GETTING TO KNOW YOUR INSTRUMENT PANEL 217
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.
For further information, refer to “Cybersecurity” in “Multi-
media”.
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 Mainte-
nance (I/M), this check verifies the “Malfunction
Indicato
r 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 ma
y not be ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace
-
ment. If the OBD II system should be determined not ready
for the
I/M test, your vehicle may fail the test.
WARNING!
• ONLY an authorized service technician should connect
equipme
nt 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
connecti
on 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 ve
hicle systems, including personal infor-
mation.
