4WD system : System Diagram



It transmits/receives each signal from the following 4WD control module via CAN communication line.

4WD system : System Description

4WD system : System Description

4WD mode is selectable among 2WD, 4WD-V, and 4WD by operating the 4WD mode switch.

When judging driving conditions and road surface conditions based on signals transmitted from each sensor and switch, the 4WD system automatically controls torque distribution of front and rear wheels and both rear wheels, depending on the situation.

In accordance with fail-safe function, when system is malfunctioning, 4WD control stops, and the system becomes rear wheel drive. Refer to DLN-19, "4WD SYSTEM : Fail-safe".

When a high load status continues for electric controlled coupling, 4WD control temporarily becomes rear wheel drive, according to protection function. Refer to DLN-21, "4WD SYSTEM : Protection Function".

4WD system : Torque Split Control

2WD mode
Vehicle is in front-wheel drive.

4WD-V mode
Normal Control
Pressing force of multiple disc clutch is controlled by electric control. Driving torque distribution of front and rear wheels changes automatically between approximately 100 : 0 (Front wheel drive) and 50 : 50 (4WD) to have an optimized torque distribution adapted to road condition change.

When spin occurs on front wheel, distribute optimum torque to rear wheel and keep stable driving.

On roads which do not require 4WD, it contributes to improved fuel economy by driving in conditions close to front-wheel drive and it results in better fuel efficiency.

Cornering Control

Cornering Control
Torque between both rear wheels is automatically changed between 100 : 0 and 0 : 100 for distributing optimum torque that depends on the driving conditions and road surface conditions.

Producing a difference between both rear wheels enables sporty and smooth handling.

The vehicle cornering status is judged according to information from each sensor, and the optimum torque is distributed to rear wheels for preventing tight cornering/braking symptom.

4WD mode

4WD mode
The 4WD mode controls torque for obtaining suitable torque for driving on slippery roads (e.g. snow-covered roads) and provides more stable driving, compared to 4WD-V.

4WD system : Fail-safe

When a system malfunction occurs, the 4WD warning lamp turns ON and the 4WD control becomes 2WD state.

4WD system : Protection Function

4WD system : Protection Function

4WD system activates its protection function (shuts down 4WD system temporarily) if 4WD system detects high load continuously, the front wheel tire size differs from the rear tire size or the rear RH wheel tire size differs from the rear LH tire size. (4WD system is automatically restored if 4WD system no longer detects any overload or the tire size difference is eliminated.)

*1: 2 times/second (blinking for approximately 1 minute and then turned

*1: 2 times/second (blinking for approximately 1 minute and then turned OFF)
*2: 1 time/2 seconds (continuing to blink until ignition switch is turned OFF)


If the warning lamp blinks slowly during driving but remains OFF after the engine is restarted, the system is normal. If it again blinks slowly after driving for some time, vehicle must be inspected.

When there is a difference of revolution speed between the front and rear wheel the shift occasionally changes to direct 4-wheel driving conditions automatically. This is not a malfunction.
