Toyota Corolla E180 smart junction box pinout diagram?

Yep, I agree, here is the wiring for the power distribution box under the hood, I assume this is what you mean by SJB which VW does not reference. They do not give us a pinout for this, sorry. I will email them to you as well. Check out the images (below). Let us know how it goes

Thank you very much! This is a circuit diagram though, not a pinout map. Meanwhile I managed to put my hands on a partial map, along with a service manual smuggled out from some Toyota service. It's a heap of HTML and Javascript mess though, and very difficult to use. It also doesn't reveal every pin. It does, however, describe the testing procedures, so I might be able to locate the problem after all.

Yep, we don't have pin outs for this particular car so I gave you what we had, hope you get it fixed, if you need any other help let us know.
