STEERING ANGLE SENSOR INITIALIZATION PROCEDURE

WARNING:
- If the steering angle sensor reference point setting is not completed, it could result in an unexpected accident due to the related systems being inoperative. Therefore, if the BCM connector or negative battery cable are disconnected, or the BCM power supply is interrupted, always perform the steering angle sensor reference point setting and verify that each system is operational.

NOTE:
- The BCM stores the steering angle reference point using battery power supply. Therefore, if the following operations are performed and the power supply to the BCM is interrupted, the stored steering angle reference point will be erased.

- The negative battery cable is disconnected
- The steering angle sensor connector is disconnected
- A fuse (ROOM) is removed
- The wiring harness between the BCM and steering angle sensor connector is disconnected

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. Start the engine.

3. Confirm that the AFS OFF light illuminates and that the AFS OFF light flashes. (with AFS (Adaptive front lighting system))

4. Turn the steering wheel to full right lock, then turn it to full left lock.

NOTE:
- The steering wheel can be turned first to the left or right.
- If the steering wheel is turned in the opposite direction before it locks, the correct steering angle will not be stored in memory.

5. Confirm that the AFS OFF light and AFS OFF light goes out. (with AFS (Adaptive front lighting system))

- If the AFS OFF light does not go out, disconnect the negative battery cable, and perform the procedure again starting from Step 2 shown above.

6. Drive the vehicle for approx. 10 min, and confirm that the AFS OFF lights do not illuminate. (with AFS (Adaptive front lighting system))
