Diesel Particulate Filter (DPF) Messages

The Cummins® diesel engine meets all diesel

emissions standards, resulting in one of the lowest

emitting diesel engines ever produced. To achieve

these emissions standards, your vehicle is

equipped with a state-of-the-art engine and

exhaust system. These systems are seamlessly

integrated into your vehicle and managed by the

Powertrain Control Module (PCM). The PCM

manages engine combustion to allow the exhaust

system’s catalyst to trap and burn Particulate

Matter (PM) pollutants, with no input or interaction

on your part.

This vehicle is equipped with an Intelligent Battery

Sensor (IBS) to perform additional monitoring of

the electrical system and status of the vehicle

battery.
In cases when the IBS detects charging system

failure, or the vehicle battery conditions are

deteriorating, electrical load reduction actions will

take place to extend the driving time and distance

of the vehicle. This is done by reducing power to or

turning off non-essential electrical loads.
Load reduction is only active when the engine is

running. It will display a message if there is a risk

of battery depletion to the point where the vehicle

may stall due to lack of electrical supply, or will not

restart after the current drive cycle.
When load reduction is activated, the message

“Battery Saver On Some Systems May Have

Reduced Power” will appear in the instrument

cluster.
These messages indicate the vehicle battery has a

low state of charge and continues to lose electrical

charge at a rate that the charging system cannot

sustain.

NOTE:



The charging system is independent from load

reduction. The charging system performs a diag

-

nostic on the charging system continuously.



If the Battery Charge Warning Light is on it may

indicate a problem with the charging system

Ú

page 114.

The electrical loads that may be switched off (if

equipped), and vehicle functions which can be

affected by load reduction:



Heated Seats/Vented Seats/Heated Wheel



Rear Defroster And Heated Mirrors



HVAC System



115 Volts AC Power Inverter System



Audio and Telematics System

Loss of the battery charge may indicate one or

more of the following conditions:



The charging system cannot deliver enough

electrical power to the vehicle system because

the electrical loads are larger than the capability

of charging system. The charging system is still

functioning properly.



Turning on all possible vehicle electrical loads

(e.g. HVAC to max settings, exterior and interior

lights, overloaded power outlets +12 Volts,

115 Volts AC, USB ports) during certain driving

conditions (city driving, towing, frequent stop

-

ping).



Installing options like additional lights, upfitter

electrical accessories, audio systems, alarms

and similar devices.



Unusual driving cycles (short trips separated by

long parking periods).



The vehicle was parked for an extended period

of time (weeks, months).



The battery was recently replaced and was not

charged completely.



The battery was discharged by an electrical load

left on when the vehicle was parked.



The battery was used for an extended period

with the engine not running to supply radio,

lights, chargers, +12 Volts portable appliances

like vacuum cleaners, game consoles and

similar devices.

What to do when an electrical load reduction

action message is present (“Battery Saver On” or

“Battery Saver Mode”)
During a trip:



Reduce power to unnecessary loads if possible:



Turn off redundant lights (interior or exte

-

rior).



Check what may be plugged in to power

outlets +12 Volts, 115 Volts AC, USB ports.



Check HVAC settings (blower, temperature).



Check the audio settings (volume).

GETTING TO KNOW YOUR INSTRUMENT PANEL

113

After a trip:



Check if any aftermarket equipment was

installed (additional lights, upfitter electrical

accessories, audio systems, alarms) and review

specifications if any (load and Ignition Off Draw

currents).



Evaluate the latest driving cycles (distance,

driving time and parking time).



The vehicle should have service performed if

the message is still present during consecutive

trips and the evaluation of the vehicle and

driving pattern did not help to identify the cause.

Sway Bar Fault Warning Light

This light will illuminate when there is a

fault in the sway bar disconnect system.

Tire Pressure Monitoring System (TPMS)

Warning Light

The warning light switches on and a

message is displayed to indicate that the

tire pressure is lower than the

recommended value and/or that slow

pressure loss is occurring. In these cases, optimal

tire duration and fuel consumption may not be

guaranteed.
Should one or more tires be in the condition

mentioned above, the display will show the

indications corresponding to each tire.

