Solution

1. Preparation

Gather tools such as an OBD-II scanner, flashlight, and safety gloves.
Ensure the vehicle is parked on a level surface with the engine off.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard.
Turn the ignition key to the "ON" position without starting the engine.
Retrieve error codes and document them for analysis.
Clear error codes and monitor if the warning light returns after restarting the engine.

3. Inspect Fluid Levels

Open the hood and check the engine oil using the dipstick, adding oil if low.
Check the coolant reservoir for appropriate levels and top off if necessary.
Inspect brake fluid, transmission fluid, and power steering fluid levels.

4. Address Specific Warning Indicators

If the warning light indicates a low fuel condition, refuel the vehicle.
For airbag or seatbelt warnings, inspect seatbelt connections and ensure they are properly latched.

5. Reset Warning Light (if applicable)

If the issue is resolved and no fault codes remain, use the OBD-II scanner to reset the warning light.
Test drive the vehicle to ensure the warning light does not reappear.
