Are all the keypads waterfalling or just the one reporting the error?
Generally if one bad keypad is shutting down the system, I'd diagnose it by removing it from the wall and disconnecting it from the wiring harness. If the keypad was truly the fault, removing it from the link should restore functionality to the rest of the keypads.
