Verify that the vehicle's wheel alignment is correctly set. A misalignment can affect sensor readings.
If misalignment is found, use a wheel alignment machine to adjust to manufacturer specifications.

4. Steering Angle Sensor Calibration

Reconnect the battery and start the vehicle.
Use the diagnostic tool to navigate to the steering angle sensor calibration menu.
Follow on-screen instructions to calibrate the steering angle sensor. This may involve turning the steering wheel fully left and right.

5. Software Update

Check the vehicle's software version against the latest available from Volvo.
If an update is available, connect the vehicle to a compatible diagnostic tool and follow the prompts to update the software.

6. Test the System

After repairs, perform a test drive to check the functionality of the lane keeping assist system.
Ensure the system engages properly and that the vehicle maintains its lane without excessive corrections.
