ABSTRACT:
A control system for a damping force coefficient of a shock absorber for a vehicle suspension provides a controller for correcting the position of a step motor. The controller sets the step motor at a predetermined position in a manner to intermittently move the step motor to a stop position restricted by a stopper and to reversely rotate it by a predetermined number of steps. Therefore, the step motor is precisely set at a home position without using a position detector.
