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 emis-
sions, engine, and transmission control sys-
tems. When these systems are operating prop-
erly, your vehicle will provide excellent
performance and fuel economy, as well as en-
gine 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 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.
