PROBLEM SYMPTOMS TABLE
HINT:
• Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms
are listed in order of probability in the "Suspected area"
column of the table. Check each symptom by checking the
suspected areas in the order they are listed. Replace parts
as necessary.
• The Matrix Chart is divided into 2 chapters. When
troubleshooting, check Chapter 1 first. If instructions are
given in Chapter 1 to proceed to 2, proceed as instructed.
• If the instruction "Proceed to next circuit inspection shown
in problem symptoms table" is given in the flowchart for
each circuit, proceed to the next suspected area in the
table.
• If the problem still occurs even though there are no
malfunctions in any of the circuits, check the ECM and
replace it if necessary.

TF–6GF1A TRANSFER – ACTIVE TORQUE CONTROL 4WD SYSTEM
TF
SYSTEM DESCRIPTION
1. GENERAL DESCRIPTION
(a) The active torque control 4WD system detects the
driving conditions based on signals from each ECU,
each switch, the steering angle sensor, the wheel
speed sensor, and the yaw rate sensor. The system
controls the electronic current passing through the
linear solenoid of the electromagnetic coupling, and
performs electronic control to distribute the optimum
torque to the rear wheels.
(b) Main components and their functions.
C128585E01
Component Function
4WD Indicator Light Displays warning to driver when system malfunctions
Stop Light Switch Detects brake operation
Throttle Position Sensor Detects opening angle of throttle
Park/Neutral Position Switch Detects "P" position
Steering Angle Sensor Detects turning of steering wheel
4WD Linear Solenoid Detects electronic control limiting clutch operation using signals from
4WD control ECU
Skid Control ECU with Actuator Detects signals from each sensor and outputs them to 4WD control
ECU
4WD Control ECU Detects signals from each sensor via skid control ECU to operate
linear solenoid and control system
Crankshaft Position Sensor Detects engine rpm and inputs it into ECM
Yaw Rate Sensor Detects forward and rearward acceleration of vehicle, and inputs it into
skid control ECU
