Solution

1. Preparation

Gather all required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Address the Error Codes

Connect the OBD-II scanner and note any error codes.
Clear the codes from the system and see if the warning light returns after a test drive.
If the warning light returns, proceed with further diagnosis based on the specific error codes.

3. Fluid Inspection and Replacement

Engine Oil:
- Check the oil level using the dipstick; add oil if necessary.
- If low, consider an oil change if the oil is dirty or due for service.
Coolant:
- Inspect the coolant level in the reservoir; top off if it’s low.
- If coolant is low, check for leaks in hoses or the radiator.
Brake Fluid:
- Check the brake fluid level; refill if necessary.
- Inspect brake lines for leaks or corrosion.

4. Electrical System Check

Inspect the battery for corrosion on terminals and ensure tight connections.
Test battery voltage with a multimeter (should be around 12.6 volts when fully charged).
If the battery is weak, replace it with a compatible unit.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the engine and observe if the warning light is still illuminated.
Conduct a test drive to ensure all systems are functioning properly.
