Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire brush, and protective gloves.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Battery Inspection

Remove the negative (-) battery terminal using a socket set.
Clean any corrosion on the battery terminals with a wire brush.
Ensure the connections are tight and secure before reconnecting the battery.

3. Alternator Testing

Start the engine and connect the multimeter to the battery terminals.
Verify the voltage is between 13.5 to 14.5 volts; if not, the alternator may need to be replaced.

4. Fuse Inspection

Locate the fuse box (usually under the dashboard or near the engine compartment).
Remove the fuse for the dashboard lights and inspect it for damage; replace if blown.
Check all related fuses for continuity and replace as necessary.

5. Wiring Inspection

Visually inspect wiring harnesses leading to the dashboard for signs of wear or damage.
Repair or replace any damaged wires as needed.
