The sequence for the flash code is started by moving
the keyswitch to "Off" and then moving the keyswitch
to "On" twice within a period of three seconds. After
a delay of 2 seconds, the "Shutdown" lamp will flash
once for a period of half a second. This sequence
indicates the start of the active fault codes. After
a further delay of 2 seconds, the "Warning" lamp
will flash repeatedly in order to indicate the active
diagnostic codes. Each flash will be on for half a
second and off for 300 milliseconds. The "Warning"
lamp will remain off for 2 seconds between each digit
of a code. If there is more than one active diagnostic
code, the "Shutdown" lamp will go off for 2 seconds.
The lamp will then come on for a period of half a
second. The "Warning" lamp will go off for a period of
2 seconds before starting the next code. If there are
no active diagnostic codes, the "Warning" lamp will
flash the code "551". Refer to Troubleshooting Guide,
"No Diagnostic Code Detected".
As an example, an active diagnostic code of "21" is
indicated by the "Warning" lamp coming on for 500
ms, then off for 300 ms, then on for 500 ms, then off
for 2000 ms, then on for 500 ms and then off.

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 then the "551"
code should be flashed again.
After all of the codes have been displayed, the
"Shutdown" lamp will flash 3 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 flash code that related to the
diagnostic code.
Note: Flash codes are always sent in ascending
numerical order.
