ALL MODE 4X4 SYSTEM
4WD MODE SWITCT
AUTO mode (AUTO indicator lamp ON)
lElectronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
lMakes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
lOn roads which do not require 4WD, it contributes to improved fuel economy by driving in conditions close
to front-wheel drive.
lSensors determine the vehicle's turning condition, and in response tight cornering/braking are controlled
by distributing optimum torque to rear wheels.
NOTE:
lWhen driving in AUTO mode or LOCK mode, if there is a large difference between front and rear wheel
speed which continues for a long time, oil temperature of drive system parts becomes too high and 4WD
warning lamp flashes rapidly. (When 4WD warning lamp flashes, vehicle changes to front-wheel drive
conditions.)
lWhen driving in AUTO mode, 4WD warning lamp may flash slowly if there is a significant difference in
pressure or wear between tires. At this time, vehicle performance is not fully available and cautious driving
is required. (Continues until engine is turned OFF.)
lIf 4WD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AUTO mode will be restored.
lIf 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.
lWhen the difference of revolution speed between the front and rear wheel with AUTO mode the shift
switch occasionally changes to LOCK mode automatically. This is not malfunction.
LOCK mode (LOCK indicator lamp and AUTO indicator lamp ON)
lFront/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes.
lWhen LOCK mode is selected, vehicle will switch automatically to AUTO mode if vehicle speed increases.
If vehicle speed then decreases, the vehicle automatically returns to direct 4-wheel driving conditions.
NOTE:
If there is a significant difference in pressure or wear between tires, full vehicle performance is not available.
Tire conditions are detected, and LOCK mode may be prohibited, or else speeds at which LOCK mode is
enabled may be restricted.
2WD mode (indicator lamps OFF)
Vehicle is in front-wheel drive.
NOTE:
lIf front wheels are slipping in 2WD mode, do not switch to AUTO or LOCK. This can cause difficulties for
the system.
lThe shift switch even if the shift switch is in 2WD mode, the sift switch occasionally automatically change
to 4WD mode depending on the driving condition (For example; Depressing the acceleration firmly). this is
not malfunction. How ever, 4WD mode indicator lamp dose not illuminate.
4WD WARNING LAMP
Turns ON when there is a malfunction in 4WD system. It indicates that fail-safe mode is engaged and vehicle
is in 2WD.
Also turns ON when ignition switch is turned ON, for purpose of bulb check. Turns OFF approximately for 3
seconds after the engine starts if system is normal.

FAIL- SAFE FUNCTION
lIf a malfunction occurs in 4WD electrical system, and control unit detects the malfunction, 4WD warning
lamp on gauge turns ON to inform driver of system malfunction.
lWhen 4WD warning lamp is ON, vehicle is in 2WD.

SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
