System Description
Construction and Function (cont'd)
Fail-Safe Function
If the control unit detects an abnormality, it shuts the
traction control system off and causes the TCS indicator
light to come on. However if the abnormality is detected
while the TCS is activated, the control unit first estab-
lishes the appropriate wheel spin velocity, then shuts
the system down, thus preventing excessive wheel spin.
Self-Diagnosis Function
If the control unit detects an abnormality, it records a
Diagnostic Trouble Code (DTC) which can be used to
diagnose the problem. The DTC is shown at the TCS
indicator light when the Service Check connector termi-
nals are connected with the SCS service connector.
Steering Angle Detection
Steering angle is detected by the steering angle sensor,
located on the steering column. The sensor uses two
magneto-resistor (MR) elements to determine steering
angle and direction of rotation. When the driver turns
the steering wheel, a magnet in the steering shaft gener-
ates waves in the "MR" elements. These waves are
amplified and converted into signals which the control
unit can interpret as angle and direction of turn.
Vehicle Speed Detection
Wheel rotation speed is detected by the wheel sensors,
located at each wheel. The signals are sent to the con-
trol unit, which compares each wheel's speed and deter-
mines whether traction control is required.
