Control-Track® Function
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The Control-Track® transfer case uses an electromechanical clutch assembly to control the torque to the front wheels. In Auto mode, while at rest and under cruising conditions, the 4WD control module activates the transfer case clutch at a minimum level. This allows for the slight difference between the front and rear driveshafts which occurs normally when negotiating a corner on dry pavement. Under any of the following conditions, the 4WD control module will increase the torque sent through the clutch to the front wheels in order to prevent or control slip.
NOTE:
At zero throttle, the duty cycle remains low.
