Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, flashlight
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety precautions before performing any electrical work.

2. Inspect and Repair Leaks

Sub-steps:
1. Visually inspect the engine area for any oil or coolant leaks.
2. If leaks are found, tighten loose fittings or replace damaged seals/gaskets.
3. Clean any residues that might cause odors after repairs.

3. Brake System Inspection

Sub-steps:
1. Raise the vehicle using jack stands and remove the wheels.
2. Inspect brake pads for thickness and signs of overheating.
3. If pads are worn, replace them with OEM or high-quality aftermarket pads.
4. Check calipers for proper operation; replace if they are sticking.

4. Exhaust System Check

Sub-steps:
1. Visually inspect the exhaust pipes and connections for rust or holes.
2. Repair or replace damaged sections of the exhaust system.
3. Ensure all clamps are secure to prevent leaks.

5. Belt and Hose Inspection

Sub-steps:
1. Check all belts for signs of wear, fraying, or burning.
2. Replace any damaged belts with OEM parts.
3. Inspect hoses for cracks or signs of melting; replace as necessary.

6. Transmission Fluid Check

Sub-steps:
1. Check the transmission fluid level using the dipstick.
2. If the fluid is low, top it up with the recommended type (usually ATF).
3. If the fluid appears burnt (dark or has a burnt smell), consider a fluid change.
