Reduced Power Mode (Engine Derating Mode) When a fault is detected, the ECU determines the severity of the fault and may take action to protect either the engine or the machine from potential damage.

The ECU can decide on four possible actions:

No Action:

The ECU has determined that there is no immediate risk to the engine or machine and the engine operates as normal. However action should be taken at the earliest opportunity to rectify the fault.

Reduced Torque Mode:

The power output of the engine is reduced so that stresses and temperatures in the engine are lowered and engine damage is minimized. The machine should be stopped at the earliest opportunity to avoid further damage.

Limp Home Mode:
