Abstract
A system and method of inducing proper operation of a diesel engine exhaust after-treatment system employing SCR technology monitors components to detect a fault condition representing one of a DEF level fault, a DEF quality fault, and a tampering fault, activates a trigger event indicator in response to detecting the fault condition. The trigger event indicator provides an indicium to an operator of the presence of the fault condition. The system and method also activates an inducement event indicator in response to activating the trigger event indicator. The inducement event indicator provides an indicium to the operator that the engine will be shut down if the fault condition is not addressed within a predetermined time period. The system and method causes shutdown of the engine when the fault condition is not addressed within the predetermined time period.
