Abstract

The invention provides an integrated automotive diagnostic instrument and a diagnosing method thereof, wherein the integrated automotive diagnostic instrument comprises a PC, an electric control unit, a diagnosis adapter and a diagnosis server. The integrated automotive diagnostic instrument has advantages of relatively high versatility and relatively low cost. Furthermore diagnosis efficiency and diagnosis accuracy of maintenance service personnel are improved. The diagnosing method comprises the steps of a first step, connecting the PC with an electric control unit and establishing communication connection between the PC and the electric control unit, and simultaneously initializing the diagnosis adapter; a second step, selecting a diagnosing function; a third function, performing function testing; and a fourth step, displaying a diagnosing result. The integrated automotive diagnostic instrument and the diagnosing method have advantages of realizing function integration and greatly improving versatility of diagnosing software.

Description

technical field [0001] The invention relates to a vehicle diagnostic instrument, in particular to an integrated vehicle diagnostic instrument and a diagnostic method thereof. Background technique [0002] As automotive technology continues to evolve, modern vehicles increasingly use electronic control units (ECUs) to control vehicle activities. On the one hand, in order to improve the competitiveness of the whole vehicle, most of the automobile manufacturers will choose powerful electronic control units, and the complexity of the electronic control units will also increase; ECUs produced by different manufacturers, resulting in ECUs from multiple manufacturers being loaded on the same vehicle. [0003] With the increase of the number of electronic control units on the vehicle, the probability of failure of the automotive circuit with the electronic control unit as the core also increases, and it is more difficult to troubleshoot the electronic control unit; for this reason,...
