Troubleshooting Section
8. If necessary, use the electronic service tool to clear
the rating interlock. To clear the rating interlock,
enter the factory password when the electronic
service tool is fi rst connected. Activating the “Test
ECM” mode will also clear the rating interlock.
9. Use the electronic service tool to program the
parameters. Perform the following procedure.
a. If the “Copy Con fi guration” procedure was
successful, use the “Copy Con
fi guration, ECM
Replacement” function to load the con fi guration
fi le into the ECM.
Note: During the following procedure, Factory
Passwords may be required.
b. If the “Copy Con fi guration” procedure failed,
con fi gure the parameters individually. The
parameters should match the parameters from
step 3.
Perform the “Fuel System Veri
fi cation Test”.
10. Check for logged diagnostic codes. Factory
passwords are required to clear Logged Events.

Self-Diagnostics
The Electronic Control Module (ECM) has the ability
to detect problems with the electronic system and
with engine operation. When a problem is detected, a
code is generated. An alarm may also be generated.
There are two types of codes:
•
Diagnostic
•
Event
Diagnostic Code – When a problem with the
electronic system is detected, the ECM generates a
diagnostic code. This indicates the speci fi c problem
with the circuitry.
Diagnostic codes can have two different states:
•
Active
•
Logged
Active Code – An active diagnostic code indicates
that an active problem has been detected by the
control system. Active codes require immediate
attention. Always service active codes prior to
servicing logged codes.
Logged Code – Every generated code is stored
in the permanent memory of the ECM. The codes
are logged for 100 operating hours unless a code is
cleared by use of the electronic service tool.
Event Code – An event code is generated by the
detection of an abnormal engine operating condition.
For example, an event code will be generated if the
oil pressure is too low. In this case, the event code
indicates the symptom of a problem.
Logged codes may not indicate that a repair is
needed. The problem may have been temporary. The
problem may have been resolved since the logging
of the code. If the system is powered, it is possible
to generate an active diagnostic code whenever a
component is disconnected. When the component is
reconnected, the code is no longer active. Logged
codes may be useful to help troubleshoot intermittent
problems. Logged codes can also be used to review
the performance of the engine and the electronic
system.

Sensors and Electrical
Connectors
The Electronic Control Module (ECM) and the
sensors are located on the left side of the engine.
