Abstract
This paper describes a framework of a system for examining OBD scanners, presenting that system's functionality and how to implement it in practice. There is a brief discussion of software designed for the Microsoft Windows environment to control and visualise the testing process. The paper also discusses additional software modules designed to examine specific properties of the OBD-equipped devices that are manufactured for the German market. These include examining the technical status of the two-state and broadband oxygen sensors based on analysing logged the temporal sequence of momentary current or voltage values.
