Honda Prelude 1993 Service Manual page 662

The rear wheels are turned by a motor built into the rear steering actuator. The motor is actived by the power circuit in
the 4WS control unit. The actual steering angle of the rear wheels is detected by the rear main steering angle sensor, and
the rear sub steering angle sensor. The 4WS control unit adjusts the angle according to the difference between the sens-
ed steering angle of the rear wheels and the targeted steering angle of the rear wheels.
