Each time the car is started turning the ignition key to MAR, the Fiat CODE system control unit sends a recognition code to the engine control unit to deactivate the inhibitor.

The code is sent only if the Fiat CODE system control unit has recognised the code transmitted from the key.

Each time the ignition key is turned to the STOP position, the Fiat CODE system deactivates the functions of the engine electronic control unit.

At starting, if the code has not been recognised correctly, the warning light will come on.

In this case, the key should be moved to the STOP position and then back to MAR; if the lock continues, possibly try again with the other key provided with the car. If it is still not possible to start the car, follow the instructions given in chapter “In an emergency” and then contact a Fiat Dealership.

IMPORTANT Every key has its own code, which must be memorised by the system control unit. To memorise new keys, up to a maximum of eight, apply to Fiat Dealership.

Warning light coming on when driving

❒ If the warning light turns on, this means that the system is running a self-test (for example for a voltage drop). At the first stop, turn the ignition key to STOP and then to MAR again: if no failure is detected warning light will not come on.
❒ If the warning light Y stays on, repeat the procedure described previously leaving the key at STOP for over 30 seconds. Should the inconvenience persists, contact a Fiat Dealership.
❒ If the warning light Ystays on this means that the code has not been recognised. In this case, the key should be moved to the STOP position and then back to MAR; if the lock continues, possibly try again with the other key provided with the car. If it is still not possible to start the car, follow the instruction given in chapter “In an emergency” and then contact a Fiat Dealership.

The electronic components inside the key may be damaged if the key is submitted to sharp knocks.
