Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wire brush.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Clean Battery Terminals

Use a wire brush to remove any corrosion from the battery terminals.
Reconnect the terminals securely and ensure there are no loose connections.

3. Test Battery and Alternator

Reconnect the negative battery terminal.
Start the vehicle and use a multimeter to measure battery voltage; it should read between 12.6V and 12.8V when off and 13.7V to 14.7V when running.
If the alternator output is low, consider replacing the alternator.

4. Inspect and Replace Fuses

Locate the fuse box and check the relevant fuses for the dashboard lights and electrical components.
If any fuses are blown, replace them with the same amperage rating.

5. Inspect Wiring and Connectors

Visually inspect the wiring harnesses and connectors behind the dashboard.
Repair or replace any damaged wires or connectors.
