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 con-
trol 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.
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. Autho-
rized 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:
WARNING!
• Be possible that vehicle systems, in-
cluding safety related systems, could
be impaired or a loss of vehicle control
could occur that may result in an ac-
cident involving serious injury or
death.
• Access, or allow others to access, in-
formation stored in your vehicle sys-
tems, including personal information.
