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.
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.

YBERSECURITY
Your vehicle is required to have 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
.
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, information
stored in your vehicle systems, including
personal information.
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
