Solution

1. Preparation

Ensure you have the vehicle parked on a flat surface, and engage the parking brake.
Disconnect the battery to avoid any electrical issues while working on the vehicle.

2. Inspect and Address Engine Leaks

Tools Required: Socket set, rags for cleanup
Check for oil leaks by looking under the vehicle and around the engine components.
If oil is found, clean the area and replace any damaged gaskets or seals.
Refill any low fluids and reconnect the battery.

3. Brake System Inspection

Tools Required: Jack and jack stands, torque wrench, brake cleaner
Jack up the vehicle and remove the wheels to access the brake components.
Inspect brake pads and rotors for wear. Replace pads if they are thin or burnt.
Clean any debris or burnt material from the brakes using brake cleaner.
Reinstall wheels and torque them to manufacturer specifications.

4. Electrical System Check

Tools Required: Multimeter, electrical tape
Inspect all wiring and connectors for any signs of melting or damage.
Use a multimeter to check for continuity in circuits with visible damage.
Repair or replace damaged wiring as necessary, and secure all connections.

5. Exhaust System Inspection

Tools Required: Visual inspection, possibly a smoke test kit if available
Inspect the exhaust system for any blockages or damage.
If any signs of burning are present, replace damaged sections of the exhaust.
