Technical Field

[0001] The present invention relates to a rapid diagnostic device for the harness circuit of an automatic transmission assembly, belonging to the technical field of automotive automatic transmission inspection. Background Art

[0002] In the field of automotive automatic transmission assembly testing, the harness circuit, as a key component for transmitting control signals and power supply, the stability of its electrical performance and connection status directly affects the overall operation efficiency of the transmission.

[0003] In the prior art, although there have been detection methods using a multimeter to measure voltage and resistance parameters, such methods have inherent defects. On the one hand, the point-by-point measurement method leads to a long detection time, making it difficult to meet the requirements of large-scale production; on the other hand, the detection process has a high dependence on the professional skills of the operator, increasing the risk of errors caused by human factors.

[0004] With the rapid development of automotive electronic technology, the complexity of the automatic transmission harness circuit has increased exponentially. The traditional detection methods have shown inadequacy when dealing with new circuit architectures such as high-density wiring, multi-node networks, and composite signal transmission.

[0005] Furthermore, for the diagnosis of the harness circuit in the automatic transmission assembly test environment, it is necessary to consider the three dimensions of operation safety, detection efficiency, and result accuracy. The traditional detection methods often require partial disassembly of the vehicle or large-scale harness disassembly, which not only increases the operation difficulty but also may cause the risk of physical damage to the object under test.

[0006] Therefore, developing a harness circuit automatic diagnostic device with fast response ability, high-precision diagnostic characteristics, and safety operation guarantee has become a key technical requirement for improving the test efficiency of automatic transmission assemblies.

[0015] Further, the visual diagnosis module is an LED combination indicator light, and the LED combination indicator light can automatically analyze the detection result and display the name of the faulty circuit.

[0016] Further, the number of the LED combination indicator lights matches the number of the harness circuits to be detected, and each LED combination indicator light corresponds to a specific harness circuit.

[0017] Further, the lithium battery is a low-voltage lithium battery, and the voltage of the low-voltage lithium battery is 20V.
