This invention provides an electrical fault detection device for an automotive body controller, relating to the technical field of electrical fault detection devices. It includes: a detection unit; a connection unit external to the detection unit; an external connection unit external to the detection unit; and an external display unit external to the detection unit. By configuring multiple flip-top connectors and corresponding detection wiring on an integrated board, the appropriate detection wiring can be flexibly replaced according to the connector specifications and pin definitions of different vehicle body controllers, eliminating the need for dedicated detection equipment for a single vehicle model. Simultaneously, the rotating connection structure between the flip-top connector and the energized guide rod, combined with the storage function of the flip-top slot, solves the problem that dedicated diagnostic equipment requires frequent replacement of appropriate wiring harnesses and connectors according to specific vehicle models during practical applications. This not only results in cumbersome operation and poor versatility but also further prolongs the fault diagnosis cycle.

The utility model belongs to the technical field of intelligent cards, in particular to a light-emitting diode (LED) intelligent card convenient to manufacture, which comprises an integrated circuit (IC) module and realizes high-precision positioning in the manufacturing process. By means of the design, errors and the defective product rate in the manufacturing process are reduced, and the production efficiency is remarkably improved. Meanwhile, the FPC board with the double-face circuit board design is adopted, the compact LED light-emitting module with the bonding pad spacing smaller than or equal to 0.5 mm and the flip chip structure is combined, the integration level of the circuit and the manufacturing fineness are further improved, different circle numbers and spacing are elaborately set through the FPC board LED antenna according to the capacitance condition so as to be matched with the working frequency of the IC module, interference on the IC module circuit is avoided, and the reliability of the IC module circuit is improved. The electromagnetic compatibility of the product is further improved through the frequency separation design. Besides, the FPC board with the four-layer structure and the LED intelligent card INLAY are bonded in a hot-pressing mode, so that stable installation of each component in the plastic base material is ensured, and the overall flatness and durability of the product are improved.
