Current revision
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.

[edit]
Overview
FICD consists of two parts, a throttle actuator, and a vacuum switch. The switch is either magnetically electrically operated off the compressor. The switch then lets vacuum go to the actuator, which pulls the carburetor throttle lever a little (about 100 RPM).
[edit]
Magnetic Switch
The magnetic switch is on the side of the compressor, and opens when the compressor activates.
When the switch lets vacuum pass, the vacuum pulls up the diaphragm which lifts the throttle lever on the side of the carburetor.
[edit]
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

Sunny Truck
From 1978-1989, no special idle control device was used. For 1990-1994 they added FICD to the A12 engine.
