Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, tire pressure gauge, flashlight.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection

Sub-steps:
- Remove the hubcaps if applicable.
- Inspect each tire for uneven wear, bulges, or foreign objects.
- Measure and adjust tire pressure according to manufacturer specifications.

3. Undercarriage Inspection

Sub-steps:
- Safely elevate the vehicle using a jack and secure it with jack stands.
- Visually inspect the undercarriage for loose or damaged components such as splash shields, exhaust hangers, and heat shields.
- Tighten any loose bolts or replace damaged components.

4. Brake System Check

Sub-steps:
- Remove the wheel to access the brake assembly.
- Inspect brake pads for wear and the rotors for scoring or warping.
- Ensure calipers are securely mounted and functioning properly.
- Reassemble the wheel after inspection.
