Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, jack and jack stands, basic hand tools (sockets, wrenches).
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Locate the serpentine belt routing diagram, typically found on a sticker in the engine bay.
2. Use a socket to relieve tension on the belt tensioner and remove the serpentine belt.
3. Inspect the belt for cracks, fraying, or signs of melting. If damaged, replace with a new belt.

5. Reconnect the battery.

3. Examine and Repair Brake System

Sub-steps:
1. Raise the vehicle using the jack and secure it with jack stands.
2. Remove the wheels to access the brake components.
3. Inspect brake pads for glazing (shiny surface) and check calipers for proper operation.
4. If pads are worn or glazed, replace them along with any damaged calipers as necessary.
5. Reinstall the wheels and lower the vehicle to the ground.

4. Check Electrical Components

Sub-steps:
1. Inspect wiring and connectors in the engine bay for signs of wear or damage.
