The system consists of a throttle valve with a re-
turn spring placed on the exhaust pipe. The valve
is closed via two cables actuated by an electric
motor, which, in turn, is connected electrically to
the instrument panel. The operating logic and mo-
tor control are, however, resident in the Marelli
injection control unit, which dialogues with the in-
strument panel via the CAN.
