Steering Angle Sensor: Service and Repair
REMOVAL AND INSTALLATION
CAUTION:
- Be sure to remove the clock spring from the column switch and center the clock spring to prevent the damage of steering wheel sensor.
- If the center 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 Service Precautions Service Precautions and Driver's Air Bag Module Clock Spring Driver's Air Bag Module and Clock Spring Removal and Installation (Except Ralliart) [Except RALLIART], Driver's Air Bag Module and Clock Spring Removal and Installation (Ralliart) [RALLIART].
- When the steering wheel sensor is replaced or reinstalled, always carry out calibration to make ASC-ECU learn the neutral point (Refer to Testing and Inspection).

CAUTION:
- Be sure to remove the clock spring from the column switch and center the clock spring to prevent the damage of steering wheel sensor.
- If the center 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.
Align the mating marks of the clock spring.
[Alignment of mating marks]
(1) Turn the clock spring clockwise fully.
(2) Turn the clock spring counterclockwise approximately three and 3/4 turns to align the mating marks.
(3) Install the clock spring to the column switch.
2.
CAUTION:
Always align three mating marks of the steering wheel sensor simultaneously as shown in the figure. If these mating marks are not aligned correctly, the steering wheel sensor may be damaged.
Align three mating marks of the steering wheel sensor simultaneously as shown in the figure.
[Alignment of mating marks]
(1) Check the window for inspecting the neutral position of the steering wheel sensor.
If the mating marks cannot be seen from the window, align the mating marks as shown in the figure.
(2) Install the steering wheel sensor to the column switch assembly, maintaining the neutral position correctly.
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.
(3) Install the column switch assembly to the vehicle, maintaining the neutral position correctly.
