For all engines this feature is already turned on.
The automatic quick warm-up on the DURAMAX
®
engine can be turned off and on by doing the
following procedure:
1. Turn the ignition to RUN, with the vehicle off.
2. Press the accelerator pedal to the floor
and hold it while quickly pressing and
fully releasing the brake pedal three times in
less than eight seconds.
3. Release the accelerator pedal and start the
engine. The green exhaust brake/restrictor
light below the radio controls will be lit
for 10 seconds.
If this feature is turned off, by doing the
procedure described previously, and then the
engine is started, the exhaust brake/restrictor
light will flash for 10 seconds and then it
will turn off.
When the engine is started, it will slowly increase
to the high idle speed after a delay of a few
seconds; up to about two minutes. For this method
to work properly there must be no throttle or
brake pedal faults, and the throttle pedal must not
fall below 75 percent of wide open throttle while
pressing the brake pedal.
The engine idle speed will return to normal once
the following conditions are met:
•
Once engine coolant temperature reaches
about 150°F (65°C).
•
The intake temperature reaches a certain level.
The high idle speed will be temporarily interrupted
and the engine speed will return to normal if
any of the following conditions occur:
•
The brake pedal is applied.
•
The accelerator pedal is pressed.
•
The automatic transmission is shifted out of
PARK (P) or NEUTRAL (N).
•
The clutch pedal on the manual transmission
is pressed.
•
Vehicle speed is detected.
Once these conditions no longer exist, the engine
idle speed will slowly increase to high idle after
the normal delay, if the conditions for engine
coolant temperature and air intake temperature
are still met.
