why does my Toyota Highlander XU70 (2020-Present) have a burning smell

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, multimeter, flashlight, brake cleaner, rags.
• Safety Warnings: Allow the engine to cool down before starting any inspection. Disconnect the battery when working on electrical systems.

2. Address Fluid Leaks

• Inspect the engine bay and undercarriage for leaks.
• If a leak is found, identify the source (e.g., oil pan, coolant hoses) and replace damaged seals or hoses as necessary.

3. Repair Electrical Issues

• For damaged wiring, cut out the damaged section and splice in new wiring, ensuring proper insulation.
• Replace any burnt fuses or connectors found during inspection.

4. Replace Worn Components

• If brake components are worn, remove the wheel and brake assembly.
• Replace brake pads, rotors, or calipers as needed, ensuring proper torque specifications during reassembly (typically 85-100 ft-lbs for caliper bolts).

5. Clean and Reassemble

• Use brake cleaner to clean any burnt debris from the affected area.
• Reassemble any components removed during inspection, ensuring all connections are tight and secure.
