the inducement to troubleshoot problems. Factory
passwords are required to activate this override.
Once the override is activated, navigation to other
electronic service tool functions is possible. Usually,
the “Engine Emissions Operator Inducement Service

the service tests performed in the applicable

inducement. The “Engine Emissions Operator
Inducement Service Mode Override” is located in the
“Diagnostic Tests” , “System Troubleshooting
Section” of the engine ECM.
