Selective Catalytic Reduction Warning System
If a fault condition exists for the entire duration of
inducement level 1, the strategy advances to
inducement level 2. The check engine lamp and the
emissions malfunction indicator lamp will illuminate
and flash slowly. If the inducement is a result of a
category 1 fault, then a level 2 inducement will occur.
The level 2 inducement will occur for a duration of 18
hours for first occurrence. For repeat occurrence, a
category 1 level 2 inducement fault will occur for a
duration of 108 minutes.
If the inducement is a result of a category 2 fault, then
a level 2 inducement will occur for a duration of 5
hours. For repeat occurrence, a category 2 level 2
inducement fault will occur for a duration of 1 hour.

Reduced Time
If configured to "Reduced Time" and a fault condition
exists for the entire duration of inducement level 2,
the strategy advances to inducement level 3.
Inducement level 3 has the same actions for all
categories. The check engine lamp and emissions
malfunction indicator lamp will flash at a fast rate. A
red stop lamp will also illuminate solid. The engine
will have a 100% derate and be limited to 1000 rpm
or low idle, whichever is greater. If, the final
inducement action in the electronic service tool is set
to "Idle Down" , then engine will continue to idle at
derated condition. If set to "Shutdown" , engine will
shut down after 5 minutes. A key cycle will allow safe
harbor mode to initiate. Safe harbor is allowed up to
three times. After safe harbor, the engine will be in
level 3 final inducement. If set to "Shutdown" , the
engine may be restarted, but will only run for 5
minutes at derated condition before shutting down
again. This action will continue until the issue is
resolved.
Note: Contact your Perkins distributor for repairs if a
fault occurs.
Inducement Strategy for DEF Level
(Worldwide)
Illustration 59

If the DEF level falls below 20%, an amber indicator
will illuminate next to the DEF level gauge on the
dash. To avoid inducements, turn the key to the OFF
and add DEF to the DEF tank.
Illustration 60
If the DEF level falls below 13.5%, a level 1
inducement event will occur. The check engine lamp
and the emissions malfunction indicator lamp will
illuminate. The amber indicator next to the DEF level
gauge on the dash will remain lit.
