I have an idea to build a diagnostic tool for the many switches and sensors in the top operation. If anybody has a known bad PTCM, I will be most happy to buy it and pay shipping.

I want to remove the connector of the existing board and start building a diagnostic tool considering most of us do not have access to a proper scanner tool.

I counted 5 travel sensors and 8 status sensors. They did leave out the rain sensor IMHO.
