Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical issues while inspecting.

2. Retrieve and Analyze Codes

Use the OBD-II scanner to retrieve any error codes.
Document the codes and research their meanings to identify the problem areas.

3. Inspect and Address Fluid Levels

Check oil level and quality; replace if low or contaminated.
Inspect coolant level in the reservoir; top off or replace as needed.
Verify brake fluid level and condition; replace if necessary.

4. Battery and Charging System Check

Use a multimeter to test the battery voltage (should be around 12.6 volts).
Inspect battery terminals for corrosion and clean if necessary.
Check the alternator output to ensure it is charging properly (should be between 13.7 to 14.7 volts).

5. Address Specific Errors

Based on the error codes retrieved, replace or repair the indicated components (e.g., O2 sensors, ignition coils, etc.).
Clear error codes using the OBD-II scanner after repairs.

6. Final Checks

Reconnect the battery.
Start the engine and observe if the warning light remains illuminated.
