Via the aerial for the Fiat-CODE system
P091, the body computer
node M001 receives, at pins 10 and 19 of connector H, the code of
the inserted key, and checks that it is valid by comparing it with
those in its memory.
Functional description
If the code is correct, the body computer
node
M001, via the CAN network, enables at pins 20 and 29 of
connector B the control unit M010 to start the engine when required
and, still via the B CAN network, controls the switching on of the
warning lights on the instrument panel E050.
Functional description
The system is only activated
if the ignition is on; the signal reaches the body computer node
at pin 1, connector L (for further details
See E1010 SUPPLY
).
