Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, and basic hand tools (sockets and wrenches).
Ensure the vehicle is in a safe area, preferably with the engine off and the vehicle in park.
Wear safety gloves and goggles for protection.

2. Check Battery Voltage

Use a multimeter to measure the voltage at the battery terminals.
- Normal voltage should read between 12.4V and 12.7V for a fully charged battery.
- Action: If the voltage is below 12.4V, proceed to charge or replace the battery.

3. Disconnect Battery

Locate the negative battery terminal (usually marked with a "-" sign).
Using a socket wrench, loosen the nut and disconnect the negative terminal.
Ensure the terminal is secure and not touching any metal surfaces to prevent accidental reconnection.

4. Reset the Vehicle Systems

Leave the battery disconnected for at least 10 minutes to allow the systems to fully reset.
After the waiting period, reconnect the negative battery terminal and tighten the nut securely.

5. Verify System Functionality

Start the vehicle and check if the instrument cluster and infotainment system are functioning.
If issues persist, connect the OBD-II scanner to check for any stored error codes and address as necessary.
