Solution

1. Preparation

Gather tools including an OBD-II scanner, socket set, torque wrench, and fluid replenishment tools.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Diagnostic Trouble Codes (DTCs)

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Access and document any trouble codes. Research codes to determine necessary repairs or maintenance.

3. Perform Required Maintenance

Engine Oil Change

Remove the oil drain plug using a socket wrench and drain the old oil into a catch pan.
Replace the oil filter with a new one using an oil filter wrench.
Reinstall the drain plug and tighten to manufacturer specifications (typically around 25-30 Nm).
Fill the engine with new oil as per manufacturer recommendations (usually 5W-30 or 0W-20).

Fluid Checks

Inspect and top off other fluids (coolant, brake fluid, transmission fluid) as necessary.

Tire Maintenance

Check the tire pressure; inflate to the recommended PSI.
Inspect tread depth and condition; replace tires if they are worn.

4. Reset Service Light

With the ignition on, press the gas pedal three times within 10 seconds.
Turn off the ignition and restart the vehicle to verify that the service light has reset.
