Fast Idle Control Device (F.I.C.D.) was fitted to some Datsuns with factory-fitted Aircon. The FICD raises the idle speed automatically when A/C is ON to respond to the increased load.

Contents

Overview

FICD consists of two parts, a throttle actuator, and a magnetic vacuum switch. The switch is electrically operated off the compressor signal. The switch then lets vacuum go to the actuator, which pulls the carburetor throttle a little (about 100 RPM).

Magnetic Switch

The magnetic switch is on the side of the compressor, and opens when the compressor activates.
