The wheel speed sensor is a kind of a pulse generator. It consists of the magnetic encoder
for wheel speed detection (a plate on which north and south pole sides of the magnets are arranged
alternately) which rotates at the same speed of the wheel and the wheel speed sensor (semiconductor
sensor). This sensor outputs frequency pulse signals in proportion to the wheel speed.

The front wheel speed sensor consists of the front wheel speed sensor mounted on the knuckle
and the magnetic encoder for wheel speed detection which is press-fitted together with the oil
seal to the front wheel bearing. The rear wheel speed sensor consists of the rear wheel speed
sensor mounted on the trailing arm assembly and the magnetic encoder for wheel speed detection
which is press-fitted together with the oil seal to the rear wheel bearing.

The G and yaw rate sensor is installed under the front seat <LH side>, and detects
the yaw rate and lateral acceleration of the vehicle.
|
|
The steering wheel sensor is attached to the column switch, and detects the rotational
angle of the steering wheel.

|
The ASC OFF switch is attached on the instrument panel to the left side <LHD> or
right side <RHD> of the driver’s seat. TCL and stability control
functions can be disabled by pressing this switch for 3 seconds. Pressing this switch again
resumes the "ON" status. As a countermeasure for the stuck of the ASC OFF switch, pressing the
ASC OFF switch for 15 seconds resumes the system to the "ON" status.
When the electric motor switch is turned from "LOCK" to "ON" position, TCL and stability
control functions are constantly in the "ON" status.
