Solution

1. Preparation

Gather tools and materials including an OBD-II scanner, socket set, and replacement oil if necessary.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Follow the scanner instructions to read and record any error codes.
Clear the codes from the system and disconnect the scanner.

3. Check and Adjust Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick fully and then remove it again to check the oil level.
If the oil level is low, add the appropriate oil type and viscosity as specified in the owner’s manual.

4. Inspect Oil Filter

Locate the oil filter and check for proper installation (tightness and orientation).
If leaking, replace the oil filter, ensuring to lubricate the rubber O-ring with fresh oil before installation.

5. Verify Connections

Inspect all electrical connections and hoses around the engine, particularly those that may have been disconnected during the oil change.
Reconnect any loose connections and ensure all hoses are secure.
