Electronic Control Units
Each system installed on the vehicle is
controlled by an electronic control unit
(ECU) equipped with microprocessor for
high-speed data processing of the data
acquired from the sensors and transducers.
The features common to all the ECUs are:
Self-diagnostic functions for the
relevant system
Each ECU detects functional faults in the
components of the system it controls.
These faults are recorded as errors and
promptly signalled to the user through the
warning lights on the instrument panel.
Remote diagnostic functions
The ECUs can be connected to the "SD-3
diagnostic system".
This is an instrument made available to the
Ferrari Service Network and allows:
• finding the origin of an error recorded
by the ECU and guiding the workshop
technician through solving the problem
• acquiring the values of the measurements
made during vehicle testing
• running an automatic test cycle of the
individual systems
• analysing the data acquired by the ECUs
• deleting the errors detected while
driving.
Error management
The errors are recorded in an "erasable"
memory at the time of system testing and/
or repair and in an non-erasable "historical"
memory, thus providing a complete picture
of the faults found during the lifetime of
the vehicle.
Connection to the CAN line
(Controller Area Network)
This is a communication line which allows
high-speed data transfer between all
the ECUs with high immunity against
disturbances.
This allows the ECUs to intelligently
"cooperate" in vehicle control.
6 - Technical Information
Diagnostic tester socket
The vehicle is equipped with a universal
connector located under the lower
dashboard covering, in correspondence to
the steering column, to connect the SD-3
diagnostic tester.
By means of this plug-in connection, the
tester can interface with all the vehicle's
systems and carry out the diagnosis testing.
