4. DDEC V DIAGNOSTIC CODES
4.1 READING DIAGNOSTIC CODES -
FLASHING LIGHT METHOD:
DDEC V makes use of two types of codes:
Active and inactive. The difference between the
two types of codes is as follows:
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 ECM (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
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. A code
"43" consists of four flashes, followed by a short
pause, then three flashes in quick succession.
Refer to DDEC Troubleshooting Manual 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 ECM to provide
for engine operation if a sensor failure is
present.
