check engine light DODGE RAM 2500 DIESEL 2004 3.G User Guide

²After the WAIT TO START light goes off, turn the
ignition key to START. Do not press the accelerator
during starting.
²Check to see that there is oil pressure.
²Allow the engine to idle at fast idle for about three
minutes until the manifold heaters have completed
the post-heat cycle.
²Release the parking brake and drive.
NOTE:Engine idle speed will automatically increase to
1000 rpm at low coolant temperatures to improve engine
warm-up.
NOTE:If the engine stalls or if the ignition switch is left
On for more than 2 minutes after the WAIT TO START
light goes out, reset the grid heaters by turning the
ignition switch to Off and the back On. Repeat steps 3
through 7 of the normal starting procedure.
For Extremely Cold Weather Starting (Engine
Temperature Below 0ÉF (- 18ÉC)
In extremely cold weather below 0ÉF (- 18ÉC) it may be
beneficial to cycle the manifold heaters twice before
attempting to start the engine. This can be accomplished
by turning the ignition OFF and then back ON after the
WAIT TO START light has gone off, but before the engine
is started. However, repeated cycling of the manifold
heaters will result in damage to the heater elements or
reduced battery voltage.
NOTE: If multiple pre-heat cycles are used before
starting, additional engine run time may be required to
maintain battery state of charge at a satisfactory level.
²If the engine stalls after the initial start, the ignition
must be turned to the OFF position and then to the ON
position to recycle the manifold heaters.
NOTE:Excessive white smoke and poor engine perfor-
mance will result if manifold heaters are not recycled.
208 STARTING AND OPERATING

WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
NORMAL OPERATION
Observe the following when the engine is operating.
²All message center lights are off.
²Check Engine Lamp is off.
²Engine Oil Pressure is above 10 psi (69 kPa) at idle.
²Low Oil Pressure light is off.
²Voltmeter Operation:
²The voltmeter may show a gauge fluctuation if
certain engine temperatures are below 66ÉF (19ÉC).
This cycling operation is caused by the post-heatcycle of the intake manifold heater system. The
number of cycles and the length of the cycling
operation is controlled by the engine control mod-
ule, this time will not exceed 150 seconds. The
needle should then stabilize at the approximate
operation point.
²The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.
Cold Weather Precautions
Operation in ambient temperature below 32ÉF (0ÉC) may
require special considerations. The following charts sug-
gest these options:

Apply a light film of lubricating oil to the sealing surface
of the filter gasket before installing the filter.
CAUTION!
Overtightening may distort the threads or damage
the filter element seal.
Install the filter as specified by the filter manufacturer.
Turn the filter 3/4 to one full turn after making contact
with the gasket.
Check the condition of the threads and sealing surface on
the oil pan and drain plug.
Install the drain plug and sealing washer and tighten to
37 ft-lbs. (50 N´m).Use only high-quality multi-grade lubricating oil in your
Cummins Diesel Engine. Choose the correct oil for your
operating conditions as outlined in the Selection of
Engine Oil.
Cummins Turbo Diesel
Fill the engine with the correct grade of new oil. The
engine capacity is 11 quarts (10.4 liters) in the crankcase
and 1 quart (.95 liter) in the lubricating oil filter.
Start the engine and operate it at idle for several minutes.
Check for leaks at the lubricating oil filter and oil pan
drain plug.
Stop the engine. Wait approximately 15 minutes to let the
oil in the upper parts of the engine drain back to the pan.
Check the oil level again.
Add oil as necessary to bring the level to the ªSAFEº
mark on the dipstick.
330 MAINTAINING YOUR VEHICLE

²Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and transfer case (if
equipped), add as needed.
²Check Filter MinderŸ. Replace air cleaner filter
element if necessary.
²Check all lights and all other electrical items for correct
operation.
At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
²Inspect the brake hoses.
²Inspect the CV joints (if equipped) and front suspen-
sion components.
²Check the automatic transmission fluid level.
²Check the manual transmission fluid level.
²Check the coolant level, hoses, and clamps.
