OPERATION

Each time the vehicle is started turning the

ignition key to MAR, the Fiat CODE sys-

tem 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

STOP, the Fiat CODE system deactivates

the functions of the engine control unit.

If the code has not been recognised cor-

rectly, the warning light

turns on ac-

companied by the related message on the

display.

In this case, turn the key to STOP and

then back to MAR; try with the other

keys provided if the problem persists.

Contact a Fiat Dealership if you still can-

not start the engine.

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).

❒ If the warning light

stays on, con-

tact a Fiat Dealership.

The electronic components

inside the key may be dam-

aged if the key is subjected to

sharp knocks.
