Reconnect the vehicle battery.
Use the OBD-II scanner to connect to the vehicle’s ECU.
Check for any available software updates for the lane keeping assist system.
Follow the manufacturer instructions to apply any updates.

4. Alignment and Tire Pressure

Use a tire pressure gauge to check all tire pressures; inflate to manufacturer specifications if necessary.
If alignment is off, take the vehicle to a certified alignment shop to have it properly aligned.

5. Recheck System Functionality

Perform a system reset by disconnecting and reconnecting the battery for a few minutes.
After reconnecting, test the lane keeping assist system in a safe environment to ensure it engages correctly.
