Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner's prompts to read and record any error codes.

3. Inspect Battery and Alternator

Reconnect the battery terminal.
Use a multimeter to check the battery voltage; it should read between 12.4V and 12.7V when the engine is off.
Start the engine and check the voltage again; it should be between 13.7V and 14.7V.
Ensure the battery terminals are clean and tight.

4. Check Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove and visually inspect each fuse related to the dashboard and electrical systems.
Replace any blown fuses with the same amperage rating.

5. Inspect Wiring and Ground Connections

Visually inspect wiring harnesses for frayed or damaged wires.
Clean any corroded connectors using electrical contact cleaner.
Ensure all ground connections are secure and free of corrosion.
