Hello. My name is ***** ***** I will be assisting you today. I see that you are looking for information on the ECM pinout. I can provide you the wiring diagram with this information. Just a moment, please.

Ask Your Own VW Question

Here is the information that you have requested. I am attaching the electrical information for the circuits the shows what pin 62 controls. I have highlighted the areas of concern. The pin controls the power supply relay and is also connected to fuse #37 in the fuse panel. The issue could just be the ECM, but the power supply relay and the fuse panel should also be inspected. I am thinking that the power supply relay or the ECM is the issue. The short version is what you should be inspecting, although, I have attached the complete information also.
