Solution

1. Preparation

Gather tools and parts needed.
Tools Required: OBD-II scanner, socket set, torque wrench, oil filter wrench, shop towels.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Retrieve Error Codes

Use the OBD-II scanner to connect to the vehicle’s diagnostic port.
Record any stored error codes and refer to a diagnostic chart for interpretation.

3. Check Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and then remove it again to check the oil level.
If overfilled, drain excess oil until the correct level is achieved.

4. Inspect Oil Filter

Using the oil filter wrench, carefully remove the oil filter.
Inspect the old filter for any signs of damage and ensure the rubber O-ring is intact.
Install a new oil filter, applying a thin layer of new oil to the O-ring for a better seal, and tighten it according to the manufacturer’s specifications.

5. Tighten Drain Plug

Inspect the drain plug for any leaks and ensure it is properly torqued.
Use a torque wrench to tighten the drain plug to the manufacturer’s specified torque (typically around 25-30 ft-lbs for most Toyota applications).

6. Reset Check Engine Light

After addressing all potential issues, reset the check engine light using the OBD-II scanner.
If the light returns after resetting, further diagnosis may be required.
