WHEEL SPEED SENSOR

Refer to GROUP 35B 

− Sensor .

G & YAW RATE SENSOR

The G & yaw rate sensor is integrated in the 
ASC-ECU, and detects the yaw rate and longitudinal 
and lateral acceleration of a vehicle.

STEERING WHEEL SENSOR

The steering wheel sensor is attached to the column 
switch, and detects the rotational angle of the steer-
ing wheel.

ASC OFF SWITCH

The ASC OFF switch is installed on the side air outlet 
(driver’s side). ASC functions can be disabled by 
pressing this switch for 3 seconds (The HSA and BA 
function operates even when the ASC system is 
turned OFF with the ASC OFF switch). Pressing this 
switch again resumes the ON status. As a counter-
measure for the stuck of the ASC OFF switch, press-
ing the ASC OFF switch for 15 seconds resumes the 
system to the ON status.
When the ignition switch is turned from "LOCK" 
(OFF) to ON position, ASC functions are constantly 
in the ON status.

ASC OFF SWITCH OPERATION AND SYSTEM OPERATION

NOTE: The stability control is available when the 
vehicle speed is 15 km/h or more.

ACTUATOR

M2355001200445

HYDRAULIC UNIT

The hydraulic unit incorporates the ABS control and 
ASC control. The cut valve, pressure relief valve, 
suction valve, suction damper, G & yaw rate sensor 
and pressure sensor have been added to the unit for 

the ASC control.

NOTE: For the internal hydraulic circuit of the 
hydraulic unit, refer to 

P.35C-15
