Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts while working.

2. Fluid Check and Replacement

Engine Oil:
- Check oil level; top off or change if it's low or dirty.
- Use manufacturer-recommended oil type.
Transmission Fluid:
- Check for proper level and condition; replace if burnt.
- Use specified transmission fluid type.

3. Brake System Inspection and Repair

Remove Wheels:
- Use a jack and jack stands to lift the vehicle; remove the wheels.
Inspect Brake Pads and Rotors:
- Check for wear; replace pads if they are below the manufacturer’s specifications.
- Replace rotors if they are scored or excessively worn.
Bleed Brake Lines:
- If brake fluid was low, bleed the brake lines to remove air bubbles.

4. Electrical System Examination

Inspect Wiring:
- Look for any signs of wear, fraying, or melting of insulation.
- Replace any damaged wiring using the appropriate gauge wire.
Test Electrical Components:
- Use a multimeter to check the functionality of components like the alternator and starter.
