Operator Level Inducement
Inducements are engine derates, vehicle speed limits, or other actions intended to prompt the operator to repair or maintain the emissions control system.
Inducement strategies are control actions required by EPA/ARB Tier 4 final and EU Stage IV regulations to ensure prompt correction of various failures in the engine NOx emissions control system. The EPA/ARB require actions to limit engine performance and define required indications such as visual alarms including lamps and messages, as well as audible alarms, while the control actions are imposed.
Refer to Systems Operation, "DEF Dosing Control System" for additional information on inducement configuration options and inducement actions.
Engine Emissions Operator Inducement Service Mode Override
This override allows the service technician to disable the inducement to troubleshoot problems. Factory passwords are required to activate this override. Once the override is activated, it is possible to navigate to other Cat® Electronic Technician (ET) functions. Usually the "Engine Emissions Operator Inducement Service Mode Override" will not need to be activated because the service tests performed in the applicable troubleshooting procedure will automatically reset the inducement. The "Engine Emissions Operator Inducement Service Mode Override" is located in the "Diagnostic Tests", "System Troubleshooting Section" of the engine ECM.
