Providing more context on where you encountered the code will help narrow down its exact application.
: A video of a robotic arm repeatedly opening a door handle or a "shaker table" test for dashboard rattles.
The subject appears to be a technical code or part number, most likely associated with General Motors (GM) engineering standards or automotive component specifications .
: Standards ensure that parts like seatbelt retractors or airbag housings won't fail under extreme temperatures.
: In a digital context, .avi is a video file format. If this subject appeared as a file name, it likely refers to a recorded validation test . Engineers often record high-speed footage of crash tests, suspension cycles, or component failures to analyze how a part behaves under stress. Why These Specifications Matter
If you are looking at a file named GM_D4179.avi , you are likely viewing . This could be:
: These codes help technicians track the evolution of a part. If "avi" footage shows a hairline fracture during a 100,000-mile simulation, the specification is revised to improve the part's longevity. Interpreting the "avi" Component
