Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, socket set, and cleaning tools.
Ensure the vehicle is parked on a flat surface with the engine off and the key removed.

2. Battery Inspection

Remove the negative terminal from the battery using a socket wrench.
Clean the battery terminals using a wire brush to remove any corrosion.
Reconnect the negative terminal securely.

3. Alternator Testing

Start the engine and let it idle.
Use a multimeter to measure the voltage at the battery terminals. It should read between 13.7 and 14.7 volts.
If the voltage is outside this range, consider replacing the alternator.

4. Ground Connection Check

Locate the ground connections, typically found near the battery and connected to the chassis.
Inspect and clean any connections that appear corroded or loose.
Tighten any loose bolts or screws that secure the ground wires.

5. Fuse Inspection

Locate the fuse box and remove the cover.
Check all fuses related to the dashboard and electrical systems for continuity.
Replace any blown fuses with the same amperage rating.
