AWD models

FUNCTIONS WITHIN THE SYSTEM 

All Wheel Drive function.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM 

AWD Control Unit 

• AWD control unit controls driving force distribution by signals from each sensor from rear wheel driving mode (0:100) to 4-wheel driving mode (50:50).

• Rear wheel driving conditions is available by fail-safe function if malfunction is detected in AWD system.

AWD actuator relay is integrated with AWD control unit, and supplies AWD solenoid with voltage.

Electric Controlled Coupling 

Electric controlled coupling is installed in transfer and transmits driving force to front final drive. For operation, Refer to Structure and Operation .
