Features

• Based on the inputted signals listed below, the 4-wheel drive (4WD) control module (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.
