Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, brake cleaner, OBD-II scanner
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Brake Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to access the brake components.
3. Inspect brake pads for thickness; replace if worn down to 3mm or less.
4. Inspect rotors for scoring or warping; replace if necessary.
5. Reassemble the brake components and wheels, torque the lug nuts to manufacturer specifications.

3. Inspect and Repair Electrical Components

Sub-steps:
1. Inspect wiring harnesses and connectors in the engine bay for any signs of wear or burning.
2. Repair or replace any damaged wiring using electrical tape or heat-shrink connectors.
3. Reconnect the battery and clear any error codes using the OBD-II scanner.

4. Check Fluid Levels

Sub-steps:
1. Check transmission fluid level and condition; replace if it appears burnt or is low.
2. Check engine oil level and quality; change oil if it has a burnt smell or is dark in color.

5. Exhaust System Inspection

Sub-steps:
1. Inspect the exhaust system for any blockages or leaks.
2. If the catalytic converter is found to be clogged, replace it according to manufacturer specifications.
