NG: ELECTRONIC 4WD CONTROL SYSTEM
Electronic AWD Control System Outline
• The newly adopted electronic AWD control system automatically and optimally controls drive torque distribution
for the front and rear wheels. Due to this off-road mobility and driving stability are improved.
• Based on the input signals from each sensor, the AWD control module (AWD CM) determines vehicle driving
and road conditions, and controls output current to the electronic control coupling (AWD solenoid) inside the
rear differential. This control allows for optimal distribution of the drive torque from the engine to the rear
wheels.
• Also, the AWD CM automatically controls the AWD, greatly reducing the load on the driver and improving
operability.
