Solution

1. Preparation

Gather tools: socket set, OBD-II scanner, multimeter, and rags for cleanup.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Addressing Leaks

If fluid leaks are found:
- Oil Leak: Replace damaged gaskets or seals. Clean the area and check for re-leaks after repairs.
- Coolant Leak: Replace hoses or the radiator if damaged. Ensure proper refilling of coolant.
- Transmission Fluid Leak: Inspect the transmission pan and seals; replace as necessary.
Reconnect the battery after repairs.

3. Brake Inspection

Remove the wheel to access the brake components.
Inspect brake pads for wear; replace if they are excessively worn or burnt.
Check for any stuck calipers or damaged brake lines; replace defective parts.

4. Engine and Exhaust Check

Inspect the exhaust system for any signs of damage or blockages.
Look for burnt wires or components near the engine; replace any damaged wiring or connectors.
If necessary, clean or replace the catalytic converter if it is causing excessive heat.

5. Final Assembly

Reassemble all components carefully after inspection and repairs.
Ensure all connections are secure, and fluids are topped off.
Reconnect the battery.
