Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, tire pressure gauge, socket set.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical systems.

2. Tire Inspection

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure. Inflate to manufacturer specifications if low.
- Inspect tires for uneven wear or damage. Replace if necessary.

3. Brake System Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the brake components.
- Inspect brake pads and rotors for wear. Replace pads if thickness is below 3mm and rotors if they are warped or worn beyond specifications.
- Check for caliper movement; if the caliper is seized, it may need to be rebuilt or replaced.

4. Drivetrain and Transmission Check

Sub-steps:
- Inspect CV joints for any tears or damage.
- Check differential fluid, ensuring it is at the correct level and in good condition. Replace if contaminated.
- Check the transmission fluid level using the dipstick; if low, top up with the appropriate fluid type.

5. Final Assembly

Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 76 ft-lbs for RAV4).
Lower the vehicle and reconnect the battery.
