*: Drive at such a speed in the uppermost gear to engage
lock-up. The vehicle can be driven at a speed lower than the
speed shown in the above diagram under the lock-up
condition.
NOTICE:
It is necessary to drive the vehicle for approximately 30
minutes to detect DTC P0711 (Transmission fluid
temperature sensor "A" performance).

DESCRIPTION
If a malfunction in the power source circuit occurs, or a malfunction in communication with the skid control
ECU or in a speed sensor occurs, the 4WD control ECU will prohibit operations by the fail-safe function.

INSPECTION PROCEDURE
HINT:
Check the condition of each related circuit connector before troubleshooting (see page IN-37).
DTC C1241/94 Low Power Supply Voltage
DTC No. DTC Detection Condition Trouble Area
C1241/94 When one of following conditions is met:
1. When following continues for 10 seconds
or more:
- At a vehicle speed of 3 km/h (2 mph) or
more, voltage of IG1 terminal is 9.5 V or
less.
2. When both of following continue for 60
seconds or more:
- With the voltage of IG1 terminal 9.5 V or
less, communication with the skid control
ECU cannot be performed.
- A malfunction in communication with
skid control ECU.
3. When following continue for 3 seconds or
more:
- With the voltage of IG1 terminal 9.5 V or
more, communication with the skid control
ECU cannot be performed.•Battery

C128626E02

TF–30GF1A TRANSFER – ACTIVE TORQUE CONTROL 4WD SYSTEM
TF
DESCRIPTION
• The 4WD control ECU determines that the vehicle is turning based on the signals sent from the
steering angle sensor.
• The steering angle sensor signal is sent to the 4WD control ECU via the CAN communication system.
• The 4WD control ECU detects the amount of steering wheel movement and performs "slip control at
vehicle start up", according to the amount of movement, and "slip control" to secure high turning
performance.
WIRING DIAGRAM
INSPECTION PROCEDURE
HINT:
Check the condition of each related circuit connector before troubleshooting (see page IN-37).
(a) Clear the DTC (see page TF-16).
(b) Turn the ignition switch OFF.
(c) Turn the ignition switch ON again and check that no CAN
communication system DTC(s) is output.
(d) Start the engine.
DTC C1297/97 Steering Angle Sensor
DTC No. DTC Detection Condition Trouble Area
C1297/97 When voltage of 4WD control ECU IG1
terminal is 9.5 V or more, and steering angle
sensor malfunction signal is received.• Steering angle sensor
• CAN communication
• 4WD control ECU
• Wire harness

C128601E02

GF1A TRANSFER – ACTIVE TORQUE CONTROL 4WD SYSTEMTF–33
TF
DESCRIPTION
The 4WD control ECU receives signals from each sensor to control clutch fluid pressure for limiting the
center differential operation, which distributes torque according to the driving conditions.
