Eobd System (European On Board Diagnosis) - Jeep COMPASS Owner's Handbook Manual

EOBD SYSTEM (European
On Board Diagnosis)
(where provided)
OPERATION
The EOBD system (European On Board
Diagnosis) carries out a continuous
diagnosis of the components of the car
related to emissions.
It also alerts the driver, by switching on
the warning light or icon (according
to the version of the display)
the instrument panel, together with a
message on the display, when these
components are no longer in peak
condition (see "Warning lights and
messages" chapter in this section).
The aim of the EOBD system (European
On Board Diagnosis) is to:
monitor system efficiency;
indicate an increase in emissions;
indicate the need to replace damaged
components.
The car 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 also be carried
out by the traffic police.
WARNING After eliminating an anomaly,
to check the system completely, a Jeep
Dealership is obliged to run tests and,
68
if necessary, road tests which may also
require a long journey.
