Lost all programming on the original board.

Used our tool, was able to get it functioning, but Fire Service doesn’t work correctly. Was told that we would need a new board and chipset to correct.

Ordered a new board and chipset, programmed for a 3 stop and reset selector top to bottom.

Car will only run between 1 & 2. Ignores 3rd landing altogether.

Any help would be greatly appreciated.

A quick note, we have put the original board back in, reprogrammed and it runs fine to all landings but still has Fire Service problem.

Only issue is with the new boards.
