What it means
INJECTION / EOBD SYSTEM FAILURE
Under normal conditions, the warning light comes on when the ignition key is turned to MAR, but should
go off as soon as the engine is started.
The warning light remains on or switches on while driving, on some versions together with a dedicated
message on the display, if the injection system is not working properly. In particular, if the warning light
switches on continuously, it indicates a malfunction in the supply/ignition system that could cause
excessive exhaust emissions, a possible loss of performance, poor driveability and high fuel consumption.
Under these conditions, the vehicle can continue travelling at moderate speed without demanding
excessive effort from the engine. Prolonged use of the car with the warning light on may cause damage.
Contact a Fiat Dealership as soon as possible.
If the warning light is flashing, this indicates that the catalytic converter may be damaged.
If the light flashes, come off the accelerator pedal to reduce engine revs until the warning light stops
flashing; continue the journey at moderate speed, trying to avoid driving conditions that may cause further
flashing, and get to a Fiat Dealership as soon as possible.
