Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, torque wrench, and safety glasses.
Ensure the vehicle is parked on a flat surface and the engine is cool before beginning.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any error codes present and refer to the service manual for specific troubleshooting steps related to those codes.

3. Fluid Level Check

Open the hood and check engine oil level using the dipstick; top off if necessary with the recommended oil type.
Inspect the coolant reservoir and refill with the appropriate coolant mixture if low.

4. Battery Inspection

Disconnect the negative terminal of the battery.
Clean any corrosion on terminals using a wire brush.
Reconnect the battery and ensure the connections are tight.

5. Air Filter Inspection

Remove the air filter housing cover using a socket set.
Inspect the air filter for dirt and debris; replace it if it appears clogged.

6. Fuel System Check

Using the fuel pressure gauge, connect it to the fuel rail.
Turn the ignition to the ON position (without starting the engine) to check for proper fuel pressure. It should match the manufacturer’s specification.
If fuel pressure is low, inspect the fuel pump and filter for issues.

7. Test Drive and Recheck

Start the vehicle and take it for a short test drive to monitor performance.
After the drive, re-scan with the OBD-II scanner to see if the warning light has cleared.
