STEERING ANGLE SENSOR INITIALIZATION PROCEDURE
WARNING:
Unless the initialization procedure of the steering angle sensor is completed, the DSC will
not operate, causing an unexpected accident. Therefore, always perform the initialization
procedure to ensure DSC operation if the power supply to the steering angle sensor has
been cut off due to disconnection of the steering angle sensor connector or negative
battery cable, or any other cause.
NOTE:
The steering angle sensor requires battery power to store the steering angle initial
position. Therefore when the battery power supply is cut off, a stored steering angle initial
position is cleared.
1. Inspect the wheel alignment, inflation pressure, and the installation condition of the steering
wheel.
If there is any malfunction, adjust the applicable part.
2. Connect the negative battery cable.
3. Turn the ignition switch to the ON position.
4. Confirm that the DSC indicator light illuminates and that the DSC OFF light flashes.
5. Turn the steering wheel to full right lock, then turn it to full left lock.
6. Confirm that the DSC OFF light goes out.
7. Turn the ignition switch off.
8. Turn the ignition switch to the ON position again, and confirm that the DSC indicator light
goes out.
If the DSC indicator light does not go out, disconnect the negative battery
cable, and perform the procedure again starting from Step 2 shown above.
9. Drive the vehicle at a speed of 20 km/h {13 mph} or more for 60 s or more, then verify
that the ABS warning light and DSC indicator light do not illuminate.
