OUTLINE
Features
Improved off-road mobility, handling stability, operability, fuel economy and marketability
• An electronic 4WD control system, which automatically optimizes traction distribution to the front and rear
wheels, has been adopted.
Improved serviceability
• A self-diagnostic function has been adopted for the electronic 4WD control system.
Electronic 4WD control system outline
• The newly adopted electronic 4WD control system automatically and optimally controls drive torque distribution
for the front and rear wheels. Due to this off-road mobility, driving stability and fuel economy are improved.
• Based on the input signals from each sensor, the 4WD control modure (4WD CM) determines vehicle driving
and road conditions, and controls output current to the electronic control coupling (4WD solenoid) inside the
rear differential. This control allows for optimal distribution of the drive torque from the engine to the rear
wheels.
• Also, the 4WD CM automatically controls the 4WD, greatly reducing the load on the driver and improving
operability.
