AWD SYSTEMPFP:41650
Power Transfer DiagramNDS000DB
System DescriptionNDS000DC
DESCRIPTION
Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close
to rear-wheel drive.
Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
NOTE:
When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becomes too high and AWD warning lamp flashes rapidly.
(When AWD warning lamp flashes, vehicle changes to rear-wheel drive conditions.) Also, optional distri-
bution of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.
If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AWD system will be restored.
When driving, AWD warning lamp may flash slowly if there is a significant difference in diameter of the
tires. At this time, vehicle performance is not fully available and cautious driving is required. (Continues
until engine is turned OFF.)
If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.
When the difference of revolution speed between the front and rear wheel the shift occasionally changes
to direct 4-wheel driving conditions automatically. This is not malfunction.

AWD WARNING LAMP
Turns ON when there is a malfunction in AWD system. It indicates that fail-safe mode is engaged and vehicle
change to rear-wheel drive or shifting driving force-AWD (Front-wheels still have some driving torque).
Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1
seconds after the engine starts if system is normal.
AWD Warning Lamp Indication

Condition AWD warning lamp
Lamp checkTurns ON when ignition switch is turned ON. Turns OFF
approx. 1 second after engine start.
AWD system malfunctionON
Protection function is activated due to heavy load to electric con-
trolled coupling. (AWD system is not malfunctioning and AWD system
changes to 2WD mode.)Rapid flashing: 2 times/second
(Flashing in approx. 1 minute and then turning OFF)
Large difference in diameter of front/rear tiresSlow flashing: 1 time/2 seconds
(Continuing to flash until turning ignition switch OFF)
Other than above (system normal) OFF

Transmitter Wake Up OperationNES000JZ
WITH TRANSMITTER ACTIVATION TOOL
1. With the activation tool [SST: J-45295] pushed against the front-
left transmitter, press and hold the button for 5 seconds.
When ignition switch ON, as the low tire pressure warning
lamp blinks per the follow diagram, the respective transmitter
then must be woken up.
2. Register the ID of wheel that warning lamp flashes. When wake up of registered wheel has been com-
pleted, turn signal lamp flashes two times.
3. After completing wake up all transmitters, make sure low tire pressure warning lamp goes out.
