ELECTRIC CONTROLLED COUPLING
1. The AWD control unit supplies command current to electric con-
trolled coupling (AWD solenoid).
2. The control clutch is engaged by electromagnet and torque is
detected in control clutch.
3. The cam operates in response to control clutch torque and
applies pressure to main clutch.
4. The main clutch transmits torque to front wheels according to
pressing power.
• Transmission torque to the rear wheels is determined accord-
ing to command current.

DESCRIPTION
• AWD controls distribution of drive power between front-wheel drive (100:0) and 4-wheel drive (50:50) condi-
tions according to signals from sensors.
• By receiving the steering angle sensor signal, yaw rate sensor signal, side G sensor signal and decel G sen-
sor signal, vehicle with VDC corrects a torque distribution for front and rear wheels according to a driving
operation and a behavior of the vehicle during cornering and improves drivability and safety on a slippery
road surface.
• Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
• AWD mode makes possible stable driving possible with no wheel spin, on snowy roads or other slippery sur-
faces.
• On roads which do not require 4-wheel drive, it contributes to improved fuel economy by driving in conditions
close to front-wheel drive.
• Sensor inputs determine the vehicle's turning condition, and tight cornering/braking are controlled by distrib-
uting optimum torque to rear wheels.
NOTE:
Light tight-corner braking symptom may occur depending on driving condition. This is not malfunction.
AWD SYSTEM : Fail-Safe
INFOID:0000000011278299
If any malfunction occurs in AWD electrical system, and control unit detects the malfunction, AWD warning on
information display (combination meter) is displayed to indicate system malfunction. And then AWD control
unit controls becomes the fail-safe mode depending on DTC.
AWD SYSTEM : Protection Function
INFOID:0000000011278300
AWD system activates its protection function (shuts down AWD system temporarily) if AWD system detects
high load continuously or the front wheel tire size differs from the rear tire size. (AWD system is automatically
restored if AWD system no longer detects any overload or the tire size difference is eliminated.)
ABS actuator and electric unit (control unit)
Mainly transmits the following signals to AWD control unit via CAN
communication:
• Each wheel speed signal
• Stop lamp switch signal (brake signal)
• Yaw rate sensor signal
• Side G sensor signal
• Decel G sensor signal
ECM
Mainly transmits the following signals to AWD control unit via CAN
communication:
• Accelerator pedal position signal
• Engine speed signal

Vehicle condition
•C1201
•C1204
•C1209
•P1804
•P1809
•P1811
•P181F
AWD control changes to front-wheel drive immediately, then AWD control stops, and the vehicle
becomes front-wheel drive.
•C1203
•C1210
•P1808
•P181D
•U1000
•U1010
AWD control changes to front-wheel drive gradually (rear-wheels still have some driving torque),
then AWD control stops, and the vehicle becomes front-wheel drive.
•P181B
No impact to vehicle behavior.
