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 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
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 your 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 engine is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
Onboard Diagnostic
System (OBD II)
Cybersecurity
Your vehicle is required to have an
Onboard Diagnostic system (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 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.
