If you are investigating a drivetrain noise that appears while coasting, save every stored and pending code before clearing anything. An engine-only scan may not identify wheel bearings, gears, or tires. Record the engine temperature and load alongside the reading; the same value can mean different things in different conditions.
A basic reader may not access every module. Check for tire damage and visible fluid leaks without going under an unsupported car. Use the exact vehicle’s service information to interpret the result.
Quick educational note
For information, not a diagnosis or repair instruction. Vehicle-specific checks are still required. Consult the manufacturer's guidance and a qualified technician.
