I have an early 90s relay logic each hydro with fires service phase 2 issue. Not sure if unit has always been this way or if it is a problem that has occurred recently. When put car on phase 2 everything works except for the door close button. It closes door when pressed but when release it doors stop where they are, don't reopen or close just stop.

Don’t know about this controller but Amtech H relay traction does something similar. State wrote it up but if you stare at the prints long enough that’s all it’s going to do. Can you share a print?

Not the best pictures of the prints can get some better ones tomorrow
