Automobile audio head unit diagnosis method and system based on engineering mode encryption

Abstract

The application discloses a car audio car machine diagnosis method and system based on engineering mode encryption, and the method comprises the following steps: a manufacturer server generates a user account and a user password according to a user account application request instruction, and sends the user account and the user password to a mobile terminal through a cloud server; a mobile terminal scans a two-dimensional code on a car audio car machine, and the two-dimensional code is generated by the car audio car machine according to a unique machine identification code; the mobile terminal sends the two-dimensional code, the user account and the user password to the cloud server together, the cloud server identifies the two-dimensional code to obtain the unique machine identification code; the cloud server generates an engineering mode password according to the unique machine identification code, the user account and the user password; the cloud server sends the generated engineering mode password to the car audio car machine and the mobile terminal respectively, and the car audio car machine uploads fault description to the cloud server according to a check result of the engineering mode password.
