Technical Field

[0001] The utility model relates to the technical field of automobile product detection, in particular to an automobile control unit detection device. Background Art

[0002] With the rapid development of automotive electronic technology, the role of automotive control units (ECUs) in vehicles has become increasingly important, and the normal operation of their functions is directly related to the performance, safety and reliability of the vehicle. However, as a highly integrated electronic device, ECUs themselves may also fail, causing vehicle abnormalities or even accidents. Therefore, it is crucial to effectively detect and diagnose ECUs. Traditional ECU detection methods mainly rely on diagnostic interfaces (OBD) to read fault codes, but the amount of information is limited and it is difficult to accurately determine the cause of the fault. In addition, some new ECUs use complex encryption technology, which makes it difficult for traditional methods to effectively detect them.
