Ya, I realize that, but I wouldn't want anyone to ground out that pin for testing purpose's, until I could see (inside the module ).
That may not be the point of ground, as it's not indicated as a ground point,
just sayin. Wouldn't want to unknowingly damage an chip inside.
Thats just me...lol
My next step, when weather permits, will be to check all grounds and power
to the module's, open up the module and check for corrosion etc.
I'll also see what makes it 'tick" what type of "chips" are inside and can they be replaced individually.
After that, I'll have the codes read. CTC over here will read them for 45$.
JS, here's a few on ebay to give you an idea.

Removing the relay from its socket and using some clip leads or other jumpers to connect the coil power and contact leads, and then grounding the coil ground to chassis ground would keep the module out of the loop.
After this is done, and the wires from the relay socket to the module verified to be good, (no shorts or grounds), then the problem is isolated to the module not doing its job.
