CBM 20A error

[Jeffetw]

I attempted to connect a Option Box VP with an attached FCV-14AH to my CBM-20A, and it worked. Then the CBM started throwing the following error: "SUBC leak is detected. 008C. Code: 0x548C". The power bar would turn red, as would the power bar on the "offending" pump, which is running fine, no leak. The pump itself reads "CBM20A error". Tried to just plug through by clearing out the errors, but they would return and hit each of the three pumps in no particular order.

Disconnected the Option Box VP, the errors ceased. I feel like I'm running into some sort of address issue but I'm at a loss as to what to do. Any thoughts?

Thanks for the help!

Solved the issue. The leak sensor on the option box vp was faulty. Replaced it and the system now works fine.
