Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, jack and jack stands, torque wrench, flashlight.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Worn Belts

Sub-steps:
1. Remove the engine cover if applicable (tools: socket set).
2. Visually inspect serpentine and timing belts for cracks, fraying, or signs of wear.
3. If damaged, loosen the tensioner using the appropriate socket and remove the old belt.
4. Install the new belt following the manufacturer's routing diagram.
5. Re-tension the belt as per specifications (usually around 90-100 Nm).

3. Examine and Replace Tires

Sub-steps:
1. Inspect all tires for uneven wear patterns, bulges, or damage.
2. If tires are significantly worn, remove them using a jack and a tire iron.
3. Install new tires if necessary, ensuring they are properly balanced and inflated to the recommended pressure.

4. Check Brake System

Sub-steps:
1. Remove the wheel to access the brake components (tools: jack, jack stands, tire iron).
2. Inspect brake pads for wear and replace if they are worn down to the minimum thickness.
3. Check the calipers and rotors for signs of overheating (blue discoloration).
4. Lubricate sliding pins and ensure calipers move freely.
5. Reassemble the wheel and lower the vehicle.

5. Inspect Electrical Components

Sub-steps:
1. Check the wiring harnesses for any melted insulation or exposed wires.
2. If damaged wires are found, repair or replace them using electrical tape or connectors.
3. Reconnect the battery and ensure all electrical connections are secure.
