If the DEF level is below 7.5%, a level 2 inducement
event will occur. The check engine lamp and the
emissions malfunction indicator lamp will illuminate
and flash slowly. The amber indicator next to the DEF
level gauge on the dash will remain lit. If the ECM is
configured to "Reduced Performance" and the DEF
level has reached 1%, the machine will be limited to
75% torque.

If the ECM is configured to "Reduced Performance"
and the DEF tank has been emptied of all DEF, the
engine will be in a level 3 final inducement. If the
ECM is configured to "Reduced Time" and the DEF
level is 3%, the engine will be in a level 3 final
inducement. The check engine lamp and the
emissions malfunction indicator lamp will flash at a
fast rate and a red stop lamp will illuminate solid. The
engine will be taken to low idle or will be shut down.
Once shut down, the engine can be restarted for 5
minute periods at reduced speed and torque. If set to
idle, the engine will idle indefinitely at reduced torque.
The amber indicator next to the DEF level gauge on
the dash will remain lit.
Note: Turn the key to the OFF and add DEF to the
DEF tank to reset the DEF level inducement.

The check engine and emissions malfunction
indicator lamp will illuminate for a level 1 inducement-
related fault. There are three inducement categories.
If the inducement is a result of a category 1 fault, then
a level 1 inducement will occur for a duration of 2.5
hours for first occurrence. For repeat occurrence, a
category 1 level 1 inducement fault will occur for a
duration of 5 minutes.
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 category 2,
level 1 inducement faults.
If the inducement is a result of a category 3 fault, then
a level 1 inducement will occur for a duration of 36
hours. There is no repeat occurrence for category 3,
level 1 inducement faults.
Reduced Time The check engine and emissions
malfunction indicator lamp will illuminate for a level 1
inducement-related fault. There are three inducement
g03676210
categories. If the inducement is a result of a category
1 fault, then a level 1 inducement will occur for a
duration of 2.5 hours for first occurrence. For repeat
occurrence, a category 1 level 1 inducement fault will
occur for a duration of 5 minutes.
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 category 2,
level 1 inducement faults.
If the inducement is a result of a category 3 fault, then
a level 1 inducement will occur for a duration of 18
hours. There is no repeat occurrence for category 3,
level 1 inducement faults.
