COMBINED SENSOR FUNCTION
id041800819800
• A combined sensor, which integrates the yaw rate, roll rate, forward-G and lateral-G sensors, has been
adopted.
• The combined sensor, located in the floor under the Second-row seat (RH), detects the vehicle yaw rate
(vehicle turning angular speed), roll rate (vehicle rolling angular speed), forward-G and lateral-G, and transmits
them to the dynamic stability control (DSC)/roll stability control (RSC) hydraulic unit (HU)/control module (CM).

COMBINED SENSOR CONSTRUCTION/OPERATION
id041800819900
• The combined sensor, which integrates the yaw rate, roll rate, forward-G and lateral-G sensors, detects and
calculates the vehicle yaw rate, roll rate, forward-G and lateral-G, and transmits this to the dynamic stability
control (DSC)/roll stability control (RSC) hydraulic unit (HU)/control module (CM) via special controller area
network (CAN) lines between the sensor and module.
• The yaw rate and roll rate sensor detects a Coriolis force created by, and in proportion to, the rotation speed of
a gyroscope.
• The forward-G and lateral-G sensor detects an inertial force created by, and in proportion to, a G-force acting
on a silicon detection component.
Note
• Coriolis force: When an object on a rotating
disc attempts to move toward the center of
the disc, force is produced at a right angle to
the intended path of travel of the object. This
results in the direction of movement being
unchanged from its original point of
departure, and the object does not reach the
center. When looking at this effect from
outside the disc, it appears as if a force is
deflecting the object away from the center.
This appearance of force is called a Coriolis
force, and the object actually advances in a
straight course.

BRAKE FLUID PRESSURE SENSOR FUNCTION

• The brake fluid pressure sensor detects the fluid pressure from the master cylinder and transmits it to the
dynamic stability control (DSC)/roll stability control (RSC) hydraulic unit (HU)/control module (CM).

BRAKE FLUID PRESSURE SENSOR CONSTRUCTION
id041800102100
• The brake fluid pressure sensor is integrated with the dynamic stability control (DSC)/roll stability control (RSC)
hydraulic unit (HU)/control module (CM). Therefore if there is any malfunction of the brake fluid pressure
sensor, replace the DSC/RSC HU/CM.
