⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow engine to cool before opening the hood or inspecting components.

Symptoms

•Burning smell noticeable inside or outside the vehicle
•Warning lights illuminated on the dashboard
•Smoke observed from under the hood or near the wheels
•Engine overheating or temperature gauge rising
•Loss of power or performance during driving

Diagnostic Steps

1
Visual Inspection**: Check for any visible signs of smoke or burning in the engine bay, wheel wells, or underbody.
2
Check Fluid Levels**: Inspect engine oil, coolant, and brake fluid levels for any leaks or low levels.
3
Scan for Error Codes**: Use an OBD-II scanner to check for diagnostic trouble codes (DTCs) related to the engine or electrical systems.
4
Examine Electrical Connections**: Inspect wiring and connectors for signs of damage, melting, or corrosion.
5
Inspect Brakes**: Check brake components for excessive wear or overheating, especially if the smell is stronger when driving.
6
Test Components**: Use a multimeter to test the function of electrical components and check for short circuits or overloads.

Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, cleaning supplies.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspecting components.

2. Resolve Fluid Leaks

Identify the source of any fluid leaks, particularly oil or coolant.
If a leak is found:
1. Clean the affected area with appropriate cleaning supplies.
2. Replace any damaged seals, gaskets, or hoses.
3. Refill fluids to the appropriate levels.

3. Repair Electrical Issues

If damaged wiring or connectors are present:
1. Cut and strip the damaged wire ends.
2. Use heat shrink tubing or electrical tape to insulate the repaired area.
3. Replace any corroded connectors with new ones.

4. Address Brake Problems

If brakes are found to be overheating:
1. Remove the wheel and inspect brake pads and rotors for wear.
2. Replace worn brake pads and machine or replace rotors as necessary.
3. Ensure the caliper slides freely and is not seized.

5. Clear Codes and Test Drive

After repairs, reconnect the battery and clear any error codes.
Test drive the vehicle under varied conditions to ensure the issue is resolved.
