KNOWING THE INSTRUMENT PANEL

EOBD SYSTEM (European
On Board Diagnosis)
(where provided)
OPERATION
The EOBD (European On Board
Diagnosis) system continuously monitors
vehicle components related to emissions.
It also indicates the extent to which
these components have deteriorated (see
"Indicator lights and messages” chapter
in this section) by switching on the
indicator light on the instrument panel,
and a message on the display.
The aim of the EOBD system (European
On Board Diagnosis) is to:
Monitor the system's efficiency
Indicate an increase in emissions
Indicate the need to replace damaged
components
The vehicle also has an electrical
connector, which can interface with
appropriate tools, to read error codes
stored in the electronic control units
together with a series of specific
parameters for engine operation and
diagnostics. This check can also be
carried out by traffic control officers.
WARNING Once the fault has been
corrected, to fully check the system, a
Jeep Dealership must run bench tests
and, if necessary, road tests, which may
also call for long journeys.
