Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface and the engine is cool.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Engine Oil (if necessary)

Sub-steps:
1. Remove the oil dipstick and check oil level; add oil if low.
2. If oil appears burnt or dirty, drain the oil using a wrench to remove the oil drain plug and allow it to fully drain.
3. Replace the oil filter using an oil filter wrench.
4. Reinstall the drain plug, ensuring it is tightened to manufacturer specifications (usually around 25-30 ft-lbs).
5. Refill the engine with fresh oil per manufacturer specifications (typically 0W-20 for this model).

3. Check and Repair Cooling System

Sub-steps:
1. Inspect the radiator and hoses for leaks; replace any damaged hoses.
2. If coolant is low, refill with the proper coolant type (usually Toyota Long Life coolant).
3. Inspect the water pump for leaks and replace if necessary.
4. Check the thermostat operation and replace if it is stuck closed.

4. Inspect and Replace Brake Components (if necessary)

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect brake pads for wear; replace if thinner than 3 mm.
3. Check the brake rotor for overheating signs; replace if warped or excessively worn.
4. Ensure the caliper is functioning correctly and not sticking.

5. Inspect Electrical Components

Sub-steps:
1. Visually inspect wiring harnesses for any signs of fraying or melting.
2. Repair or replace any damaged wiring.
3. Check battery terminals for corrosion and ensure tight connections.

6. Inspect Belts and Hoses

Sub-steps:
1. Check all engine belts for signs of wear, cracks, or noise.
2. Replace any damaged belts with OEM parts.
3. Inspect hoses for leaks or bulges and replace as needed.
