•
DEF FLUID EMPTY: This pre-alarm displays when SPN 5245 has a value of 4 indicating that the
DEF tank level is low. The low condition is announced when the tank level is below 8%. When this
occurs and is not remedied, the engine ECU may enter a mode of inducement not to operate the
engine where some of the conditions in the pre-alarms descriptions below may occur.
•
DEF ENGINE DERATE: This pre-alarm displays when SPN 5246 has a value of 3, indicating the
Engine Derate level of inducement. This indicates that the engine is going into a reduced power mode
indicating the lowest level of inducement not to operate the engine when the EATS is not functioning
properly or out of DEF.
•
DEF PRESEVERE INDUCEMENT: This pre-alarm displays when SPN 5246 has a value of 4,
indicating the Pre-Severe Inducement level of inducement. This indicates that the engine has entered
the second highest level of inducement not to operate the engine when the EATS is not functioning
properly or the DEF level is low. The ECU will allow the engine to run for a maximum of 3 hours in
this condition. After expiration of the 3 hours, the engine will enter the severe inducement state and
cannot be restarted until the DEF level is raised above 14%.
•
DEF SEVERE INDUCEMENT: This pre-alarm displays when SPN 5246 has a value of 5, indicating
the Severe Inducement level of inducement. This indicates that the engine has entered the highest
level of inducement not to operate the engine when the EATS is not functioning properly or DEF level
is low. The ECU will allow the engine to run for a maximum of 3 hours in this condition. After
expiration of the 3 hours, the engine will enter the severe inducement state and cannot be restarted
until the DEF level is raised above 14%.
•
DEF INDUCEMENT OVERRIDE: This pre-alarm displays when SPN 5246 has a value of 6, indicating
temporary override of inducement. This indicates DEF inducement is temporarily overridden. The
engine may operate with reduced power, or for a limited time, after which time it may re-enter the
SEVERE INDUCEMENT state.
Exit Conditions for DEF Severe Inducement
•
First Restart: Return to 0% torque reduction in exit condition, until proper DEF level and quality
evaluation. If low level or poor DEF quality is detected during the next monitoring cycle, the severe
inducement will be active after the next restart. After the second restart, a service tool is required to
exit the severe inducement.
•
With Service Tool Clearing: Invoke 0% torque reduction with service tool clearing until proper DEF
level and quality evaluation. If low level or poor DEF quality is detected during the next monitoring
cycle, the severe inducement will be active after the next restart.
