battery Ram 3500 2015 Repair Manual

3. Approximately 15 seconds later, one of two things willhappen:
• The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not readyand you should
not proceed to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you place the ignition in the off
position or start the engine. This means that your
vehicle’s OBD II system is readyand you can proceed
to the I/M station.
If your OBD II system is not ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II system to update. A recheck with the above test routine
may then indicate that the system is
now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.
REPLACEMENT PARTS
Use of genuine MOPAR® parts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPAR® parts for mainte-
nance and repairs will not be covered by the New Vehicle
Limited Warranty.7

Conditions that would require replacement:
•Rib chunking (one or more ribs has separated from belt
body)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs)
• Belt slips
• “Groove jumping (belt does not maintain correct
position on pulley)
• Belt broken (note: identify and correct problem before
new belt is installed)
• Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty component
such as a belt pulley. Belt pulleys should be carefully
inspected for damage and proper alignment. Belt replacement on some models requires the use of
special tools, we recommend having your vehicle ser-
viced at an authorized dealer.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.
WARNING!
•
Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid
to contact your eyes, skin, or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water. Refer to
“Jump-Starting Procedures” in “What To Do In
Emergencies” for further information.

WARNING!(Continued)
•Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.
• Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.
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 are identified on the
(Continued)
CAUTION! (Continued)
battery case. Cable clamps should be tight on the
terminal posts and free of corrosion.
• If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables be-
fore connecting the charger to the battery. Do not
use a “fast charger” to provide starting voltage.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.7

Power Distribution Center
The Power Distribution Center is located in the engine
compartment near the battery. This center contains car-
tridge fuses, micro fuses, relays, and circuit breakers. A
description of each fuse and component may be stamped
on the inside cover, otherwise the cavity number of each
fuse is stamped on the inside cover that corresponds to
the following chart.

CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If
a properly rated fuse continues to blow, it indicates
a problem in the circuit that must be corrected.
VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
• Disconnect the negative cable from battery.
• Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
