Abstract

The invention discloses a tester for an automotive electronic control system and a testing method thereof. The tester comprises a testing box including a computer, a control module, M first interface terminals, M second interface terminals, M electrical lines, N test terminals and a relay matrix. All electrical lines are connected with the corresponding first interface terminals and second interface terminals. The control module controls connection or disconnection of the electrical lines. The relay matrix includes M*N third relays. A plurality of circuit diagrams and databases corresponding to the circuit diagrams are stored into the computer; the circuit diagrams have ECU pin data; and the databases are databases of correspondence relations between the ECU pins and the testing terminals. According to the invention, definition of the testing terminals on the testing panel can be replaced automatically according to the ECU pin data of the selected specific circuit diagrams; and different anode and cathode joint groups are replaced in a cooperative mode. Therefore, wide application of the tester and method to different automobile manufacturers, different automobiles, and different electrical control systems can be realized.

Description

technical field [0001] This application relates to the field of testing of automotive electronic control systems. Background technique [0002] When diagnosing the automotive electronic control system (hereinafter referred to as the electronic control system), it is first necessary to use a fault diagnosis instrument to read the fault codes and other information stored in the electronic control unit (hereinafter referred to as ECU), and then it is necessary to use a test box. The specific device detects the specific wiring harness, components and ECU. One end of this test box is a set of female connectors and a set of male connectors. The female connectors are used to connect to the ECU of the electronic control system, and the male connectors are used to connect to the automotive wiring harness. The inner pins of the female connector and the inner pins of the male connector correspond to each other and are connected, so as to ensure the electrical communication between the...