Each tire, including the spare (if provided), should

be checked monthly when cold and inflated to the

inflation pressure recommended by the vehicle

manufacturer on the vehicle placard or tire

inflation pressure label. If your vehicle has tires of

a different size than the size indicated on the

vehicle placard or tire inflation pressure label, you

should determine the proper tire inflation pressure

for those tires.
As an added safety feature, your vehicle has been

equipped with a TPMS that illuminates a low tire

pressure telltale when one or more of your tires is

significantly underinflated. Accordingly, when the

low tire pressure telltale illuminates, you should

stop and check your tires as soon as possible, and

inflate them to the proper pressure. Driving on a

significantly underinflated tire causes the tire to

overheat and can lead to tire failure. Underinflation

also reduces fuel efficiency and tire tread life, and

may affect the vehicle’s handling and stopping

ability.
Please note that the TPMS is not a substitute for

proper tire maintenance, and it is the driver’s

responsibility to maintain correct tire pressure,

even if underinflation has not reached the level to

trigger illumination of the TPMS low tire pressure

telltale.
Your vehicle has also been equipped with a TPMS

malfunction indicator to indicate when the system

is not operating properly. The TPMS malfunction

indicator is combined with the low tire pressure

telltale. When the system detects a malfunction,

the telltale will flash for approximately one minute

and then remain continuously illuminated. This

sequence will continue upon subsequent vehicle

start-ups as long as the malfunction exists. When

the malfunction indicator is illuminated, the

system may not be able to detect or signal low tire

pressure as intended. TPMS malfunctions may

occur for a variety of reasons, including the

installation of replacement or alternate tires or

wheels on the vehicle that prevent the TPMS from

functioning properly. Always check the TPMS

malfunction telltale after replacing one or more

tires or wheels on your vehicle to ensure that the

replacement or alternate tires and wheels allow

the TPMS to continue to function properly.

CAUTION!

Do not continue driving with one or more flat

tires as handling may be compromised. Stop the

vehicle, avoiding sharp braking and steering. If a

tire puncture occurs, repair immediately using

the dedicated tire repair kit and contact an

authorized dealer as soon as possible.

CAUTION!

The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures

and warning have been established for the tire

size equipped on your vehicle. Undesirable

system operation or sensor damage may result

when using replacement equipment that is not

of the same size, type, and/or style. Aftermarket

wheels can cause sensor damage. Using

aftermarket tire sealants may cause the Tire

Pressure Monitoring System (TPMS) sensor to

become inoperable. After using an aftermarket

tire sealant it is recommended that you take

your vehicle to an authorized dealer to have your

sensor function checked.

ONBOARD DIAGNOSTIC SYSTEM — OBD II

Your vehicle is equipped with a sophisticated

Onboard Diagnostic system called OBD II. This

system monitors the performance of the

emissions, engine, and 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 Malfunction Indicator Light

(MIL). It will also store diagnostic codes and other

information to assist your service technician in

making repairs. Although your vehicle will usually

be drivable and not need towing, see an authorized

dealer for service as soon as possible.

YBERSECURITY

Your vehicle is required to have an OBD II and a

connection port to allow access to information

related to the performance of your emissions

controls. Authorized service technicians may need

to access this information to assist with the

diagnosis and service of your vehicle and

emissions system

Ú

page 231.

CAUTION!



Prolonged driving with the MIL on could cause

further damage to the emission control

system. It could also affect fuel economy and

driveability. The vehicle must be serviced

before any emissions tests can be performed.



If the MIL is flashing while the vehicle is

running, severe catalytic converter damage

and power loss will soon occur. Immediate

service is required.

WARNING!



ONLY an authorized service technician should

connect equipment to the OBD II connection

port in order to read the VIN, diagnose, or

service your vehicle.



If unauthorized equipment is connected to the

OBD II connection port, such as a

driver-behavior tracking device, it may:



Be possible that vehicle systems,

including safety related systems, could be

impaired or a loss of vehicle control could

occur that may result in an accident

involving serious injury or death.

EMISSIONS INSPECTION AND

MAINTENANCE PROGRAMS

In some localities, it may be a legal requirement to

pass an inspection of your vehicle's emissions

control system. Failure to pass could prevent

vehicle registration.

For states that require an Inspection and

Maintenance (I/M), this check verifies

the Malfunction Indicator Light (MIL) is

functioning and is not on when the

engine is running, and that the OBD II system is

ready for testing.
Normally, the OBD II system will be ready. The

OBD II system may not be ready if your vehicle was

recently serviced, recently had a depleted battery

or a battery replacement. If the OBD II system

should be determined not ready for the I/M test,

your vehicle may fail the test.
Your vehicle has a simple ignition actuated test,

which you can use prior to going to the test station.

To check if your vehicle's OBD II system is ready,

you must do the following:

1. Cycle the ignition switch to the ON position,

but do not crank or start the engine.

NOTE:

If you crank or start the engine, you will have to

start this test over.
2. As soon as you cycle the ignition switch to the

ON position, you will see the Malfunction

Indicator Light (MIL) symbol come on as part of

a normal bulb check.

3. Approximately 15 seconds later, one of two

things will happen:



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 ready and 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

ready and you can proceed to the I/M

station.

If your OBD II system is not ready, you should see

an 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.
