AWD SYSTEM : System Description
INFOID:0000000009751054
• AWD mode is selectable among 2WD, AWD-V, and AWD by operating the AWD mode switch.
• When judging driving conditions and road surface conditions based on signals transmitted from each sensor
and switch, the AWD system automatically controls torque distribution of front and rear wheels and both
front wheels, depending on the situation.
• In accordance with fail-safe function, when system is malfunctioning, AWD control stops, and the system
becomes front wheel drive. Refer to
DLN-18, "AWD SYSTEM : Fail-safe"
.
• When a high load status continues for electric controlled coupling, AWD control temporarily becomes front
wheel drive, according to protection function. Refer to
DLN-20, "AWD SYSTEM : Protection Function"
AWD SYSTEM : Torque Split Control
INFOID:0000000009751055
2WD mode
• Vehicle is in front-wheel drive.
AWD-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 (AWD) to
have an optimized torque distribution adapted to road condition change.
• When slip occurs on front wheel, distribute optimum torque to rear wheel and keep stable driving.
• On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close to
front-wheel drive and it results in better fuel efficiency.
Cornering Control
• Torque between both rear wheels is automatically changed between 100 : 0 and 0 : 100 for distributing opti-
mum torque that depends on the driving conditions and road surface conditions.
• Producing a difference between both rear wheels enables sporty and smooth handling.
Combination meter
Mainly transmits the following signals via CAN communication line to AWD control
module.
• Parking brake switch signal
Mainly receives the following signals via CAN communication line from AWD control
module.
• AWD warning lamp signal
• AWD mode indicator lamp signal
• Torque distribution indicator signal
Steering angle sensor
Mainly transmits the following signals via CAN communication line to AWD control
module.
• Steering angle sensor signal

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

AWD SYSTEM : Protection Function
INFOID:0000000009751057
AWD system activates its protection function (shuts down AWD system temporarily) if AWD system detects
high load continuously, the front wheel tire size differs from the rear tire size or the rear right wheel tire size dif-
fers from the rear left tire size. (AWD system is automatically restored if AWD 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 OFF)
*2: 1 time/2 seconds (continuing to blink until ignition switch is turned OFF)
NOTE:
• 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.

AWD CONTROL MODULE
Protection Function
INFOID:0000000009751061
AWD system activates its protection function (shuts down AWD system temporarily) if AWD system detects
high load continuously, the front wheel tire size differs from the rear tire size or the rear right wheel tire size dif-
fers from the rear left tire size. (AWD system is automatically restored if AWD 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 OFF)
*2: 1 time/2 seconds (continuing to blink until ignition switch is turned OFF)
NOTE:
• 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.
