[0090] In one embodiment, as Figure 5 As described above, based on the first embodiment, the fourth embodiment of the diagnosis method for the combination instrument failure of the present invention is proposed, and the S30 includes:

[0091] Step S301, according to the abnormal code, obtain the serial number corresponding to the abnormal code.

[0092] It can be understood that after obtaining the abnormal code, each abnormal code has a number that can uniquely identify the abnormal code, and the number can be the ID number of the abnormal code, or it can be the ID number of the abnormal code. number, which is not limited in this embodiment.

[0093] Step S302, comparing the abnormality code with the preset diagnosis code, and obtaining the comparison result of the abnormality code and the preset diagnosis code.

[0094] It can be understood that the comparison of the abnormal code with the preset diagnosis code means that after the abnormal code is derived, the abnormal c...

Abstract

The invention relates to the technical field of combination instrument fault diagnosis, and discloses a combination instrument fault diagnosis method, device and equipment and a storage medium. The method comprises the steps: recording the abnormal information of a combination instrument during the operation of the combination instrument, and obtaining a preset design rule; compiling the abnormalinformation according to the preset design rule to generate an abnormal code; obtaining a preset diagnosis code, and comparing the abnormal code with the preset diagnosis code; and positioning the abnormal information according to a comparison result to obtain a fault range of the combination instrument. According to the invention, due to the fact that the abnormal information is compiled into theabnormal codes, the problems of the combination instrument can be directly converted into the corresponding abnormal codes, the abnormal codes are compared with the preset diagnosis codes, and the fault range of the combination instrument is positioned, so that compared with the prior art that a corresponding fault piece needs to be taken for analysis, the method of the invention has the following characteristics that the position of the fault can be found more quickly and effectively so as to improve the troubleshooting efficiency.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis of a combination meter, in particular to a diagnosis method, device, equipment and storage medium for a fault of a combination meter. Background technique [0002] In recent years, with the development of electronic technology, the intelligent level of automobiles has become higher and higher, and large-screen full LCD instruments have been widely used. It will directly affect the user's evaluation of the model and purchase intention. Therefore, when a problem occurs in the combination meter, it is necessary to analyze the problem and solve the problem in time. When the combination meter is running, record the abnormal information that occurs in the combination meter. The abnormal information is compiled according to the design rule, and finally the compiled abnormal code is compared with the preset diagnostic code, and the abnormal information is located according to the comparison resul...
