Use the electronic service tool to perform the
following activities for the monitoring system:
• Viewing parameters
• Parameter programming
• Set delay times
The default settings for the parameters are
programmed at the factory. To accommodate unique
applications and sites, some of the parameters may
be reprogrammed with the electronic service tool.
Use the electronic service tool to modify the
monitoring system parameters.
Note: Some parameters do not require a password in
order to be changed. Other parameters can be
changed with customer passwords. Certain
parameters are protected by factory passwords.
Some parameters cannot be changed. Some
applications do not allow any changes to the
programmable monitoring system. Parameters that
are protected by factory passwords can only be
changed by dealer personnel.
Viewing or Changing the Settings
of the Monitoring System
Use the following procedure in order to view the
parameter settings and/or change the parameter
settings:
1. Select the “Service/Monitoring System” screen on
the electronic service tool.
Note: Ensure that you select the correct ECM for the
parameters that are being changed before
continuing.
2. Highlight the desired parameter. Then click the
“Change” button in the lower left corner of the
screen.
The “Change Monitor System” screen will appear.
3. Change the “State” of the parameter.
4. Set the “Trip Point” and the “Delay Time” according
to the “Allowed Values” that are displayed in the
lower half of the screen.
5. Click the “OK” button.
If a password is required, the “Enter Passwords”
screen will appear. Enter the correct passwords
and then click the “OK” button.
Note: If a factory password is required, the “Enter
Factory Passwords” screen will appear. Refer to
Troubleshooting, “Factory Passwords” for information

Diagnostic Capabilities
Diagnostic Codes
The engines Electronic Control Module (ECM) can
monitor the circuitry between the ECM and the
engines components. The ECM can also monitor the
engines operating conditions. If the ECM detects a
problem, a code is generated.
There are two categories of codes:
• Diagnostic code
• Event code
Diagnostic Code – A diagnostic code indicates an
electrical problem such as a short circuit or an open
circuit in the engines wiring or in an electrical
component.
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. Generally, event
codes indicate abnormal operating conditions or
mechanical problems rather than electrical problems.
Codes can have two different states:
• Active
• Logged
Active Codes
An active code indicates that a problem is present.
Service the active code first. For the appropriate
troubleshooting procedure for a particular code, refer
to the following troubleshooting procedure:
