GENERAL INFORMATION
OVERVIEW
In traditional constant power assist steering system, the steerability gets lighter as vehicle speed rises, and this may
cause dangerous situation. Where as having heavy steerability in high speed driving makes it difficult to manipulate the
steering wheel when vehicle is in stop. This steering system solve this problem as the steerability is changed according
to the vehicle speed, which is called Speed Sensitive Power Steering (SSPS).
SSPS, by providing appropriate steerability to driver according to the changes of vehicle speed, gives steering stability.
In other words, the steering wheel gets lighter by adjusting steerability in stop or low speed and provides steering
stability by adjusting steering wheel to become heavier in high speed.
SSPS system applied in Rexton is ECPS (Electronic Control Power Steering: Hydraulic Pressure Reaction Force
Control) type that allows to change the steerability according to the vehicle speed. The power steering control unit
adjusts the hydraulic pressure to reaction plunger by controlling the pressure solenoid valve located in gear box to
optimize the steerability.

Notice
It is not easy to locate the ECPS system solenoid valve (2) at correct position when replacing it. Thus, even
though the fault is only in the solenoid valve, you must replace the power steering assembly. Be careful
not to damage the solenoid valve during storage and shipment.
