Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, rags for cleaning.
Ensure the vehicle is parked on a level surface, and the engine is cool before starting.
Disconnect the battery to avoid electrical shorts.

2. Identify Source of Burning Smell

Step 1: Start the engine and allow it to idle. Carefully observe any smoke or vapor emissions.
Step 2: Use the OBD-II scanner to read and clear any error codes.
Step 3: While the engine is running, systematically check for burning smells near components such as the alternator, exhaust, and electrical connectors.

3. Repair or Replace Affected Components

Step 1: If burnt wiring is found, trace the damaged wire and replace it with the appropriate gauge wire.
Step 2: If overheating fluid levels are low, locate the leak, repair it (e.g., replacing hoses or gaskets), and refill with the correct fluid types (engine oil and coolant).
Step 3: If brake components are overheating, inspect and replace worn brake pads or rotors as necessary.
Step 4: For damaged belts or hoses, remove the old component using a socket set and replace it with a new part, ensuring proper tension and alignment.
