ONBOARD
DIAGNOSTIC
SYSTEM
Operation
The OBD (On Board Diagnostic system)
carries out a continuous diagnosis of
the components of the vehicle related
to emissions.
It also alerts the driver of when these
components are no longer in peak
condition by switching on the
warning light on the instrument
panel (see “Warning Lights And
Messages” paragraph in this chapter).
The aim of the OBD system (On Board
Diagnostic) is to:
Monitor the efficiency of the system
Indicate an increase in emissions
Indicate the need to replace
damaged components
The vehicle also has a connector, which
can interface with appropriate tools,
that makes it possible to read the error
codes stored in the electronic control
units together with a series of specific
parameters for engine operation and
diagnosis. This check can be carried
out by your authorized dealer.
Note: After eliminating a fault, to check
the system completely, your authorized
dealer is obliged to run tests and, if
necessary certain road tests.
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.
