EATS Inducements
Low tank level
1 When the level in the DEF tank falls to 15%, a warning lamp lights up.
2 When the tank level has dropped to around 6% the warning lamp will flash. Engine torque will drop to 75%.
Ramp-down takes around 1 minute.
3 The engine will drop to idle with a 50% torque reduction 7 minutes after the tank level reaches 6%. Ramp-
down takes around 3 minutes.
4 If the engine is started when the tank level falls below 6%, the engine will only run at idle.
5 For the engine to revert to full power the tank level must be above 12%. The tank level must be above 21%
for the system to extinguish the warning lamp and cancel the fault message.

the fault is not remedied after 3.5 hours engine torque will drop to 75%. Ramp-down takes around 1 minute.
The warning lamp flashes.
3 After 27 minutes the engine will drop to idle with a 50% torque reduction. Ramp-down takes around 3
minutes.
4 Following re-start, the engine will run at idle with a 50% torque reduction. DEF quality problems will require
service tools to reset the system.
5 When component faults are remedied the engine will revert to full power.
6 Depending on the installation, it is possible after the first 3.5 hours, but before 4 hours, to manually override
the system actions and run the engine at full power for 2 x 10 minutes. After 10 minutes the engine drops
to 75% power. Each 10-minute period requires a manual activation.
7 If an additional fault recurs within 40 hours after the first fault was remedied, available running time will be
reduced to 30 minutes from the moment the fault is detected.
