Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, brake cleaner, rags, new oil and filter if needed, new transmission fluid if necessary.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before starting work on electrical components.

2. Check and Change Engine Oil

Remove the oil dipstick and check the oil level.
If the oil is low or appears burnt, drain the old oil using a socket set to remove the oil pan bolt.
Replace the oil filter using an oil filter wrench.
Refill the engine with fresh oil of the correct specification (check the owner's manual for oil type and capacity).

3. Inspect and Replace Brake Pads (if applicable)

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect brake pads and rotors for wear; if pads are worn down, remove the caliper bolts with a socket set.
Replace pads with new ones and reassemble the brake system, ensuring proper torque specifications are followed.

4. Check Transmission Fluid

Locate the transmission dipstick and check the fluid level.
If the fluid is low or burnt, drain the transmission fluid by removing the drain plug using the socket set.
Replace with new transmission fluid of the correct type, ensuring to fill to the appropriate level.
