Introduction

GB/T 45784 mainly involves the technical requirements of the standard interface for agricultural vehicle maintenance information, including agricultural vehicle maintenance information Overall requirements for standard interfaces and hardware and software requirements for on-board diagnostics.

GB/T 45784 is intended to consist of two parts.

--- Part 1: Web-based user interface requirements. The purpose is to specify the general requirements of the standard interface for agricultural vehicle maintenance information.

Requirements, principles, use case definitions, technical requirements.

--- Part 2: On-board diagnostics. The purpose is to specify the minimum hardware and software requirements for on-board diagnostics and provide the hardware of the diagnostic tool and software specifications.

Standard interface for agricultural vehicle maintenance information Part 2: On-board diagnostics

1 Scope

This document specifies the minimum hardware and software requirements for vehicle maintenance by describing the minimum hardware and software requirements, including software flash, calibration, and configuration requirements after repair.

This document provides the hardware and software specifications for the diagnostic tool.

This document does not apply to conversion kits as these are not an integral part of the vehicle.
