Timing of the flash codes
After all of the active diagnostic codes have been
displayed, the "Shutdown" lamp will go off for 2
seconds. The "Shutdown" lamp will flash twice in
order to indicate the start of the sequence that will
display the logged diagnostic codes. The process for
flashing logged diagnostic codes is identical to the
process for flashing active diagnostic codes.
Note: If there are no logged codes, the "551" code
should be flashed again.
After all of the codes have been displayed, the
"Shutdown" lamp will flash three times in order to
indicate that there are no further codes. Cycling the
keyswitch twice within a period of 3 seconds will start
the process again. All codes will be displayed in
ascending numerical order.
Refer to the Troubleshooting Guide, "Diagnostic
Codes" for the diagnostic code that relates to the
flash code.
Note: Flash codes are always sent in ascending
numerical order.
