BATTERY VOLTAGE LOW System voltage below 11 volts. Handle commands disabled.
IO BOARD FAULT n CPU not communicating with I/O board n,
where:
1 – first I/O board after the CPU
2 – second I/O board after the CPU
4 – third I/O board after the CPU
8 – fourth I/O board after the CPU
Failure of more than one board is
indicated by an n value that is the sum of
the n values associated with each board
(I.e. if n=6, the second and third I/O
boards after the CPU may have failed)
Check for loose or damaged I/O board.
Reposition and reconnect the boards in the
circuit to see if the problem moves with the
location. If the indicated fault code n does not
change, the problem is most likely in the
motherboard or the CPU board.
See procedures in Folio 2238 at the end of this
section.
