Hello welcome to the forum you have made a great choice looking into autel product I see that your 25 years old and like this field maybe already a mechanic or thinking of becoming one I am going to tell you this if you are seriously considering becoming a professional tech do your self a favor and don't buy a code reader as you will always be blind folded you will never know what is wrong with the car you gave a perfect example auto zone discount auto parts code readers you will be as lost as they are trouble codes are hardly the problem of the car but the result of the problem for example a bad catalityc converter will give tps code,air flow meter code o2 sensor codes and more you go and replace all this sensors and you are going to have to because you have a code reader you can not see data you can not do bidirectional etc so there goes a couple of hundreds of dollars down the drain you feel me if I was you i will get me a real scanner if you can not afford a maxisys get your self a maxidas you will not regret it believe me I am not an autel salesman nor tech support just someone that was your age once and was given the same advice very similar to your case back to the scan tool another example 80% of the time to be modest there is a problem with the car and it will not set a code or turn on a check engine light what do you do know if you have a code reader nothing at all and you will also need some source of information like ondemand5 alldata etc, maxidas has come down in price lately if you can not buy a new one get a used one but you will not have the updates anyway my little 2 cents wish you good luck cheers.
