Information:

When the Chassis ECM receives signals from the wheel speed sensors and Inertia Measuring Unit (IMU) of a difference in wheel speeds between the front and rear drive trains, the ECM will call for the Interaxle Differential to lock up, locking the front and rear drive trains together.The ECM energizes the Interaxle Clutch Solenoid Valve sending pressurized oil to the Interaxle Differential Clutch located within the Output Transfer Gear.The Interaxle Differential Clutch may not lock completely. The Interaxle Lock Solenoid Valve is a proportional valve. This proportional valve will lock the front and rear drive trains together proportionally to the extent of "lockup" the ATC system requires.The interaxle differential allows the torque from the transmission planetary to be divided between the front axle and the two rear axles. The front axle receives a smaller proportion of the torque than the center and rear axles. This torque difference prevents excess torque from being transmitted to the front axle. Under normal conditions, lockup clutch (7) is not engaged. 66% of the torque from the transmission is transmitted to the center and rear differentials. 33% of the torque is transmitted to the front differential.When conditions exist, the ECM will send a command to solenoid (19) and engage IAD clutches (7). Engaging the clutch in differential group (D) will lock gear (11) to gear (12). Gear (11) is splined to shaft (17). Under this condition, the front and the rear shafts receive equal torque.Cross Axle Differential (XAD) Lock System

The valve locks the left and right wheels together proportionally to the extent of "lockup" the ATC system requires.The same operation occurs on the center and front axles when the ECM detects a difference in wheel speeds on those axles.The ATC system will partially engage the differential lock clutches on grades above 12%, whether there is a loss of traction or not.
