Active Codes:
Codes that are currently
keeping the Check Engine or Stop Engine
telltale light illuminated. Active codes are flashed
via the Stop Engine Light when checked with the
stop-engine-override switch.
Inactive Codes:
These are all the codes
logged in the CPC, which have previously
occurred, (whether or not they are currently
turning on the Stop or Check Engine Light).
Inactive codes are flashed via the Check Engine
telltale light when checked with the stop-engine-
override switch.
In most instances, only the DDR can provide the
information necessary for a quick diagnosis of
the problem. If you just need to read out codes,
however, and do not have a DDR available, the
following procedure will let you read out codes.
Make sure the rear-starting switch (located in
the engine compartment) is in the normal
position. With the ignition ON, the engine idling
or engine shut-off, momentarily depress the
Stop Engine Override (SEO) switch. Active
codes will be flashed on the stop engine telltale,
followed by the inactive codes being flashed on
the check-engine telltale panel. The cycle
repeats itself until the operator depresses the
stop engine override switch again.
Flashing codes provide a four digit number.
Each fault code is flashed twice in order to help
with counting the flashes. If there are no active
faults or if there are no inactive faults the
number “3” is flashed once followed by an ~3s
delay.
FIGURE 19: FLASHING FAULTS CODES
Refer to DDEC Troubleshooting Manual 6SE567
for more information and SAE codes.
NOTE
Active codes are flashed in ascending
numerical flash code order. Inactive codes are
flashed in most recent to least recent order.
NOTE
Fault codes can only be cleared using the
DDR.
NOTE
The listed codes may not be used in all
applications. A default value in the normal
operating range is used by the MCM to
provide for engine operation if a sensor failure
is present.
