QSB4.5 Engine

Idle Shutdown

Feature Description

The idle shutdown feature reduces the amount of fuel burned
and increases engine life by shutting down the engine after a
period of engine idling with no driver activity.

Before the shutdown will occur a flashing warning lamp will warn
the driver of an impending shutdown. The driver can override the
shutdown by depressing the service brake, clutch or accelerator
pedal during the warning period. This activity will override the
idle shutdown. Idle shutdown operates when the engine is in the
Power TakeOff (PTO) mode unless a specific load threshold is
exceeded. Idle shutdown can be automatically overridden during
cold ambient temperatures if equipped with an OEM supplied
ambient air temperature sensor.

The following table indicates when manual and automatic
overrides are available.

Driver Activation/Deactivation

The driver can not activate or deactivate the idle shutdown
feature. This feature can only be activated or deactivated by the

Cummins INSITE

TM

service tool.

To override the automatic idle shutdown the driver will need to
activate the brake, clutch or accelerator pedal during the 30
second period prior to shutdown. 30 seconds prior to the
shutdown a flashing warning lamp will notify the driver that
engine shutdown is pending. This action will override idle
shutdown. If the override is successful the warning lamp will
flash every one half second for two minutes.

Interaction with other Features and Parameters

Idle shutdown can interact with the PTO feature. Idle shutdown
can cause the engine to shutdown when in PTO mode. If the idle
shutdown percent load threshold is not exceeded the engine will
be shutdown.

It is required that this feature be enabled with the ICON

TM

product and the ambient air temperature override must be
disabled.

Disadvantages

The idle shutdown feature will not activate if Fault Code 241 is
active.

When stopped in traffic for extended periods the engine will be
shutdown.
