Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the negative battery terminal to ensure safety.

2. Scan for Diagnostic Codes

Reconnect the battery and connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition (do not start the engine) and read the error codes.
Document any error codes for further analysis.

3. Inspect the Battery and Alternator

Use a multimeter to check the battery voltage (should be around 12.6 volts with the engine off).
Start the engine and check the alternator output (should be between 13.7 to 14.7 volts).
If the output is outside this range, consider replacing the alternator.

4. Check Fuses

Locate the fuse box (refer to the owner's manual for location).
Inspect all fuses related to the dashboard and electrical systems.
Replace any blown fuses with the same amperage.

5. Examine Wiring and Connectors

Visually inspect all wiring harnesses connected to the dashboard for signs of wear or damage.
Check connectors for corrosion or loose connections and ensure they are secure.

6. Test Ignition System

Inspect ignition components such as the starter and relays.
Use a multimeter to test for continuity and proper operation.
