Solution

1. Preparation

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

2. Addressing Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes for reference.
Clear the codes and take the vehicle for a test drive to see if the warning light reappears.

3. Fluid Checks

Inspect engine oil: Remove the dipstick, wipe it clean, reinsert, and check the level. Top off if low with the manufacturer's recommended oil.
Check coolant level: Open the coolant reservoir and ensure the level is within the recommended range. If low, add the appropriate coolant mix.
Inspect brake fluid: Check the brake fluid reservoir and add fluid if necessary.

4. Electrical System Inspection

Check battery voltage with a multimeter (should be around 12.6 volts).
Inspect battery terminals for corrosion and ensure tight connections.
Test the alternator output (should be around 13.7 to 14.7 volts while the engine is running).

5. Fuse Inspection

Locate the fuse box and identify the relevant fuses associated with engine and warning systems.
Replace any blown fuses with the same amperage rating.

6. Final Checks

Reconnect the battery terminal.
Start the engine and monitor for the warning light and any abnormal behavior.
Conduct a test drive to ensure all systems are functioning properly.
