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.

Fast Idle Actuator

  1. Clearance 'C' should be more than 3mm, Engine fully warm, A/C off.
  2. Start engine and set correct warm idle speed (700 in neutral, or 650 RPM in 'D')
  3. Turn A/C ON, in 'N' and adjust engine speed to 800 RPM.
