CAUTION

• When centring the clock spring, always remove the clock spring from the column switch in 

advance. Otherwise, the sensor may be damaged.

• 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 

P.52B-5

 and Air Bag Module Clock Spring 

P.52B-145

.

• When the steering wheel sensor is replaced, always carry out calibration to make ASC-ECU learn 

the neutral point. (Refer to 

P.35C-119

.)

Pre-removal operation
• Air bag module assembly and steering wheel assembly 

removal (Refer to GROUP 37 

− Steering Wheel 

P.37-90

.)

Post-installation operation
• Airbag module assembly and steering wheel assembly 

installation (Refer to GROUP 37 

− Steering Wheel 

P.37-90

.)

• Perform steering wheel calibration. (Refer to 

P.35C-119

.)
