18 Failure classification concept (concept) Emissions related malfunctions would be classified in 4 classes Class A. OTLs are exceeded. The MI is permanently ON. Class A Class B1 Class B1. OTLs are probably exceeded but there is a doubt. The MI is ON and turns OFF after [60]s If no repair is done within [xx] driving time, the MI is permanently ON Class B2. OTLS are not exceeded. The MI is ON and turns OFF after [60]s Class C. emission limits are not exceeded. The MI turns OFF when the truck is moving Class B2 Class C OTL TA limit
