aftrtrtmntsroprtrindmntsvrtj1939 - SPN 5246

Aftertreatment SCR Operator Inducement Severity

Severity status of the operator inducement system for anomalies with the SCR (Selective Catalytic Reduction) system, such as tampering, low DEF quality, and DEF tank level. Higher numerical levels indicate more severe levels of inducement. Level 1 is the least severe. These are the possible values of aftrtrtmntsroprtrindmntsvrtj1939 and their meanings:

000b : 0 : Non-Active (Driver Warning, Low-Level Inducement, and Severe Inducement are all Non-Active)

001b : 1 : Inducement Level 1 … EPA defined SCR Inducement - DEF Warning ...................... FMI 15 …Euro VI - Driver Warning System Active ................................... FMI 15 …Off Highway (Tier4) - DEF Warning…….................................... FMI 15

010b : 2 : Inducement Level 2 … DEF Warning, second level (optional) ...................................... FMI 15 ... Euro VI - Low-Level Inducement Enabled ................................. FMI 15 …Off Highway (Tier4) - DEF Warning, second level.................... FMI 15

011b : 3 : Inducement Level 3 … EPA defined SCR Inducement - Engine Derate ..................... FMI 16 ... Euro VI - Low-Level Inducement Active .................................... FMI 16 …Off Highway (Tier4) - Low-Level Inducement Active................. FMI 16

100b : 4 : Inducement Level 4 ... Severe Inducement Pre-Trigger (optional) ….…….................. FMI 16 ... Euro VI - Severe Inducement Enabled ...................................... FMI 16 …Off Highway (Tier4) - Severe Inducement Enabled.................. FMI 16

101b : 5 : Inducement Level 5 ... EPA defined SCR Inducement - Severe Inducement …........ FMI 0 ... Euro VI - Severe Inducement Active ......................................... FMI 0 …Off Highway (Tier4) - Final Inducement Enabled...................... FMI 0

110b : 6 : Temporary Override of Inducement - The SCR inducement has been temporarily interrupted.

Reference Euro VI implementing regulation Annex XIII, Appendix 5, section 3.1.(b), 3.1.(c), and 3.1.(d) for more information regarding Euro VI implementations. Reference EU directive 97/68/EC amendment (2012/46/EU), EPA webinar nrci-scr-web-conf.2011-07-25, and JMLIT "Technical Guidelines for Urea Selective Catalytic Reduction System" Kokujikan 132-3, Feb.16, 2012 for Off Highway (Tier4) implementations. JMLIT - Japan Ministry Of Land, Infrastructure, Transport and Tourism Note: SPN 5246 is similar to SPN 5826. SPN 5246 is intended to be used to indicate the severity status of the operator inducement system for anomalies with the SCR system only, whereas SPN 5826 is intended to be used to indicate the severity status of the operator inducement system for anomalies with the SCR and EGR systems. Thus, SPN 5246 is a subset of SPN 5826, and if both are utilized, will match only under certain conditions.
