ONBOARD DIAGNOSTIC
SYSTEM
Operation
The Onboard Diagnostic system (OBD) carries
out a continuous diagnosis of the components
of the vehicle related to emissions.
It also alerts the driver of when these compo
-
nents are no longer in peak condition by
switching on the warning light on the instru
-
ment panel. See “Warning Lights And
Messages” paragraph in this chapter.
The aim of the OBD system (Onboard Diag
-
nostic) 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 an authorized dealer.
NOTE:
After eliminating a fault, to check the system
completely, an authorized dealer is obliged to
run tests and, if necessary certain road tests.
