During engine idle operation, ECM controls duty of
conduction between generator G terminal and
ground. (G terminal duty is controlled to be the same
as ON duty of the power transistor inside the voltage
regulator). If headlights etc. are turned on while
engine is idling, the consumed current increases
suddenly, but by gradually increasing the generator G terminal OFF duty, ECM restricts sudden increase
in generator's output current and output current is
increased only gradually. (Battery current is supplied
to the headlamp etc. till generator produces sufficient
current.) Thus, ECM prevents change in idle speed
due to sudden increase of engine load.

The ECM detects whether the fuel vapor leakage
exists or not from the evaporative emission control
system. By the specified pattern within the certain
operation range, the ECM drives the evaporative
emission purge solenoid and the evaporative emis
-
sion ventilation solenoid. This allows slight vacuum
to be produced in the fuel tank.
The ECM measures the vacuum condition through
the fuel tank differential pressure sensor signal. By
comparing the normal (expected) value and the
actual value, the ECM detects whether the fuel vapor
leakage exists or not from the evaporative emission
control system.
