Solution

1. Preparation

Gather tools such as an OBD-II scanner and a flathead screwdriver.
Ensure the vehicle is in a safe location with the ignition turned off.
Disconnect the negative terminal of the battery for a few minutes before reconnecting.

2. Reconnect the Battery

Reconnect the positive terminal of the battery first, then the negative terminal.
Tighten the terminals securely to prevent any electrical issues.

3. Resetting the Vehicle Systems

Ignition Reset:
- Insert the key fob into the ignition slot and turn it to the "ON" position without starting the engine.
- Wait for approximately 30 seconds to allow the vehicle systems to initialize.
Infotainment System Reset:
- Press and hold the volume knob on the infotainment system for about 10 seconds until the system reboots.
Window Initialization:
- Lower each window fully and then raise them to the top position, holding the switch for an additional 2 seconds after reaching the top.

- If equipped, open and close the sunroof fully, holding the switch for a couple of seconds at the fully closed position.

Clear any codes that are non-critical.
