• Based on the inputted signals listed below, the 4WD CM calculates the optimal amount of torque distribution for the rear wheels and outputs a corresponding electric control current to the electronic control coupling (4WD solenoid).
• The module controls the current outputted to the 4WD solenoid by changing the rate of the ON/OFF timing.

Signal output part | Signal name | Note
--- | --- | ---
PCM | Accelerator pedal position Engine speed | Transmitted as a CAN signal
TCM | Selector lever position Gear position
DSC HU/CM | Four-wheel speed DSC operating condition Coupling torque request (DSC equipped vehicles)
Differential oil temperature sensor | Rear differential oil temperature | -
