Fiat Punto: EOBD system

Fiat Punto Owners Manual

The EOBD system (European On Board Diagnosis) allows continuos diagnosis of the components of the car correlated with emissions.

It also alerts the driver, by the turning on of the warning light on the instrument
panel together with the message on the reconfigurable multifunction display (where required) (see section “Warning lights and messages”), when these conditions are no longer in peak conditions.

The objective is:

• to keep system efficiency under control;
• warn when a fault causes emission levels to increase;
• warn of the need to replace deteriorated components.

The system has a diagnostic connector that can be interfaced with appropriate tools, 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 performed by traffic controller agents.

IMPORTANT After eliminating the inconvenience, to check the system completely, Fiat Dealership is obliged to run a bench test and, if necessary, road tests which may also call for a long journey.

If turning the ignition key to MAR, the warning light does not turn on or if, while travelling it turns on glowing steadily or flashing together with the message on the reconfigurable multifunction display (where required), contact Fiat Dealership as soon as possible. Warning light operation can be checked by means of special equipment. Always comply with the traffic regulations in force in the country where you are travelling.
