Claim:
1. A method, comprising: receiving a displacement signal generated by a sensor, the displacement signal generated by the sensor in response to detecting movement of a piston from a retracted position in a cylinder toward an extended position in the cylinder; generating, in response to receiving the displacement signal, a first valve control signal to be communicated to a first valve located on a first vacuum line connecting a vacuum source to a vacuum port of the cylinder, the first valve control signal causing the first valve to move from a first position in which a vacuum pressure is applied to the cylinder via the vacuum port to a second position in which atmospheric pressure is applied to the cylinder via the vacuum port; and generating, in response to receiving the displacement signal, a second valve control signal to be communicated to a second valve located on a second vacuum line connecting the vacuum source to a cluster control valve, the second valve control signal causing the second valve to move from a second position in which atmospheric pressure is supplied to the second vacuum line to a first position in which a vacuum pressure is supplied to the second vacuum line.
