At key-ON, the variable geometry control unit low-
ers the ducts (if still in the raised position). Subse-
quently, depending on the control voltage on PIN
2 from the injection control unit (0V down, 5V up),
the control unit drives the electric motor with the
relative polarity for raising or lowering the ducts.
The drive voltage delivered to the motor is deter-
mined in relation to battery voltage and the motor
is stopped once a given current limit is reached or
if the time-out period of 500 ms has elapsed.
