Ferrari 458 Italia, Technical Documentation Manual

Page: 1671 / 2012

The Ferrari CODE ECU only permits engine start once it has recognised the signal.
Whenever the ignition key is removed from the 0 position, the system activates the engine immobiliser.
On engine start, pressing the ENGINE START button on the steering wheel:
if the code is recognised, the CODE indicator light on the instrument panel goes out after the check cycle,
while the EOBD indicator light extinguishes at the end of the ECU diagnostic cycle, only once the engine
has effectively started: this means that the security system has recognised the key code and disabled the
engine immobiliser;
if the CODE indicator light remains lit, this means that the code has not been recognised: Should this occur,
turn the key back to 0 position and then to II position. If the engine immobiliser is still not deactivated, try
with the other key provided.
With the vehicle running with the ignition key turned to II position:
the CODE indicator light illuminates when the system is running a self diagnosis cycle. The next time the
vehicle is stopped, the system may be tested as follows. Switch off the engine by turning the ignition key
to 0 position, then turn the key back to II position. The CODE indicator light should illuminate and
extinguish again within one second. If the indicator light remains lit, leave the key in the 0 position for more
than 30 seconds and repeat the above procedure;
the CODE indicator light flashes to indicate that the vehicle is not protected by the immobiliser system.
