35C-96

CAUTION

When the hydraulic unit (integrated with ASC-ECU) is replaced, after turning the ignition switch ON or 
OFF (vehicle information from ETACS-ECU is registered), always carry out the calibration of all sen-
sors (steering wheel sensor, G and yaw rate sensor, and brake fluid pressure sensor) at one time.( 
Refer to 

P.35C-93

.)

Pre-removal operation
• Brake fluid draining.

Post-installation operation
• Brake fluid refilling and air bleeding (Refer to GROUP 35A 

− On-vehicle Service, Bleeding ).

• Hydraulic unit check (Refer to 

P.35C-90

).

REMOVAL

CAUTION

• Be careful when removing the hydraulic unit 

because it is heavy.

• Never loosen the nuts and the bolts because 

the hydraulic unit cannot be disassembled.

• Do not drop or shock the hydraulic unit.
• Do not turn the hydraulic unit upside down or 

lay down the unit because the inner air 
becomes difficult to be bled.

STEERING WHEEL SENSOR

REMOVAL AND INSTALLATION

M1355005100726

CAUTION

• Be sure to remove the clock spring from the column switch and centre the clock spring to prevent 

the damage of steering wheel sensor.

• If the centre of the clock spring is not correctly aligned, the steering wheel may not be turned fully 

or the cable inside the clock spring may be broken, causing the SRS air bag to be inoperative or 
operated incorrectly.

• Before removing the steering wheel/air bag module assembly, refer to GROUP 52B − Service Pre-

cautions  and Air Bag Module Clock Spring .

• When the steering wheel sensor is replaced or installed, always carry out calibration to make 

ASC-ECU learn the neutral point (Refer to 

P.35C-94

).

• After adjusting the wheel alignment, always carry out calibration of the steering wheel sensor to 

make ASC-ECU learn the neutral point. (Refer to 

P.35C-94

.)

Pre-removal operation
• Position the front wheels in a straight ahead direction.

Post-installation operation
• Perform steering wheel sensor calibration (Refer to 

P.35C-94

).

REMOVAL

Disengage the claws of the clock spring one by one 
in a clockwise or anti-clockwise direction. Remove 
the steering wheel sensor from the clock spring.

INSTALLATION SERVICE POINT

>>A<< STEERING WHEEL SENSOR 
INSTALLATION

CAUTION

Install the steering wheel sensor with its rotat-

ing part removed. If the rotating part is rotated 
360

°, a failure occurs in calibration and ASC sys-

tem.
Insert the protrusion of the clock spring into the hole 
of the steering wheel sensor. Securely fit the protru-
sion of the steering wheel sensor into the groove of 
the clock spring to install the steering sensor.

NOTE: A new steering wheel sensor has a pin for 
preventing the rotation of (fixing) the steering wheel 
sensor. After installing the column switch assembly, 
remove this pin.
