68GETTING TO KNOW YOUR INSTRUMENT PANEL
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
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 119.
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.
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. Switch the ignition 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.
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.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.

The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC)
monitors the internal circuits and interconnecting
wiring associated with the electrical Air Bag System
Components. Your vehicle may be equipped with the
following Air Bag System Components:

Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the AVV (START) or
MAR (ACC/ON/RUN) position. If the ignition switch
is in the STOP (OFF/LOCK) position the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
in the MAR (ACC/ON/RUN) position. After the
self-check, the Air Bag Warning Light will turn off.
If the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system
is designed to be maintenance free, if any of the following occurs, have an authorized dealer
service the air bag system immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the igni
-
tion switch is first in the MAR (ACC/ON/RUN)
position.
The Air Bag Warning Light remains on after the
four to eight-second interval.
The Air Bag Warning Light comes on intermit -
tently or remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be disabled.
In this condition the air bags may not be ready to
inflate for your protection. Have an authorized
dealer service the air bag system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have the
air bag system to protect you in a collision. If the
light does not come on as a bulb check when the
ignition is first turned on, stays on after you start
the vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag system
immediately.

SAFETY CHECKS YOU SHOULD MAKE
I
NSIDE THE VEHICLE
Seat Belts
Inspect the seat belt system periodically, checking
for cuts, frays, and loose parts. Damaged parts
must be replaced immediately. Do not
disassemble or modify the system.
If your vehicle is involved in a collision, or if you
have questions regarding the seat belt or retractor
conditions, take your vehicle to an authorized FCA
dealer or authorized FCA Certified Collision Care
Program facility for inspection.
Air Bag Warning Light
The Air Bag Warning Light will turn on for
four to eight seconds as a bulb check
when the ignition switch is first placed in
the MAR (ACC/ON/RUN) position. If the
light is either not on during starting, stays on, or
turns on while driving, have the system inspected
at an authorized dealer as soon as possible. After
the bulb check, this light will illuminate with a
single chime when a fault with the Air Bag System
has been detected. It will stay on until the fault is
removed. If the light comes on intermittently or
remains on while driving, have an authorized
dealer service the vehicle immediately
Ú page 154.
Defroster
Check operation by selecting the defrost mode and
place the blower control on high speed. You should
be able to feel the air directed against the
windshield. See an authorized dealer for service if
your defroster is inoperable.
