Reduced Time
If the ECM is configured to "Reduced Time" and the
DEF level is 0%, the engine will be in level 3
inducement. The check engine lamp and emissions
malfunction indicator lamp will illuminate and flash at
a fast rate. A red stop lamp will illuminate solid. The
DEF level gauge amber lamp will remain lit. 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 ET is set to "Idle Down" , then
the engine will continue to idle at derated condition. If
set to "Shutdown" , engine will shut down after 5
minutes. Safe Harbor Mode is allowed for three key
cycles. After Safe Harbor Mode is completed, the
engine will return to idle or shut down. If in shutdown
configuration, 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: Turn the key to the OFF and add DEF to the
DEF tank to reset the DEF level inducement.

Reduced Performance
The check engine and emissions malfunction
indicator lamp will illuminate for any inducement-
related fault. There are two inducement categories. If
the inducement is a result of a category 1 fault, then a
level 1 inducement will occur for a duration of 36
hours. If the inducement is a result of a category 2
fault, then a level 1 inducement will occur for a
duration of 10 hours. There is no repeat occurrence
for level 1 faults.
Reduced Time
The check engine and emissions malfunction
indicator lamp will illuminate for a level 1 inducement-
related fault. There are two inducement categories. If
the inducement is a result of a category 1 fault, then a
level 1 inducement will occur for a duration of 18
g03676127
hours. If the inducement is a result of a category 2
fault, then a level 1 inducement will occur for a
duration of 5 hours. There is no repeat occurrence for
level 1 faults.

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 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 occurs for a duration of 64
hours for first occurrence. For repeat occurrence, a
category 1 level 2 inducement fault will occur for a
duration of 5 hours.
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.
The engine will have a 50% derate. If the fault is not
corrected before the inducement duration ends, the
engine will become 100% derated. The engine will
also be limited to 1000 rpm or low idle, whichever is
greater. No further inducements will occur for
"Reduced Performance" configuration. Safe Harbor
Mode is allowed for three key cycles.
