Selective Catalytic Reduction Warning System
• Inducement Categories The Inducements are
separated into categories. DEF Levels have
inducement fault codes separate from the other
inducement categories. DEF level inducements
are based on the DEF level, the other inducement
categories are based on escalating time. The
escalating time inducements will always have an
associated fault code along with the inducement
fault code. The associated fault is the root cause.
The escalating time inducement fault code is just
an indicator of what level of inducement the
engine is in. The escalating time inducement fault
code also indicates how much time remains until
the next level of inducement. There are three
inducement categories that will trigger an
escalating time inducement fault code.
Note: The associated codes for each of the
escalating time categories can be found in
Troubleshooting, SCR Warning System Problem.
• First Time When an escalating time inducement
fault code becomes active for the first time.
• Repeat occurrence When any escalating time
inducement fault code becomes active again
within 40 hours of the first occurrence. Engine
must run for 40 hours without tripping any
escalating time inducement fault before returning
back to first occurrence times.
• Safe Harbor Mode (Worldwide) Safe Harbor
Mode is a 20 minute engine run time period. Once
in level 3 inducement, the operator can perform a
key cycle and the engine will enter Safe Harbor
Mode. Safe Harbor Mode can only be
implemented once. Safe Harbor Mode is not
allowed for DEF level inducements with Worldwide
configuration.
