Abstract: In order to effectively improve the school's new energy automotive professional group teachers, students on the automotive engine electronic control system fault repair practice level, this article takes Volkswagen Bora as the carrier, and teachers and students jointly research and design a set of engine electronic control system teaching fault setting boxes to facilitate teachers' practical teaching and students' skill competition training. This fault setting box can flexibly set circuit breaks, short circuits, swapping, virtual connections, etc., simulating the real fault repair process. Its design process is as follows: firstly, based on the Volkswagen Bora circuit diagram, sort out the engine computer board harness; secondly, design the size of the fault setting box and the layout of the pins; then, weld the wire harness onto the computer board and check its conductivity after the wire harness welding is completed; finally, the teaching vehicle with a fault setting box is functionally validated against the original vehicle to verify the effectiveness of the designed teaching vehicle fault setting box.
