Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jack and jack stands, safety goggles, gloves.
Safety precautions: Disconnect the battery to prevent electrical shocks or shorts.

2. Inspect and Repair Electrical Components

Inspect wiring: Remove covers and inspect all wiring harnesses for signs of damage or melting.
- If damaged, replace the affected wiring using proper gauge wire and connectors.
Test fuses: Use the multimeter to check for continuity in fuses; replace any blown fuses with the correct amperage rating.

3. Address Fluid Issues

Change burnt fluids: If fluid levels are low or fluids have a burnt smell, drain and replace with manufacturer-recommended fluids.
- Torque to specifications when reassembling any components.
Inspect and clean: Use a degreaser to clean areas where fluid leaks were found; ensure all seals and gaskets are properly functioning.

4. Brake System Inspection

Inspect brake pads and rotors: Check for excessive wear or overheating.
- Replace brake pads and resurfacing or replacing rotors if necessary.
Check brake fluid: If the fluid is contaminated or burnt, flush and replace with new fluid.

5. Reassemble and Test

Reconnect battery: After all repairs are made, reconnect the battery and ensure all connections are secure.
Test drive: Take the vehicle for a short drive to monitor for any return of the burning smell or warning lights.
