The repeat offense of NCD(NOx Control Diagnostic system) inducement is different dependent on
Emission regulation. Refer to the below example case for better understanding.
* EU Stage5
If DEF quality or Dosing Interrupt faults are confirmed up to warning/Level1, and faults are occurred
again within 40 hours, the fault counter is setting to last value when repeat offense is enabled.
Graph 8-1. EU Stage5 DEF quality or Dosing interrupt Repeat offense at Warning/Level
If DEF quality or Dosing Interrupt faults are confirmed up to Severe level, and faults are occurred
again within 40 hours, the fault counter is changed before 90%(18hrs) of counter value of Severe
level. It means that the fault level is changed to Level1 and Severe level will be reached within 2hrs.

The repeat offense of Impeded EGR or Tampering faults are only differed the NCD inducement
counter(time), and the operation is same to DEF quality or Dosing interrupt fault
If Impeded EGR or Tampering faults are confirmed up to warning/Level1, and faults are occurred
again within 40 hours, the fault counter is setting to last value when repeat offense is enabled.
Graph 8-3. EU Stage5 Impeded EGR or Tampering Repeat offense at Warning/Level
If Impeded EGR or Tampering faults are confirmed up to Severe level, and faults are occurred again
within 40 hours, the fault counter is changed before 95%(95hrs) of counter value of Severe level. It
means that the fault level is changed to Level1 and Severe level will be reached within 5hrs.
