there is a high and low setting in the power steering

now low is for under 80km/hr and high is for over 80km/hr

the high setting is where 4ws kicks in. the steering is also heavier than on the low setting

when the steering wheel moves more than 20 deg. (correct me on this one guys) either way the rear wheels flick in the opposite direction 1 deg until the steering wheel is returned to lower than the 20 deg set by nissan

if im wrong here will anyone correct me on it

HICAS is Nissan’s version of four wheel steering. It is an acronym for High Capacity Actively Controlled Suspension. Unlike other Japanese car manufacturers 4WS (eg Honda’s system) HICAS never exceeds +/- 1°. It is designed for high speed response rather than parking manoeuvres.

The system is electro-hydraulic - the ECU in the boot directs a hydraulic actuator at the rear axle to steer the rear wheels using the rearmost suspension links. The result is usually no more than 0.4° of movement. HICAS gives a touch of counter steer before settling with the rear wheel pointing the same way as the front. (Maybe this explains why my Skyline feels so loose on high-speed gravel...) This results in sharp turn-in, and enhanced stability at medium to high speeds.
