Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to ensure safety.

2. Address Engine Codes

Reconnect the OBD-II scanner and note all retrieved error codes.
Research each code to determine the relevant components that may require inspection or replacement.

3. Inspect and Replace Fluids

Check engine oil:
- Remove dipstick, wipe clean, reinsert, and check level.
- If low, top up with the manufacturer-recommended oil.
Check brake fluid:
- Inspect the reservoir and add fluid as needed to the recommended level.

4. Electrical System Check

Reconnect the battery.
Start the engine and use a multimeter to check the battery voltage (should be around 12.6V when off and 13.7-14.7V when running).
Replace the battery or alternator if voltages are outside the specified ranges.

5. Brake System Inspection

Remove the wheel to access brake components.
Inspect brake pads and rotors for wear; replace if thickness is below manufacturer specifications.
Check brake lines for leaks and secure connections.
