Traction Plus operation
The system is deactivated when starting up. To
activate the "Traction Plus" system, press the button
(T+ fig. 91): the LED on the button switches on.
The activation of the Traction Plus system involves
the following functions being switched on:
❒inhibition of the ASR function, in order to fully
exploit the engine torque;
❒the differential locking effect on the front axle,
through the braking system, to improve traction
on irregular grounds.
If the "Traction Plus" system is faulty, the "general
failure" instrument panel warning light
comes on
steady.
EOBD SYSTEM
The EOBD system (European On Board Diagnosis)
allows continuous diagnosis of emission-related
components on the vehicle. It also alerts the driver,
by turning on instrument panel warning light
(together with the relevant message in the
display, on some versions), when these components
are no longer in peak condition (see “Warning
lights and messages” section).
The aim of the system is to:
❒monitor system efficiency;
❒warn about increased emissions due to a vehicle
malfunction;
❒to warn of the need to replace deteriorated
components.
The system also has a connector that can be
interfaced with appropriate equipment, which makes
it possible to read the error codes stored in the
control unit, together with a series of specific
parameters for engine operation and diagnosis.
This check can also be carried out by traffic police.
IMPORTANT After resolving the problem, to check
the system completely, Fiat Dealerships are obliged
to run a bench test and, if necessary, road tests
which may call for a long journey.
