Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, a structural diagram of a vehicle fault code clearing device of the present invention includes: a controller 1, a power supply (not shown in the figure), a bus interface 2, and a switch 3, and the power supply communicates with the The power supply terminal of the controller 1 is electrically connected, and the bus interface 2 is communicatively connected with the input and output terminals of the controller 1, wherein the controller 1 outputs a clear diagnosis instruction for clearing fault codes through a function addressing method.

[0024] Specifically, the switch 3 controls the on-off of the power supply and the controller 1 . When in use, connect the bus interface 2 to the vehicle, for example, connect to the diagnostic interface of the vehicle, and then turn on the switch 3, so that when the p...

Abstract

The invention discloses a vehicle fault code clearing device and system. The device comprises a controller, a power supply, a bus interface and a switch, the power supply is electrically connected with a power supply end of the controller through the switch, and the bus interface is in communication connection with an input and output end of the controller, wherein the controller outputs a clearing diagnosis instruction of clearing a fault code in a functional addressing mode. According to the vehicle fault code clearing device and system disclosed by the invention, the fault codes of all nodes are cleared in the functional addressing mode at one time. A user does not need to master the diagnosis knowledge. The operation is simple and fast. The user does not need to understand the diagnostic protocol in depth, so that the technical threshold is low, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field related to vehicles, in particular to a vehicle fault code clearing device and system. Background technique [0002] It is inevitable that the user will make some misoperations when using the vehicle, such as illegally cutting off the power, stepping on the accelerator and brake at the same time, unplugging the vehicle fuse before the vehicle is powered off, etc. These actions will cause the vehicle electronic control unit to generate a fault code. These fault codes may cause the indicator to light up, function degradation and other phenomena that may be misunderstood by the user. The user can only choose to go to the outlet for repair when this kind of failure occurs. [0003] The existing trouble code clearing tools need to diagnose the whole vehicle first, and then clear the trouble codes after the diagnosis result is obtained. However, the tools for diagnosing fault codes are relatively expensive, and...
