Transfer Case - V8 S/C 5.0L Petrol: Operation: Notes

The Transfer Case Control Module (TCCM) is electrically connected to the High Speed (HS) Controller Area Network (CAN) chassis systems bus.

The TCCM contains the Intelligent Driveline Dynamics (IDD) software. The IDD system monitors the vehicle behavior, driver input and road surface conditions every 10 milliseconds. The IDD system optimizes torque distribution to deliver maximum traction performance, stability and yaw control.

The IDD system comprises a torque distribution controller based on driver demanded torque, lateral acceleration and vehicle speed. The IDD system is configured to give the desired on-power handling balance. A traction controller responds to slip between the front and rear differentials for maximum traction performance. The system also has an intelligent yaw controller which continuously monitors the yaw behavior of the vehicle. The IDD system responds to on-power oversteer conditions by transferring torque from the rear differential to the front differential to stabilize the vehicle.

The TCCM also features a reactive feedback loop to increase torque to the front differential if traction is lost and slip occurs. The TCCM works in conjunction with the Anti-lock Brake System (ABS) control module.

Torque on demand benefits:

• Full traction capability when required.
• Supports a wide range of vehicle handling characteristics.
