I took out the ISM. I’ll be honest I don’t know how to read electrical diagrams all the way, let alone test them. But I did find a couple wet connections. I found this picture online so that I can pin point what areas were wet. Z11B3 and Z11B5.

I think this could very well be the problem.

Here is a google photo link of the pictures: https://photos.app.goo.gl/x6UbAFws1Ph5p24j6
