Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools: OBD-II scanner, socket set, multimeter, flashlight.
Safety warning: Disconnect the battery before working on electrical components.

2. Inspect Engine Components

Remove the engine cover (if applicable) using the socket set.
Visually inspect wiring harnesses for fraying or damage.
Check for any foreign materials or debris on exhaust components.
Look for signs of oil leaks or coolant leaks around the engine.

3. Replace Cabin Air Filter

Locate the cabin air filter compartment inside the vehicle (usually under the dashboard).
Remove the cover and extract the old filter.
Install a new cabin air filter, ensuring it is oriented correctly.
Replace the cover securely.

4. Repair Exhaust System

If a leak is detected, identify the section of the exhaust that is compromised.
Use a socket set to remove damaged sections of the exhaust.
Install new exhaust components or use exhaust repair tape for minor leaks.
Tighten all connections to the manufacturer's torque specifications.

5. Check Coolant System

Inspect the coolant reservoir for proper levels and signs of leaks.
If the coolant level is low, refill with the appropriate coolant type as specified in the owner's manual.
Inspect hoses for cracks or signs of wear, replacing any damaged hoses.
