This post is to teach you how to diagnostic cars. just
advise
1.
Check the fluids and do a maintenance check of your car.
To do this, check the oil, transmission fluid, and
coolant fluid levels in your car. If the levels look
fine, move on to the maintenance check. This is where you
would spot check your engine for frayed belts, leaking
fluids or anything unusual that stands out to you. If you
find an abnormality during the check, fix that first and
see if your car problem ceases.
2.
Listen for new and strange noises your car is making. A
knocking sound in the engine is serious and needs
immediate attention, whereas a whining sound may be a
belt, which is less serious.
Take note of any strange smells. A chemical-like smell
signifies an electrical problem. A strong exhaust odor
could be a gasket leak or exhaust problem.
3
Look over your vehicle and take note of anything unusual.
If you choose to, take your vehicle into a local car
parts shop. Most of these places offer to do a free code
read of your engine, and may be able to pinpoint any
problems.A code reader is where the
technician can plug a diagnostic tool into your car's
diagnostic port, usually located in the driver's side
lower dash. The tool detects problems in your car and
diagnoses the problem for you.
4
Take your car into a shop, if all else fails. Tell the
mechanic anything you found while trying to diagnose the
problem yourself.

Correction: the scan tool only gives you a DTC, there is a
lot more to diagnostics than just getting a DTC. Some
generic (Genysis) will give you areas to check, but again,
the diagnostics are up to the technician not the tool.
