4WD Control Unit

INFOID:0000000009177707

• Controls driving force distribution by signals from each sensor from front wheel driving mode (100:0) to 4-

wheel driving mode (50:50).

• Front wheel driving conditions is available by fail-safe function if malfunction is detected in 4WD system.

• 4WD actuator relay is integrated with 4WD control unit, and supplies 4WD solenoid with voltage. 

4WD Solenoid

INFOID:0000000009177708

Controls electric controlled coupling by command current from 4WD control unit.

Electric Controlled Coupling

INFOID:0000000009177709

Electric controlled coupling is integrated with rear final drive and transmits driving force to rear final drive. For

operation, refer to 

DLN-13, "Operation Description"

.

4WD Shift Switch

INFOID:0000000009177710

Every time 4WD shift switch is pressed, AUTO mode, 2WD mode and LOCK mode switch each other. 

Vehicle Information Display

INFOID:0000000009177711

4WD MODE INDICATOR

4WD mode indicator displays the state of the 4WD mode.

TORQUE DISTRIBUTION INDICATOR

The number of bars shows driving force distributed to each tire.

NOTE:

The driving force distribution may not match actual one. This is not a system malfunction.

4WD WARNING INDICATOR

4WD warning indicator is displayed when there is a malfunction in 4WD system. 4WD warning indicator indi-

cates the vehicle is in fail-safe mode and shifting to front-wheel drive or 4-wheel drive (rear-wheels still have

some driving torque).

6

Steering angle sensor

Transmits/receives the signals for control of 4WD system via CAN com-
munication line to/from 4WD control unit. For transmitting/receiving mainly 
signals, refer to 

DLN-15, "4WD SYSTEM : System Description"

.

Refer to 

STC-4, "Component Parts Location"

 for detailed installation loca-

tion.

CAUTION:

• 4WD warning indicator is displayed due to data reception error, CAN communication error etc.

Condition

4WD warning indicator

4WD system malfunction

(Indicator lamp illuminates)

Protection function is activated due to heavy load to electric con-
trolled coupling. (4WD system is not malfunctioning and 4WD sys-
tem changes to front wheel drive.)
When this indication is displayed, refer to 

DLN-67, "Description"

.

(Indicator lamp blinks rapidly)

Large difference in diameter of front/rear tires
When this indication is displayed, refer to
