Problems solved by technology

[0006] The manufacturer of the vehicle parts sends engineers to the vehicle manufacturer or the vehicle repair organization to assist in obtaining the type and cause of the failure of the vehicle parts. It is true that the key product information of the vehicle parts will not be disclosed, but it will cost Longer time and more expense, resulting in higher repair costs

Embodiment Construction

[0017] According to the solution provided by the embodiment of the present invention, the mapping relationship between the internal fault codes of various faults that may occur in vehicle components and the flashing codes that do not contain the product information of vehicle components is established in advance (the mapping relationship does not support the manufacturing of vehicle components. other than the manufacturer’s engineers so as not to leak the product information of the vehicle components) and store it in the electronic control unit (ECU: Electronic Control Unit) of the vehicle components, and then when it is necessary to indicate the failure after the failure of the vehicle components , the electronic control unit of the vehicle component obtains the internal fault code of the fault of the vehicle component from the vehicle component, and then retrieves the flashing code mapped to the obtained internal fault code from the stored mapping relationship, and finally pre...

Abstract

The invention relates to a method and a device used for indicating faults. The device comprises an acquiring module, a retrieving module and a presenting module, the acquiring module is used for acquiring internal fault codes of the faults of vehicle parts on a vehicle, the retrieving module is used for retrieving glittering codes mapped with the acquired internal fault codes from a mapping relationship between the internal fault codes, of the faults, prestored in the vehicle parts and the glittering codes, and the presenting module is used for presenting the retrieved glittering codes to indicate the faults. By the method and the device, types and reasons of the faults can be acquired in a low-cost manner without leaking product information of the vehicle parts.

Description

technical field [0001] The invention relates to the field of vehicle fault diagnosis, in particular to a method and device for indicating faults. Background technique [0002] Vehicles are assembled from multiple vehicle components. These vehicle components include, for example, the engine, transmission, oil supply system, cooling system and the like. During vehicle production or daily use, vehicle components may fail, so it is necessary to eliminate the failure of vehicle components so that the vehicle can operate normally. [0003] In order to eliminate the faults of the vehicle components, it is first necessary to obtain the type and cause of the faults of the vehicle components. Typically, vehicle components that fail generate internal fault codes that can be used to indicate the type and cause of the failure. Therefore, by using the internal fault codes, it is possible to conveniently check out the types and specific causes of faults in vehicle components. [0004] ...
