Solution

1. Preparation

Tools Required: Wheel chocks, jack stands, socket set, flashlight, OBD-II scanner.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Open the hood and visually inspect the serpentine belt for cracks, fraying, or signs of wear.
2. If the serpentine belt is damaged, use a socket set to relieve tension on the tensioner pulley and remove the belt.
3. Replace the serpentine belt with a new one, ensuring it is routed correctly according to the belt routing diagram.

3. Brake System Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to access the brake components.
3. Inspect brake calipers and pads for signs of wear or sticking.
4. If the calipers are seized or pads are worn, replace them as necessary.

4. Check for Foreign Objects

Sub-steps:
1. Inspect the wheel wells and undercarriage for debris that may be causing friction, such as plastic or rubber parts.
2. Remove any foreign objects found.

5. Test Drive and Further Inspection

Sub-steps:
1. Start the engine and let it idle while checking for any unusual noises.
2. Take the vehicle for a short test drive to determine if the smell persists.
3. If the burning smell continues, further inspection of the transmission or other components may be necessary.
