Operation; Idle Shutdown - Chevrolet 2009 Kodiak Owner's Manual

Idle Shutdown

If the vehicle has a diesel engine it could have an
engine idle shutdown feature.
This feature automatically shuts down the engine after it
idles continuously for five minutes and if the following
conditions are met:
•
The parking brake is set.
•
The vehicle is at a complete stop.
•
The automatic transmission is in N (Neutral) or
P (Park).
If the parking brake is not engaged, then the engine
shuts down after 15 minutes of continuous idling

operation.

The driver can reset the engine shutdown timer by
momentarily changing the position of the accelerator,
brake, or clutch pedal or by shifting the transmission out
of P (Park) or N (Neutral). Once reset, the engine idle
shutdown will restart the shutdown sequence described
above, and will continue to do so until the engine
shuts down or the vehicle is driven.
The engine will not go into idle shutdown mode if:
•
The Power Take-Off (PTO) equipment is operating.
See Power Take-Off (PTO) on page 2-30 for more
information.
•
The engine coolant temperature is below 60°F.
The engine idle shutdown will be activated once
the vehicle coolant reaches 60°F or above.
•
The Diesel Particulate Filter (DPF) is in regeneration
mode and the green DPF lamp is illuminated to
notify the driver that DPF is regenerating. The
engine idle shutdown mode will be overridden for
the time necessary to complete the regeneration
process, up to a maximum of 30 minutes.
•
Service or maintenance is being performed on the
engine. The engine idle shutdown mode may be
deactivated, by using a diagnostic scan tool,
for a period of up to a maximum of 60 minutes.
