehicle 12 to the minimum necessary amount, the fuel consumption Afp in the factory is appropriately confirmed and the fuel required for each vehicle is refueled without excess or deficiency. Therefore, it is possible to optimize the amount of refueling for the vehicle 12 at the manufacturing plant (the entire production factory of the vehicle 12).
- the threshold value Th set in the external diagnostic apparatus 14 is, for example, 1.0 [L] required for running (self-propelled) and idling in the inspection process, and the inspection process and adjustment work. 0.25 [L] required for running (self-propelled) in the factory excluding, and 1.0 [L] required for idling in the factory excluding inspection process and adjustment work, totaling 2.25 [L] ] Can be set to a predetermined value as the lower limit.
- step S17 of FIG. 4 when the notification prompting refueling is displayed on the display unit 64, the process related to the fuel consumption determination is terminated, but in the modified example shown in FIG. 6, step S17 is performed. The difference is that steps S18 to S20 are added later.
- step S17 a step of erasing (resetting) the fuel consumption amount Afp recorded in the engine ECU 24 and the previous fuel consumption amount Afb is added.
- the external diagnostic device 14 accepts the operation of pressing the fuel consumption amount erasing button (not shown) by the operator in step S18 after step S17.
- step S18 When the operator presses the fuel consumption erase button (step S18: YES), a clear command is transmitted to the engine ECU 24 in step S19.
- the engine ECU 24 Upon receiving the clear command from the external diagnostic device 14 in step S191, the engine ECU 24 erases (reset) the fuel consumption Afp of the RAM 36 and the previous fuel consumption Afb of the EEPROM 34 in step S192.
- step S193 the engine ECU 24 saves the erasure history in the EEPROM 34. Proceeding to step S194, the engine ECU 24 replies to the external diagnostic device 14 that the erasing process is completed.
- step S192 the fuel consumption amount Afp and the previous fuel consumption amount Afb may be erased at the same time, or one of them may be erased first and then the other may be erased.
- the external diagnostic apparatus 14 when the external diagnostic apparatus 14 receives a response from the engine ECU 24 that the erasing process is completed, the external diagnostic device 14 displays the erasing process completion on the display unit 64 in step S20, and ends the process related to the fuel consumption determination. ..
- step S18 If the operator does not press the fuel consumption erase button (step S18: NO), the clear command is not transmitted to the engine ECU 24. At this time, the process related to the fuel consumption determination is completed after the elapse of the predetermined time. Assuming that the fuel consumption erase button is not pressed, the operator wants to end the process by checking only the fuel consumption Afp value of the vehicle 12 and the judgment result of the fuel consumption judgment. doing.
- the vehicle 12 is refueled with fuel for running in the post-processes (here, the inspection process and the distribution process) of the assembly process by an automatic refueling machine or the like (step S21).
- step S22 the process proceeds to step S22, and in the inspection process, an operator inspects whether various inspection items such as welding installation and parts assembly need to be adjusted. Here, it is assumed that adjustment is not necessary (step S22: NO).
- step S23 the worker determines the fuel consumption amount using the external diagnostic device 14 (performs the fuel consumption amount determination process corresponding to steps S11 to S17 in FIGS. 4 and 6).
