ONBOARD DIAGNOSTIC SYSTEM (OBD II)
CARB emission control vehicles are equipped with a
sophisticated onboard diagnostic system called OBDII.
This system monitors the performance of the emissions,
engine, and automatic transmission control systems.
When these systems are operating properly, your vehicle
will provide excellent performance and fuel economy, as
well as engine emissions well within current government
regulations.
If any of these systems require service, the OBD II system
will turn on the ªMalfunction Indicator Light.º It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be driveable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
Prolonged driving with the ªMalfunction Indicator
Lightº on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
If the ªMalfunction Indicator Lightº is flashing,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

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.

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.

To determine the battery charge, check the battery test
indicator (if equipped) on top of each battery. If the test
indicator (if equipped) appears light or yellow, replace
the battery.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle's charging
system.CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked (+) positive
and negative (-) and identified on the battery case.
Also, if a ªfast chargerº is used while battery is in
vehicle, disconnect both vehicle battery cables be-
fore connecting the charger to battery. Do not use a
ªfast chargerº to provide starting voltage.
WARNING!
Battery posts, terminals, and related accessories con-
tain lead and lead compounds. Always wash hands
after handling the battery.

It is important that proper lubricant is used in the
transmission. Refer to Recommended Fluids, Lubricants
and Genuine Parts for the correct lubricant type. A band
adjustment and filter change should be made at the time
of the oil change.
The fluid and filter should be changed and the bands
adjusted as specified in the Maintenance Schedule (Sec-
tion 8). Vehicles having severe usage should follow
Maintenance Schedule ªBº of the Maintenance Schedule
(Section 8).
Severe usage consists of:
²Off-the-highway operation;
²Trailer towing;
²Snow plow operation;
²Prolonged operation with heavy loading, especially in
hot weather.NOTE:If the transmission is disassembled for any
reason, the fluid and filter should be changed, and the
bands adjusted.
Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. The use of transmission sealers should be avoided,
since they may adversely affect seals.
Front Wheel Bearings
Front wheel bearings for all Dodge Ram Trucks are
sealed-for-life. They do not require greasing or seal
replacement. In some instances, these bearings will
ªpurgeº excess grease and the bearing housing will look
slightly wet. This is normal.
²Periodic inspection for excess play is recommended.
