Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, replacement fuses if needed.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative terminal of the battery for safety.

2. Inspect Battery Connections

Sub-steps:
1. Remove the battery cover if applicable.
2. Check the battery terminals for tightness and corrosion. Clean with a wire brush if necessary.
3. Reconnect the battery terminals securely.

3. Check and Replace Fuses

Sub-steps:
1. Locate the fuse box and remove the cover.
2. Identify any blown fuses related to dashboard lights.
3. Replace blown fuses with new ones of the same amperage.

4. Test Voltage Output

Sub-steps:
1. Reconnect the battery negative terminal.
2. Set the multimeter to DC voltage and measure across the battery terminals.
3. A healthy battery should read between 12.4 to 12.7 volts when the vehicle is off and about 13.7 to 14.7 volts with the engine running.

5. Inspect Alternator

Sub-steps:
1. Start the engine and measure the voltage output at the battery again.
2. If the voltage is below the specified range, inspect the alternator belt for wear and tension.
3. If the alternator is faulty, replace it following manufacturer guidelines.
