Reduced Performance If a fault condition exists for
the entire duration of inducement level 1, the strategy
advances to inducement level 2. The check engine
and emissions malfunction indicator lamp will
illuminate and flash slowly for a level 2 inducement-
related fault. The engine will have a 50% derate. If
the inducement is a result of a category 1 fault, then a
level 2 inducement will occur for a duration of 70
minutes for first occurrence. For repeat occurrence, a
category 1 level 2 inducement fault will occur for a
duration of 5 minutes.
If the inducement is a result of a category 2 fault, then
a level 2 inducement will occur for a duration of 10
hours. For repeat occurrence, a category 2 level 2
inducement fault will occur for a duration of 2 hours.
If the inducement is a result of a category 3 fault, then
a level 2 inducement will occur for a duration of 64
hours. For repeat occurrence, a category 3 level 2
inducement fault will occur for a duration of 5 hours.
Reduced Time
If a fault condition exists for the entire duration of
inducement level 1, the strategy advances to
inducement level 2. The check engine and emissions
malfunction indicator lamp will illuminate and flash
slowly for a level 2 inducement-related fault. If the
inducement is a result of a category 1 fault, then a
level 2 inducement will occur for a duration of 70
minutes for first occurrence. For repeat occurrence, a
category 1 level 2 inducement fault will occur for a
duration of 5 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.
If the inducement is a result of a category 3 fault, then
a level 2 inducement will occur for a duration of 18
hours. For repeat occurrence, a category 3 level 2
inducement fault will occur for a duration of 108
minutes.

If 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
the emissions malfunction indicator lamp will flash at
a fast rate. A red stop lamp will 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" , the engine
will shut down after 5 minutes. A key cycle will allow
safe harbor mode to initiate. Safe harbor is only
allowed once. 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.
