Flash Codes
The "Flash Code" feature is used to flash the two digit
code of all active diagnostic and event codes. Refer
to the Troubleshooting Guide, "Diagnostic Codes" for
the flash code that is related to the diagnostic code
or an event.
When a diagnostic code or an event code is active
or logged, the diagnostic lamp will flash repeatedly in
order to indicate the codes.
Each flash will be on for half a second and off for 300
milliseconds. The "Diagnostic" lamp will remain off for
two seconds between each digit of a code. If there
is more than one diagnostic code, the "Diagnostic"
lamp will go off for five seconds. The lamp will then
flash in order to indicate the next code.
As an example, an active diagnostic code of "21" is
indicated by the "Diagnostic" 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.
Illustration 4
Once all codes have been flashed, the "Diagnostic"
lamp will go off for a period of 15 seconds before
starting the sequence again.

and Derate)
Flashing On

Shutdown
Flashing Off
If the derate lamp comes on
during engine operation, and
the diagnostic lamp is flashing,
the lamps indicate that an active
diagnostic code (an electrical fault)
is present. The diagnostic code is
serious enough to cause an engine
derate.
If the shutdown lamp comes on
during engine operation, and the
diagnostic lamp is flashing, this
indicates that an active diagnostic
code (an electrical fault) is present.
The diagnostic code is serious
enough to cause the engine to
shutdown.
Note: Flash codes are always sent in ascending
numerical order.
