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 on the instrument
panel, together with a message on the
display, when these components are no
longer in peak condition (see “Warning
lights and messages” paragraph in this
chapter).
The aim of the EOBD system (European
On Board Diagnosis) 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 also be carried
out by the traffic police.
IMPORTANT After eliminating a fault,
to check the system completely, a Jeep
Dealership is obliged to run tests and,
if necessary, road tests which may also
require a long journey.

WARNING LIGHTS AND MESSAGES
IMPORTANT The warning light switches on together with a dedicated message and/or acoustic signal when applicable. These
indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative to the
information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always refer to the
information in this chapter in the event of a failure indication.
IMPORTANT The failure indicators appearing on the display are divided into two categories: very serious and less serious
faults. Serious faults are indicated by a repeated and prolonged warning "cycle". Less serious faults are indicated by a
warning "cycle" with a shorter duration. The display cycle of both categories can be interrupted. The instrument panel
warning light will stay on until the cause of the failure is eliminated.
WARNING LIGHTS ON INSTRUMENT PANEL
Red warning lights
Warning light What it means
INSUFFICIENT BRAKE FLUID / ELECTRIC PARKING BRAKE ON
Low brake fluid level
The warning light turns on when the level of the brake fluid in the reservoir falls below the minimum
level, possibly due to a leak in the circuit. Restore the brake fluid level, then check that the warning
light has switched off. If the warning light stays on, contact a Jeep Dealership.
Electric parking brake on
The warning light switches on when the electric parking brake is engaged. In the event of failure, the
warning light flashes for about 10 seconds and then turns off. Release the electric parking brake, then
check that the warning light has switched off. If the warning light stays on, contact a Jeep Dealership.

Warning light What it means
EBD FAILURE
The simultaneous switching on of the
(red) and(amber) warning lights with the engine on
indicates either a fault of the EBD system or that the system is not available. In this case, the rear
wheels may suddenly lock and the vehicle may swerve when braking sharply. The display shows the
dedicated message.
Drive very carefully to the nearest Jeep Dealership to have the system inspected immediately.
POWER STEERING FAILURE
If the warning light remains on, you could not have steering assistance and the effort required to
operate the steering wheel could be increased; steering is, however, possible.
On some versions the display shows the dedicated message.
Contact a Jeep Dealership as soon as possible.
