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.
