Activation
The control module activates the valve by pulsing it with B+ (300 Hz PWM). The valve is powered from control module pin 14 in the connector that
makes contact directly with the gearbox on the bottom of the control module. The valve is grounded from pin 22. The current varies between 0-
1000mA. The solenoid is normally open and the hydraulic pressure drops as the current increases.
