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
- Clearance 'C' should be more than 3mm, Engine fully warm, A/C off.
- Start engine and set correct warm idle speed (700 in neutral, or 650 RPM in 'D')
- Turn A/C ON, in 'N' and adjust engine speed to 800 RPM.
- FICD adjusting screw
- Lever 'A'
- Lever 'B'
- Cable lock screw
