DDEC VI SYSTEM
the parking brake is not set. Activating
or momentarily changing the position
of the service brake pedal, the clutch
pedal, Stop Engine Override, the
accelerator pedal, or park brake status
during the final 30 seconds before
a shutdown would otherwise occur
will prevent the engine from shutting
down and will reset the shutdown
timer. After an automatic shutdown,
the engine may be restarted and
operated normally. The automatic
shutdown feature is generally disabled
on engines certified by the US EPA for
use outside California but is required
to be enabled for all California
certified engines with the exception
of engines used in specific vehicle
types which the state of California
has determined to be exempt from
the idle shutdown requirement.
These include buses, school buses,
recreational vehicles, medium duty
vehicles, military tactical vehicles,
and authorized emergency vehicles
as they are defined by the state of
California. Owners of these vehicle
types that wish to have the shutdown
feature disabled should consult with
California authorities to determine
if their vehicles qualify for the
exemption.

allowing a turbocharger cool-down

transmission must be in neutral with
the vehicle parking brakes set and the
engine in idle or fast-idle mode.

DDEC VI Operation

NOTE:
This engine is equipped with DDEC
software. This software generally
assures optimal engine performance.
The installation of software upgrades
may cause minor changes in features
and engine performance.
Since the DDEC system is electronic,
a battery is required to operate the
computer. The system operates at
12 volts DC. However, in the event
of a power supply malfunction, the
system will continue to operate at
reduced voltage. When this occurs,
the AWL (Check Engine) will come
on. See Figure 21.
