Transfer Case - INGENIUM I4 2.0L Diesel/INGENIUM I4 2.0L Petrol/TDV6 3.0L Diesel/V6 S/C 3.0L Petrol: Operation: Notes

The Transfer Case Control Module (TCCM) is connected to the:

• High Speed (HS) Controller Area Network (CAN) chassis systems bus, and
• High Speed (HS) Controller Area Network (CAN) powertrain systems bus.

The TCCM receives data from various control modules including the PCM (Powertrain Control Module) and the ABS (Anti-lock Brake System) control module. Using this information the TCCM determines the required torque to be applied to the front wheels via an electro-hydraulic controlled clutch and chain gear drive to the front driveshaft.

There are 2 stages of operation the first stage is a pre-emptive stage. In this stage, the vehicle systems are evaluating road surface conditions and assessing the level of traction.

Once the level of traction is understood, the system moves into a second stage of control. This is where an optimum front to rear torque split is determined, based on vehicle speed and cornering conditions.

The TCCM also features a reactive feedback loop to increase torque to the front axle if traction is lost and slip occurs. The TCCM works in conjunction with the:

• Dynamic Stability Control (DSC)
• Electronic Traction Control (ETC)
• and Anti-lock Brake (ABS) systems to maintain the vehicle's traction and stability.

Torque on Demand Benefits:

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