The multi function lamp will flash a two-digit code in a
given sequence in order to show the flash code
diagnostic massage. By counting the number of
flashes in a given sequence you can determine the
flash code.
After the flash code as finished, the flash code
sequence will continual to be repeated. If a second
flash code has been activated, then the system will
repeat both codes in the given sequence.
Four short flashes will indicate a flash code of 04.
Three long flashes of one second each followed by
one short flash will indicate a flash code of 31.
