Well those all look appropriate. Is there an EMS in play by chance? I’d still like to see the M-1-2-1-3 set it to 5-1 and have someone push the hall button and see if you’re seeing the input.
Could wire in an RS board with buttons in the MR also.
I cannot think of anything else as to why the bottom hall button would function but not the rest. Especially if swapping the IO board fixed it.
When I swapped the IO baord it still had the GECB attached. I was worried that something would be messed up (like tac32 and UIT is coded per car). We just got the IO board back and they are saying that NO ISSUES FOUND wiht the IO board!
I checked those Addresses on the handheld and everyhting matches the job perfectly, and even checked against the other car and everyhting is the exact same.
Not sure where to go from here other then getting a new GECB board.
