Hello, I would like to express a doubt that I have about the connection of instrument panels, in this case of the VAG group.
You see, I have several test cables, outside the vehicle, with which I manage to turn on the instrument panels and even diagnose by OBD. I usually do it, to check the illumination of the panel, segment tests, lights, needles etc...

But I have a doubt. In the panels, when they are in the car, when I turn on the lights, the spheres light up, that is, where the numbers of the revolutions and speed go.
Well, that "action", that is, turning on the lights, I cannot simulate it outside the car, my cables simulate the "contact" when turning the key.

My question is, how could I simulate that action to be able to see the complete illumination of the panels on my test bench at home? Thanks

Hello,
I have not understand your question too accurately but I think you want to check for example the engine light.
The most easier solution is to start an output test using a diagnostic tool.
What kind of instrument cluster you want to test more exactly?

Hello, and thanks for answering, the question is that the light tests with VAGCOM do not test the lights on the tachometer and speedometer dials... is there any way to test them?
