Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, flashlight, and gloves.
Ensure the vehicle is parked on a flat surface and the engine is cool before beginning any work.

2. Inspect Engine Components

Step 1: Check for oil leaks.
- Clean any spilled oil with a degreaser to identify the source of leaks.
- Replace any damaged gaskets or seals if leaks are found.
Step 2: Examine the engine oil.
- If oil is burnt or contaminated, perform an oil change.
- Use the manufacturer-recommended oil type and viscosity.
Step 3: Inspect belts and hoses.
- Look for fraying or cracks; replace any damaged belts or hoses.

3. Electrical System Check

Step 1: Inspect wiring and connectors.
- Look for corrosion or burn marks, especially near high-heat areas.
- Replace damaged wiring or connectors as necessary using appropriate gauge wire.
Step 2: Test electrical components.
- Use a multimeter to check the voltage and continuity of components suspected to be faulty.
- Replace any components that fail the tests.

4. Brake System Inspection

Step 1: Check brake pads and rotors.
- Inspect pads for wear and rotors for overheating signs (blue discoloration).
- Replace worn pads and resurface or replace rotors as needed.

5. Exhaust System Examination

Step 1: Inspect for blockages or damage.
- Check for dents, rust, or other damages along the exhaust pipes and catalytic converter.
- Replace any damaged sections of the exhaust system.
