Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid measuring tools, torque wrench.
Review the retrieved error codes from the OBD-II scan to identify specific issues that need to be addressed.
Gather necessary parts and fluids based on the required service (oil, filters, etc.).

2. Perform Maintenance Services

2.1. Oil Change

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Drain the old engine oil by removing the oil drain plug with a socket wrench. Allow oil to completely drain into a pan.
- Replace the oil filter using an oil filter wrench; apply a small amount of fresh oil to the new filter's gasket before installation.
- Reinstall the drain plug and torque to manufacturer specifications (typically around 25-30 Nm).
- Fill the engine with new oil through the oil filler cap, using the recommended oil type (usually 0W-20 or 5W-30).

2.2. Fluid Check and Replacement

Sub-steps:
- Check and top off the coolant in the reservoir if low, using the recommended coolant type.
- Inspect and replace brake fluid if it appears dark or contaminated.
- Check power steering fluid and transmission fluid levels, topping off as necessary.

3. Reset Service Light

Sub-steps:
- Using the OBD-II scanner, select the option to clear the service light codes.
- Alternatively, follow the vehicle's specific procedure to reset the service light using the dashboard controls.
