⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Ensure the engine is cool before inspecting components.

Symptoms

•Burning smell, possibly resembling burnt oil or rubber
•Check engine light illuminated (potentially)
•Smoke from engine bay or undercarriage (if applicable)
•Overheating of the engine (if applicable)
•Unusual noises from the engine or electrical components
•Fluid leaks detected beneath the vehicle

Diagnostic Steps

1
Check under the hood for any visible signs of leaks, burnt components, or loose wiring.
2
Use an OBD-II scanner to check for any stored error codes that might indicate specific issues.
3
Check oil, coolant, and transmission fluid levels to ensure they are at appropriate levels and not leaking.
4
Inspect battery terminals, wiring harnesses, and connectors for signs of damage or corrosion.
5
Monitor the engine temperature gauge to see if the engine is running hotter than normal.
6
Inspect for any oil, coolant, or brake fluid leaks that could be causing the burning smell.
