The transfer case transfers power from the transmission to the rear axle and front axle only when the electromechanical clutch is activated.
The electromechanical clutch assembly drives the drive sprocket after the 4x4 electronic module activates the clutch coil. The drive sprocket turns the drive chain that rotates the front output shaft and the front driveshaft.
