Scr aftertreatment system maintenance inducement method

A system, comprising:

• an internal combustion engine including an exhaust system for receiving an exhaust gas produced by the internal combustion engine;
• a selective catalytic reduction (SCR) aftertreatment system connected to the exhaust system for treating nitrous oxide emissions in the exhaust gas;
• a diesel exhaust fluid (DEF) tank connected to the exhaust system to provide DEF to the SCR aftertreatment system;
• at least one of:
• a DEF level indicator configured to detect a level of DEF in the DEF tank;
• a DEF quality indicator configured to detect a quality of the DEF;
• an SCR aftertreatment system indicator configured to detect an SCR system malfunction;
• and
• a controller configured to determine an inducement signal value in response to the at least one of the DEF level indicator, the DEF quality indicator, and the SCR aftertreatment system indicator obtaining a threshold value, the controller further being configured to derate the engine in response to the inducement signal value.
