Idle Speed Control Actuator: Description and Operation
IDLE SPEED CONTROL (ISC) ACTUATOR
The Idle Speed Control (ISC) actuator has two coils that are driven by separate ECM driver stages. Depending on the pulse duty factor, the equilibrium
of the magnetic forces of the two coils will result in different direction for the magnetic forces of the two coils which will result in different positions for
the actuator. In parallel to the throttle valve, a bypass hose line is arranged where the ISC actuator is inserted.
