Fast Idle Control Device (F.I.C.D.): Description and Operation

Idle Air Control Valve-FICD

PURPOSE

Increases idle speed when the A/C compressor is engaged.

LOCATION

Located on the IAA unit.

OPERATION

When voltage is applied to the coil of the A/C compressor clutch, voltage is also supplied to the Fast Idle control Device (FICD). The FICD
becomes energized and opens an additional air pasage. Air by-passes the throttle valve, thereby raising idle speed.
